FIRE SUPPRESSION SYSTEM ADDS PROTECTION FLUID
ELECTRICALLY-ACTUATED PRECISION SPRAY NOZZLES
Fike has announced it will now offer 3M Novec 1230 fire protection fluid in its patented Impulse Valve Technology fire suppression system. The company’s fire suppression systems are manufactured with impulse valve technology to improve the release of the agent into the zone with greater precision and reliability. The patented valve uses the Fike AXIUS rupture disc, enabling systems with smaller diameter pipe, longer flow distances and greater design flexibility than most other systems, the company says. The fire protection fluid is waterless, discharged as a gas, leaves no residue, and is electrically non-conductive, making it suitable for quickly extinguishing fires in spaces occupied by electronics or irreplaceable assets and where business continuity is critical. Its environmental profile supports sustainability and LEED initiatives with zero ozone depleting potential and a global warming potential that’s less than one. Fike www.fikecanada.com
HAND PUMP SPEEDS PRESSURE, VACUUM CALIBRATION
The DCAP-PV pump from Ralston Instruments is said to generate pressure and vacuum easily and then control pressure to very precise test points. If the transmitter is an absolute pressure transmitter, the hand pump can generate a vacuum to reach below ambient pressure test points. The Ralston Quick-test system of hoses and connectors also lets the user connect without thread tape to each adapter and in many cases also to the device being calibrated without a wrench. For setting pressure switches, a pump with good control of pressure or vacuum is required. The fine adjust piston on the hand is said to very precise and lets the user open or close a pressure switch easily. In addition, the hand pump works well for calibrating flow computers which require precise control of pressure to each side of the differential pressure cell, the company says.

BETE electrically-actuated hydropulse spray nozzles from John Brooks Company are available for hygienic (EHP) and industrial (EHPI) applications. Units are said to assure precision volumes are sprayed directly onto your processing target, with overspray waste virtually eliminated. The automated nozzles don’t require a compressed air source and are capable of cycling on/off up to 150 cycles per second. These features afford the option of using high-frequency cycling known as pulse width modulation (PWM) to vary the liquid spray flow rate at constant supply pressure with little change in spray performance by adjusting the duty cycle. When the spray cycles at a high enough frequency, coverage uniformity is maintained because the duration between pulses of spray is short enough to ensure there are no gaps in the spray coverage, the company says.

WEIGHERS/FEEDERS OPERATE IN WILD-FLOW OR CLOSED-LOOP CONFIGURATIONS
Acrison offers its various high capacity, heavy-duty model 260 weigh belt weighers/feeders to accurately weigh and/or totalize the flow of dry materials in a “Wild-Flow” configuration, or to meter dry solid materials in a controlled, “Closed-Loop” configuration as a weigh feeder. The model 260 (WF), operates as a weigher and/or totalizer, continuously weighs material passing across the belt while producing an output signal directly proportional to the weight of product flow. Belt speed is constant, and the rate of flow is not controlled, only weighed, by the weigher’s multiprocessor controller. When operating as a weigh feeder, the model 260 (F) continuously controls the feed rate (or rate of product discharge off the belt) in relation to a feed rate setpoint via modulation of the belt speed by a multiprocessor-based control system. .

Hazardous area classification considerations: flammability and combustibility risks
By Wayne Perry
In the past, seeing the term “Hazardous Location” usually meant that the equipment being requested was destined for a chemical plant, refinery, or drilling platform. Today, we are seeing hazardous locations in sugar mills, grain storage facilities, and anywhere there may be flammable liquids, gases, or dust present. Hazardous areas are defined as areas where the presence of flammable gases or liquids, combustible dusts, or easily ignited fibers exist in sufficient concentrations to cause a fire or explosion, provided a source of ignition. These areas range from portions of a room to whole plant sites.
Partly due to this expanded use of the classification system, specifiers are increasingly citing requirements for equipment suitable for use in classified areas. When properly used, the hazardous area classification system makes for a safer work environment. Too often, however, hazard classes are specified without concern for the significantly higher design and procurement costs they bring. In many cases, an open mind and a little ingenuity can avoid excessive costs for compressors and other equipment, without compromising safety.
Classification Systems
There are some differences between the classification system in North America and the system used in other parts of the world. In North America, the most common method for defining hazardous areas is by Class, Division, and Group.
Classes are used to identify the type of material that may be found in the atmosphere:
• Class I – Flammable gases and vapours in quantities sufficient to produce ignitable or explosive mixtures
• Class II – Combustible or conductive dusts present in the atmosphere
• Class III – Ignitable fibres or flyings are in the atmosphere, but not likely to be in sufficient quantities to produce ignitable mixtures.
Divisions are used to identify the probability that an ignitable substance will be in the atmosphere in concentrations that would support ignition:
• Division 1 – The substance is present during normal operating conditions. This is further defined as being more than 10 hours per year.
• Division 2 – The substance is not present during normal operating conditions and is present only when an abnormal condition exists. This is further defined as being between 1 hour and 10 hours per year.
• Unclassified – In a facility with Class I or Class II areas, any area where concentrations of gases, vapours, or dust sufficient for ignition are present less than 1 hour per year are listed as Unclassified.
Groups are listed as A through G. Groups A through D identify gases and vapors and apply to Class I locations. Groups E through G identify combustible dusts and apply to Class II locations. The degree of flammability is alphabetical, with A being the most flammable and D being the least flammable gases and vapours, and E being the most flammable and G being the least flammable dusts.
These classifications can be found in National Fire Protection Association (NFPA) Section 500 and 505. Section 505 is a newer s In Europe and other parts of the world, a Zone rating is used. This is similar to the North American system with some slight differences.
• Zone 0 – An atmosphere where a mixture of air and flammable gas, vapour, or mist is present frequently, continuously, or for long periods of time. This is further defined as 1000 hours per year or more.
• Zone 1 – An atmosphere where a mixture of air and flammable gas, vapor, or mist is likely to occur during normal operations occasionally. This is further defined as more than 10 hours but less than 1000 hours per year.
• Zone 2 – An atmosphere where a mixture
The location of plant compressors layout poses particular risks, but that can still be overcome.
of air and flammable gas, vapour, or mist is not likely to occur in normal operation but, if it does occur, will persist for only a short period of time. This is further defined as more than 1 hour but less than 10 hours per year.
• Unclassified – Flammable mixture is present less than 1 hour per year.
Zones 0 and 1 would be roughly equal to Class I, Division 1. Zone 2 would be roughly equal to Class I, Division 2. Zones 20, 21, and 22 are for dusts with the second digit corresponding to Zones 0, 1, and 2 as far as likelihood of being present in the atmosphere.
Designations
When determining a hazardous area designation, the following things have to be considered:
A) Is the hazard a gas, vapor, mist, dust, or fibre?
B) What is the actual hazardous substance (gasoline, coal dust, sugar, etc.)?
C) How often will the hazardous substance be present?
D) How large of an area might it cover?
From that information, the classification can be determined using either the Class/Division or Zone methods. The degree of classification will determine the type of equipment that can be installed in that area.
There are a number of methods that are commonly used to protect equipment in classified areas. They are all designed to prevent the equipment from becoming a “source of ignition”. Commonly used terms include:
Explosion-proof – This term does not mean that the equipment is built in a manner that it will prevent it from exploding. Explosion-proof equipment is built so that if a flammable mixture enters the equipment and there is a source of ignition (spark, internal heat, etc.) the equipment will contain the explosion without damage and be able to cool the hot gases that escape the equipment to the point where they cannot ignite the flammable mixture outside of the equipment. This equipment must also be designed so that the exterior does not get hot enough during normal or abnormal operation to ignite a flammable mixture that might surround the equipment.
Intrinsically Safe
– Intrinsically safe equipment is equipment that does not contain enough energy to provide a source of ignition. Generally, this means that the equipment must be below 30 volts and
have a current of less than 300 mA.
Encapsulation – Some electronic devices can be encapsulated in a resin to protect them from explosive mixtures. Care must be taken to make certain that the device will not generate sufficient heat to either damage the internal components or the resin.
Purged or Pressurized –
An example of this would be a sealed electrical cabinet that maintains a positive internal pressure of inert gas, such as nitrogen, or clean air to prevent the ingress of a flammable mixture. Care must be taken with this type of system to ensure that the cabinet is purged prior to being energized.
Immersion – As the name implies, immersion involves placing the electrical equipment in a suitable liquid so that any flammable material in the atmosphere is not able to contact the equipment.
Hermetically Sealed – This commonly involves encapsulating an electrical device in glass, with its leads fused to the glass. Due to the possibility that the glass may break, this method cannot be used in Division 1 or Zones 0 or 1 locations.
Managing Costs and Risks
The goal of any facility that deals with hazardous materials should be to confine that hazard to as small an area as possible. This makes for a safer facility and minimizes the areas where equipment has to be modified at great expense to make it safe for operation. Modification of equipment to meet the requirements of classified areas can multiply the cost of that equipment two or three fold, and some equipment simply cannot be modified to meet those requirements.
In the case of air compressors, there are alternatives. In some cases, simply moving the proposed compressor installation location a
short distance into a better ventilated area can change the classification from Class I, Division 2 to being Unclassified.
The expense of 100 feet of piping will almost always be less than the modifications required to install the compressor in a classified area. In the case where the hazardous material is heavier than air, for example, siting the compressors up one floor may also change the location to Unclassified.
Or conversely, if the hazardous material is lighter than air, locate the compressed air equipment down one floor. Here’s another point to consider: having the compressor in an unclassified area improves the safety of the entire facility. A serious concern with compressors in classified areas is the possibility that they will pull in and transport flammable mixtures through the distribution piping into unclassified areas with other equipment not designed for classified areas.
In short, every effort should be made to locate compressors outside of classified areas. For both cost and safety, a little extra head work may reduce capital costs and improve safety.

DOW TO EXPAND ETHYLENE CAPACITY IN CANADA
Dow is incrementally expanding its Fort Saskatchewan, AB, ethylene facility by approximately 130,000 metric tons through the addition of another furnace and associated equipment.
The additional ethylene will be consumed by existing polyethylene assets in the region. The expansion cost of the facilities expected to be between US$200 million and US$225 million.
This project has received all regulatory approvals from Alberta Environment and Parks, the company says, and construction is underway. Facility construction and equipment installation will support an average of 700 jobs per year in Alberta, including indirect and induced economic activity. Start-up is anticipated to occur during the first half of 2021.

fortunately a slow one.
Here is an update on the process to date:
• First Ministers requested that the negotiation of the agreement be expedited;
• The reconciliation agreement is based on the mutual recognition of design reviews to: Reduce the number of CRN applications required to be submitted by manufacturers, and reduce the number of CRN design reviews needing to be conducted;
• Entered into force for participating jurisdictions on January 1, 2020;
• As of Jan. 1, 2020, the Reconciliation Agreement (RA) for CRN is in effect in British Columbia, Manitoba, Northwest Territories, Nova Scotia, Ontario, Prince Edward Island, Québec, Saskatchewan, and Yukon (Nunavut has indicated that it is intends to sign, but has not yet done so);
• Manufacturers need only have their design reviewed in one of these jurisdictions, and that review will be recognized as valid in the others;
• Pressure equipment must still be registered in each province or territory (P/T) where it will be used (This is to ensure that regulators remain aware of what equipment is approved for use in their jurisdictions);
• P/Ts still control their own design review and registration processes (mutual recognition means that there was no requirement to change these processes);
• Some P/Ts have arrangements to facilitate registration in other provinces and territories, but there is currently no common system;
• Work is underway to identify and pursue additional improvements in the efficiency of CRN de-
sign review and registration processes;
• Steering committee formed – PTAC, ACI (Association of Chief Boiler and Pressure Vessel Inspectors) and NPSAC (National Public Safety Advisory Committee);
• Steering Committee is working with P/Ts to develop clearer communications (a summary of the RA for CRN is available on the RCT website, https://bit.ly/3d4xiJ1);
• Steering Committee is working with P/Ts on investigating possible information-sharing solutions that may further improve and streamline review and registration processes for manufacturers; and,
•Steering Committee is working with P/Ts to explore development of other improvements such as a standardized/common application form.
Update on the CPCA AGM
In addition, the CPCA Executive is actively monitoring the ever changing COVID-19 situation. At press time, plans were to continue with the annual general meeting planned for May 28-31 in Whistler, BC.

CORONAVIRUS OUTBREAK LEADS TO HANNOVER MESSE 2020 POSTPONEMENT
The trade fair in Germany, Hannover Messe 2020, has been postponed from April to the week of July 13 to 17. Deutsche Messe AG is thus responding to global developments related to the Coronavirus.
Deutsche Messe made the decision to postpone Hannover Messe 2020 to July 2020 in close cooperation with the Hannover Region Health Authority, the Hannover Messe Exhibitors’ Council and the partner associations VDMA (German Engineering Federation) and ZVEI (German Electrical and Electronic Manufacturers’ Association).
The Hannover Region Health Authority had strongly recommended that Deutsche Messe follow the advice of the Robert Koch Institute, which includes comprehensive measures to safeguard health when hosting major events. For instance, fever measuring stations at all entrances and not allowing people from risk areas or those who have had contact with people from risk areas to enter the exhibition centre. This would have entailed a comprehensive evaluation of all trade fair participants — from exhibitors and visitors to service providers, exhibit builders and catering companies.
Deutsche Messe is unable to implement the proposed measures. In addition, their implementation would impair the staging of the event to such an extent that the event would not fulfill its purpose or would do so only with considerable restrictions for exhibitors and visitors.
Since the health of exhibitors, visitors, employees, and the public is the top priority for Deutsche Messe, the decision was made in consultation with Hannover Messe’s exhibitor advisory councils to switch to the July date.
Since 2001, Valve Accessories & Controls has built a reputation as a company comitted to quality products, and a commitment to service, second to none.

Sight glasses allow operators to see within their process vessels and pipelines in order to ensure optimal system performance. With humble origins dating back to the locomotive industry in the early 19th century, modern industrial sight glasses have become vital to process control… and for a good reason. Also called view ports, these critical pieces of process equipment offer a safe way to see the levels of liquids or gases that are traveling through a critical point of a design, monitor any pressure changes, and identify any harmful contaminants at early stages before they become a bigger issue.
When it comes to selecting a sight glass, there are a number of factors that need to be considered if the sight glass is to meet the needs of a specific operation. From how it’s mounted and gasket type, to choosing between an assembled or a fused sight glass, design engineers must be precise in their selection. However, nothing is more important than the selection of the glass itself.
While there are many different options to choose from when it comes to glass selection, the choice usually comes down to a decision between two types of glass: soda-lime or borosilicate. Which glass is the best choice for a particular sight glass will depend entirely on its application.
It’s important that the right glass is chosen… and that the glass is what it says to be. Recently, an inferior glass from an overseas supplier entered the North American market, claiming to consist of borosilicate glass and meet DIN 7081 standards. A chemical analysis of its material at a certified lab revealed this to be false. While it was presenting the glass as equivalent to the MAXOS gauge glass, this is not the case, leading to a serious safety concern. Additional testing also revealed that the glass counterfeits could not meet required threshold values for pressure and tension performance, meaning the glass is likely just soda lime glass rather than the borosilicate glass it claimed to be. This is a serious misrepresentation.
Choosing the wrong type of glass can quickly lead to a broken glass and site glass failure. Glasses can break from corrosion, being over-pressurized, from impact with operators or other process equipment, or from thermal shock, like when a cold wash down hits the sight glass on a hot vessel. If the contents of the hot vessel are pressurized, then a broken sight glass can lead to a jet of boiling liquid or steam and shards of glass flying at ballistic speeds. This type of breakage has been known to injure or kill operators on top of costly equipment damage, process downtime, and scrapped batches of products.
Soda-Lime Glass
Soda-lime glass, often used to manufacture bottles, light bulbs, and windows, is a common sight glass material due to how cheap it is. This type of glass is made from silica, soda, lime, magnesia and alumina. Together, these materials combine into a rather unremarkable glass that usually does little more than get the job.
There are two main types of soda-lime glass: annealed soda-lime and tempered soda-lime.
Annealed soda-lime is what’s used in drinking glasses and other common applications. As anyone who has ever dropped one of these glasses on the floor would know, annealed soda-lime is very easy to break. It’s also extremely susceptible to thermal shock, has poor chemical resistance, and limited operating temperatures, making it a horrible choice for critical applications. Be warned — many suppliers try to repair broken sight glasses with annealed soda-lime.
Tempered soda-lime refers to soda-lime that’s thermally tempered to have up to 10,000 psi of compressive stress at its surface, more than double that of annealed soda-lime. The tempered version is also more resistant to thermal shock. As such, tempered soda-lime is the only decent choice when considering soda-lime for sight glass applications. Unless stated otherwise, further mentions of soda-lime glass in this article will refer to its tempered version going forward.
Borosilicate Glass
Borosilicate glass, used to manufacture laboratory equipment and pharmaceutical-grade glass pipes, is increasingly becoming the go-to choice for sight glasses in more demanding applications. This type of glass is made similarly to soda-lime, but with a portion of the silica replaced by boric oxide.
Compared to soda-lime and other common sight glass options, borosilicate glass is more resistant to thermal shock due to its lower coef-
ficient of thermal expansion. It can also handle a greater range of temperatures and is significantly more resistant to corrosion and chemical attacks. When the risk of glass scratching or scuffing is higher, either from inside a process vessel or from the outside environment, borosilicate reigns supreme due to its better abrasion

resistance. Overall, borosilicate offers superior, industry-grade toughness and durability that can hold up to significant pressure and sudden impact conditions. This unmatched strength and integrity are why borosilicate glass is used in advanced products like the METAGLAS series of sight glass windows.
Beyond its higher safety and durability, borosilicate glass also offers better performance in what sight glasses are made to do — viewing inside a system. These glasses remain highly transparent, even when exposed to extreme temperatures or fluctuating process conditions.
Soda-Lime vs. Borosilicate
The advantages of borosilicate glass over soda-lime glass are clear. Overall, soda-lime, commercially known as BoroPlus, just can’t hold up to the superior qualities of borosilicate glass. However, in the name of efficiency, let’s compare them in greater detail to see when it’s okay to use soda-lime glass and when borosilicate glass absolutely must be used.
Quartz is an excellent material for thermal shock and steam. However, due to its brittle and often costly nature, it’s typically only used in applications where temperatures rise significantly higher than 500°F, such as in high-temperature steam applications. In fact, quartz can withstand temperatures as high as 1832°F when used properly.
Sapphire is the strongest and most resistant window but is generally not used in process observation equipment because it is expensive and cannot be molded and fused to metal. However, it can be used as a shield to protect a less resistant glass.
Due to its inferior thermal properties, soda-lime glass can only be used in applications where temperatures remain lower than 300°F. For any application that’s temperatures rise somewhere between 300° to -500°F, borosilicate must be used. Even if an application constantly stays under operating temperatures of 300°F, borosilicate glass should be specified in areas where hot equipment may experience washdowns with cool water. That’s because its higher thermal shock resistance will allow it to withstand the quick temperature functions that would cause soda-lime to break.
Borosilicate glass must also be used in any application that requires contact with caustic or acidic chemicals. Soda-lime is more likely to experience clouding and erosion in these scenarios. Even more, borosilicate glass meets the requirements of USP Type I and may be used with non-parenteral process media, such as with injectable drugs. Soda-lime, on the other hand, has more of a tendency to leach into the process media. After all, glass itself is a chemical compound that can, under the right conditions, react with different media, even water.
Borosilicate glass’ superior resistance is why it’s used in the MetaClamp LED Ring Light Series SGL, a powerful sight glass and system lighting combination.
Even though soda-lime glass is cheaper than borosilicate in the beginning, the total cost of ownership with soda-lime can creep up over the life of a sight glass operation.
Other Options and Considerations
While soda-lime or borosilicate glass will be the top contenders for glass selection in most applications, certain niche or high-level applications will call for another type of glass. Or, better put, another type of material entirely. This is referring to quartz and sapphire.
Unlike glass, in which its molecules are arranged randomly, quartz and sapphire are more technically described as crystals due to the rigid alignment of their atoms. This is the secret to their high durability.
Beyond extreme temperatures, sight glasses that have to deal with highly-caustic chemicals will also need special considerations beyond soda-lime or borosilicate glass. Chemicals like sodium hydroxide, hot concentrated alkaline solutions, phosphoric acid or fluorine are especially difficult on sight glasses. For applications involving these chemicals, it is necessary to protect the glass with a mica or Teflon film shield.
Making the Right Choice
Choosing the best type of glass for any viewing window will always depend on the specific application of the sight glass. While annealed soda-lime glass is almost never recommended, tempered soda-lime can hold up to certain less-critical applications. However, borosilicate glass remains superior in nearly every property and should always be chosen wherever possible over its soda-lime counterpart.

DRUM DUMPER FOR HAZARDOUS MATERIALS
Emerson has announced its ASCO series 353 pulse valve has been redesigned to help OEMs and end-users achieve a more effective, efficient and convenient bag cleaning. With a higher peak pressure, wider temperature range, patented quick mount clamp connection and overall part simplification, the series is said to provide longer bag and filter life and lower maintenance. Without optimum peak pressure, the company says, dust collector cleaning becomes inefficient and the consumption of compressed air rises. Because it hits peak pressure quickly, the valve series is said to create a more effective cleaning process. The design is also said to lead to improved airflow through the filter bags or cartridges for optimized dust collector performance while reducing costly compressed air consumption. Valve lifespan is over one million cycles on average. The new valve can be used in a wide range of applications, including concrete processing, grain, agriculture and feed, food processing, pharmaceutical, mining, rubber mixing/processing, metal processing, lime industry, cement factories and steel mills.

DUST EXTRACTOR GOOD FOR CLEANING AND SOURCE EXTRACTION
The DC 11-Module from Dustcontrol is a dust extractor which is made for source extraction of dust and chips and for cleaning. The dust extractor and the turbopump are mounted on a common chassis. The unit can be connected to a fixed pipe system. The machine can be used with turbopumps rated at 5 to 11 kW, with or without integrated control box and with several emptying alternatives such as sacks or containers of different volumes and other handling systems. It can be mobile with wheels or stationary, automatic or manual filter cleaning
and equipped with or without HEPA micro filter. The dust which is heavier than the air is forced against the walls of the cyclone by centrifugal force and falls down to the cyclone bas, where the outlet is. The air is forced to the middle of the cyclone and upwards through a fine filter. The filter is cleaned by a compressed air pulse or manually operated reverse pulse jet.

How the food industry can save time, money and resources on cleaning
By James Miller
Dust is a major issue in the food industry thanks to the presence of airborne allergens, which, while a problem for workers’ long-term health, can also pose issues further down the line for consumers.
Failing to undertake appropriate cleaning measures and tackling dust in hard to reach areas can affect product quality, while also running the risk of cross contamination — with potentially fatal consequences in the event of an extreme allergic reaction.
For the workers themselves, exposure to fine dusts from flour, cotton and pollens can cause inflammation of the airways, which can develop into infections such as bronchitis.
Overexposure to hazardous dust for a prolonged period of time can also cause permanent disabilities, and even death.
It is therefore essential that efficient measures are put in place within the food industry to ensure the protection of workforces and the quality of products, while adhering to the relevant health and safety regulations.
The food industry has special requirements and control of components and equipment used in production is extreme, with a special focus on migratory risk, surface finish and antistatic properties.
The new Dustcontrol Good For Food (GFF) process extraction and general cleaning range includes flap valves, suction brushes, flat nozzles, hose connectors, tubing system, joints, pre-separator, automatic shutter valves and filter units. Watch a video demonstration of GFF brushes at https://bit.ly/39qxmR8.
As a deeper understanding of the harmful properties of dust are better understood, businesses are taking steps to control and confine ar-
eas in the workplace where excessive dust is created, but the necessary cleaning required often takes a considerable amount of time, money and resources.
Research we carried out found that a third of UK food businesses spent between 11 and 20 per cent of their annual revenues on cleaning, with a further one in six claiming to spend even more than that.
On top of unnecessary costs, we also discovered one in four food companies spent more than 21 hours a week cleaning, while a third assess their cleaning processes at least once a week, on top of the time they spend actually cleaning.
It’s a snowball effect — not having the equipment to effectively capture dust at its source, both where and when it’s created, leads to an accumulation of dust, which in turn will naturally increase the time and money spent to combat it.
We understand how you strive for constant product quality and optimized costs. You are poised to meet your safety and quality requirements while optimizing resources and securing process repeatability.
100% traceability ensured with calibration services
CONSISTENT
Streamlining cleaning processes and using the optimum equipment for each scenario plays a large part in reducing time consumption, as well as unnecessary costs. Source extraction systems are one of the most effective ways of achieving safe and hygienic food production, as they are designed to ensure food processing areas are the cleanest they can be – keeping the potentially serious side effects of dust to a minimum.
With hygiene requirements within the food industry being extremely stringent, a complete source extraction system can be fully integrated into the production process for recycling or used as a centralized vacuum cleaning system.
Improve your plant availability, and ensure quality with optimized calibration
• Traceable on-site and laboratory calibration of various parameters
• We are a leading manufacturer of process instrumentation – uniquely qualified to calibrate
• Our global, harmonized calibration standards provide consistent service quality
At Dustcontrol, we’ve just launched a new Good For Food (GFF) process extraction and general cleaning range that, when integrated with our GFF components, includes flap valves, suction brushes, flat nozzles, hose connectors, tubing system, joints, pre-separator, automatic shutter valves and filter units. All material is approved for food contact and several have been designed to be installed in Zone 22, according to ATEX Directives 2014/34/EU.
By combining safe food contact, autoclavable, colour-coded, detectable, anti-static and FDA compliant properties to fully integrate a comprehensive system, food processing companies can yield higher quality products, whilst making savings on factory-wide cleaning costs.
Overall, cleaning is a serious business in the food industry, courtesy of strict process and control. With companies spending considerable amounts of time and money on cleaning, it pays to make sure they’re doing it right. Streamlining cleaning processes and using the optimum equipment ensures businesses are utilizing resources and saving valuable time and costs on creating a safer working environment.

This picture was shot through my front window. Spring must be just around the corner when the deer are getting restless.
As I write this the Coronavirus is in full swing. Unprecedented actions are being taken to protect each other. For the first time in the 45 years running the Process & Automation Shows we have postponed some of them. The Mississauga and Sarnia shows in Ontario have been postponed until the late fall. Keep an eye on our web site and emails from us about the new dates. We are making a decision about the Saint John, NB, show as we go to press. The rest of our editorial and advertising services will continue normally. If there’s a silver lining to this situation it is that people are cooperating with the direction given by authorities. (Except for the toilet paper and hand sanitizer hoarders). So hopefully we can put the Coronavirus behind us for good before too long.
Our next issue, June will feature our Focus on Maintenance & Safety. Editor Mike Edwards’ supplement will cover all things to do with Sensor Technology. The issue closes May 1st and will mail a month later. If you have something you’d like to submit get it to us by mid-April.

DIRECT-TO-CLOUD AREA GAS MONITOR
Blackline Safety has announced the G7 EXO, said to be the industry’s first direct-to-cloud, drop-and-go area gas monitor with an unprecedented battery life of over 100 days. The monitor is designed to withstand the harshest of conditions, addresses the challenges of traditional systems by introducing 4G cellular and satellite connectivity to deliver a user-friendly, long-lasting solution, the company says. Select customers and partners are now conducting field trials in oil and chemical terminals, fence lines and perimeters, spill sites, drilling rigs and facility maintenance projects. With a run time of over 100 days for a four-gas configuration, the gas monitor can save hours in traveling from a jobsite to another location to change batteries. While traditional area gas monitors require users to establish a mesh network that requires line of sight between monitors, the G7 EXO offers instant connectivity when powered on, it explains. Mesh networks are also said to be vulnerable to communications interruptions and limit the number of devices as well as the service area range.
