It is crucial for companies to stay informed about industry issues and trends While other industries may be slowing down, for us in HVAC&R it is hectic. It is not uncommon for our industry to maintain steady or even experience increased demand during economic downturns. This is often because the need for climate control and refrigeration remains essential across various sectors.

In a recent trip to Christchurch, our CEO Gina McMaster spoke to companies at the Aotea Group conference. This was a great platform to showcase our expertise in the HVAC&R industry and to engage with other industry professionals to understand the challenges they’re facing.

RLNZ has just released its LinkedIn newsletter ‘Learn about HVAC&R training’. This is where you can find out about what training is available and what standards and legislation you should know about.

It is a free monthly newsletter and features training updates and events from the HVAC&R industry in New Zealand.

“As awareness of environmental concern grows, there is greater emphasis on energy-efficient HVAC&R systems, driving demand for upgrades and replacements.”

Each year, March 8 celebrates International Women’s Day. To inspire inclusion – this year’s global theme – IRHACE sat down with three women leading the way in the HVAC&R industry to hear their experiences and advice for others. Our Women of IRHACE group focuses on delivering messages, coordinating stories and content for the Industry Journal and to increase the number of female members in IRHACE. In this issue, IRHACE councilor Chris Arvidson talks about the risk of buying illegal refrigerants and RLNZ’s recommendation to only purchase refrigerants from reputable suppliers. We are substantially disheartened when we see individuals blatantly offering these products at reduced prices, indicating that they are not paying carbon taxes in line with ETS requirements – offering them to the general public who do not have the training, knowledge or equipment necessary to handle them safely.

Celebrating women in HVAC&R To inspire inclusion, IRHACE sat down with three women leading the way in the HVAC&R industry to hear their experiences and advice for others International Women’s Day on March 8 each year is a celebration of women’s achievements worldwide. This year, the campaign’s theme was to Inspire Inclusion – emphasising the importance of diversity and empowerment in all aspects of society.

It’s a theme that underscores the crucial role of inclusion in achieving gender equality. It calls for action to break down barriers, challenge stereotypes and create environments where all women are valued and respected.

This year to inspire inclusion in the HVAC&R industry, IRHACE sat down with three inspiring women to learn more about their roles, journeys and experiences in the sector, and how other women can make the most of a career in the industry.

PIP STRICKLAND

REGIONAL SALES MANAGER AT REFSPECS What advice do you have for women starting out in the HVAC sector today?

I have been involved in the HVAC&R industry for nearly 15 years now, with the past eight years being part of the fantastic, diverse team at Refspecs. Similar to many individuals, I stumbled into this field without prior knowledge. It’s an industry that everyone utilises, but it isn’t widely recognised.

Navigating through a predominantly male oriented industry as a woman can pose initial challenges in gaining acceptance and overcoming certain stereotypes. However, like any field, dedication and time investment in learning can outweigh any struggles.

Engaging with other women in our profession, networking, learning and addressing challenges has also proven invaluable.

“For women considering entering this fantastic profession, I recommend attending industry events to connect with the inspiring individuals who contribute to the excellence of our field.”

- Pip Strickland

How can others mentor and empower women to succeed in the sector?

The refrigeration and HVAC sector boasts numerous successful women, including company owners, engineers and salespeople, whom I greatly admire. For women considering entering this fantastic profession, I recommend attending industry events to connect with the inspiring individuals who contribute to the excellence of our field.

“All apprentices need to work with more experienced technicians who are willing to take the time to train them and ensure they have a full understanding of what they are doing and how things work.”

- Lisa Stoneham

LISA STONEHAM

SERVICE COORDINATOR AT ABC PUMPS What advice do you have for women starting out in the HVAC sector today?

It is a great industry if you apply yourself. Don’t be afraid to jump in, ask questions and give things a go. You don’t become a good technician without making mistakes.

Is there anything you’d like to see change in the industry to encourage more women to start a career in HVAC?

Have you had any key mentors in your career? Can you share a little about them and how they’ve guided you?

It is a common misconception that HVAC and refrigeration technicians are just electricians.

As it becomes more common knowledge that they are separate, specialised trades, more people will be interested in joining.

I started my refrigeration apprenticeship in early 2012 and have had some great mentors along the way, but it all started with Michael Jowett. I met Michael on the first day of my apprenticeship and he was the main technician I worked with for the first two years of my apprenticeship. My first day was replacing a compressor on a supermarket rack system. Michael took the time to explain everything, the different components, how they worked and made sure I understood what I was doing and why.

The key is showing people the broad range of work available under the HVAC&R umbrella. It’s not just cleaning filters and checking temperatures.

I was very fortunate during my apprenticeship and I worked with an amazing team of technicians who were always willing to help and answer questions.

How can others mentor and empower women to succeed in the sector?

I don’t think it is just women; all apprentices need to work with more experienced technicians who are willing to take the time to train them and ensure they have a full understanding of what they are doing and how things work.

“Be humble, acknowledge your privilege and advocate for the rising stars around you.”

- Sarah-Jayne Cook

Having someone I can confide in and seek advice and guidance from has been pivotal for my career. My mentor has listened, guided and challenged me, and probably most importantly, has sponsored my progression. It’s not what people say about you while you’re in the room, but what they say and do to actively promote you when you are not present that will have a meaningful impact. To have someone who believes in you wholly and has all the qualities required to successfully advocate for you is a true gift, one for which I am extremely grateful.

SARAH-JAYNE COOK

PRESIDENT OF THE INSTITUTE OF REFRIGERATION (IOR) What advice do you have for women starting out in the HVAC sector today?

Network, network, network! When I started my career almost 24 years ago, my support network was very much limited to my place of work; we simply were not blessed with all the fantastic online platforms we have today. While the number of women working in HVAC has remained relatively static, online platforms have brought our communities together allowing us to connect with other women working in our field, amplifying our voices, and growing our collective influence. With our online platforms and subsequent networks, I really feel like I have found my tribe – like-minded women who actively build other women up!

I would recommend joining the International Women in Cooling (INWIC) community through their website, and the Women in Cooling LinkedIn group as a starting point. You never know where these connections may lead you and the breadth of knowledge you will gain from them.

Have you had any key mentors in your career? Can you share a little about them and how they’ve guided you?

I have been lucky to have been supported and encouraged by several incredibly inspiring people throughout my career to date, but the most significant is my current mentor. I like to think our connection was made through a shared passion for cooling and building a better environment for everyone to thrive in. It has never been a formal arrangement, but more a friendship that has grown into mentorship and sponsorship over the last eight years.

How can others mentor and empower women to succeed in the sector?

Just as I have a mentor and sponsor, you too can offer the same for your colleagues and network.

It is one thing to walk through the doors of opportunity, but it takes a true leader to hold that door open for those who follow behind. Be humble, acknowledge your privilege and advocate for the rising stars around you.

In practical terms, nominate your up-and-coming talent for projects and promotions, sing their praises where they are due, offer up opportunities to lead or present, and support them fully through the process. Whether you are a mentor or mentee, it takes long-term commitment, listening, sharing your knowledge and experiences, being respectful and ensuring confidentiality on both sides.

Is there anything you’d like to see change in the industry to encourage more women to start a career in HVAC? Beyond wider culture change, role models are vitally important in attracting fresh talent. After all, ‘you cannot be what you cannot see’. Role models make our goals tangible. Seeing others succeeding and pushing for their work to be the best it can be inspires us to do the same. Support and encourage those around you to shine as the strong role models you know they are.

Good role models will motivate their teams to do their best to excel at work, will lead by example, provide valuable career insights, and will help others to set realistic goals and plan for professional development. Ultimately, they will act as beacons for other women considering a career in HVAC.

Energy efficient, updated product ranges for Fujitsu

Reflecting the brand’s ongoing commitment to lowering the global warming potential (GWP) of its products, improved energy efficiency and design improvements have been introduced in Fujitsu General’s expanded R32 heat pump and air conditioner ranges irhace.org.nz

MARCH 2024

Refrigerants play a vital role in the operation of air conditioners, and recent developments in refrigerant technology have focused on lowering its GWP. “R32 refrigerant offers a 67 per cent lower ‘global warming potential factor’ compared to the commonly used R410A refrigerant,” says Kyle Rafter, Fujitsu General head of product ANZ. This means R32 offers equivalent air conditioner performance with reduced environmental impact – seeing Fujitsu embrace this in its wide range of R32 products, including wall-mounted, floor console, ceiling console, ceiling cassette and ducted options.

Fujitsu General has launched two updated heat pump/ air conditioner ranges and a new wired controller that reflects the brand’s commitment to innovative design and energy-efficient climate control. These include the new R32 Ceiling Console range, the R32 Circular Flow Cassette range, and the Kagami wired controller.

The updated Ceiling Console range, designed with an elegant, gently curved aesthetic, suits any room setting.

It features nine outdoor models, ranging from 6.0kW to 15.5kW in heating capacity (six single-phase models from 6.0kW to 15.5kW and three units in three-phase from 11.2kW to 15.5kW heating capacity).

Suitable for New Zealand’s climate, both ranges can operate from -15ºC in heating mode and up to 50ºC in cooling mode. The new models have a range of energy-saving features such as ‘economy mode’, which allows the unit to adjust the temperature by 1ºC to allow for a reduction in power. Both ranges have a set of timer functions to enable the user to set when they wish their units to be turned on and off.

The R32 Circular Flow Cassette range has an optional ‘human sensor’ feature. This intelligent feature detects the movement of people to deliver optimum efficiency

and temperature control. When in operation, if the sensor detects no movement in a room after 20 minutes, the unit will automatically switch to energy-saving operation, modifying the temperature to minimise energy consumption. When movement is detected within the room, the unit reverts to its previous setting.

“Both ranges offer an improved heating capacity in low outdoor temperatures,” says Kyle.

As well as the brand’s updated heat pump and air conditioner ranges, Fujitsu’s latest innovation to climate control is the award-winning Kagami wired controller.

The mirrored design of the Kagami controller blends seamlessly into any space, with its sleek design awarded the 2022 Good Design Award. It was also a finalist for the 2023 IDEA Award.

“Kagami has an intuitive touch screen that can be operated by swiping vertically and horizontally to give you complete control of your comfort. The controller’s operation mode is displayed via LED light colours and can be switched off overnight to avoid glare,” says Kyle. “The controller will display specific sensor values on a select range of outdoor and indoor units for maintenance and service support.”

These product innovations demonstrate Fujitsu’s dedication to actively pursuing activities to conserve energy and natural resources, including the practice of reducing, reusing and recycling.

“As a waste reduction measure, the new R32 Ceiling Console and R32 Circular Flow Cassette range no longer come with an included controller as these are often ordered as part of a commercial project and many controllers were not being utilised. Instead, customers can now select whether they want a wired or wireless controller or the unit by itself, ultimately reducing waste.”

The importance of HVAC&R exhibitions

Trade exhibitions are one of the most successful platforms for accelerating industry knowledge and business growth within the HVAC&R and building services industries across New Zealand and Australia “Heat pump technology, especially when integrated with renewable energy sources, has a substantial environmental impact, emitting far less greenhouse gas than traditional HVAC&R systems,” she says.

“Particularly in Australia with the Victorian and ACT governments banning new gas connections and other states likely to follow, electrification is driving industry change. This, coupled with climate change, has accelerated the use of heat pumps and technological advances.”

Amanda Searle, CEO at ARBS. While New Zealand has the upcoming HVAC&R Hub to look forward to in June, Australia’s HVAC&R sector benefits from the Air Conditioning, Refrigeration & Building Services (ARBS) Exhibition – a showcase of the latest cutting-edge innovations and new products and technology from around the world.

“Exhibitors invest significantly in their stand design and construction, creating impressive, engaging, informative and innovative displays,” shares Amanda Searle, CEO at ARBS. “We’ve seen exhibitors transport massive pieces of equipment from overseas, allowing visitors to experience the latest products and designs firsthand.

Exhibitors come from every corner of the globe with around 12 per cent of the floor space dedicated to international exhibitors, offering a unique opportunity to experience global-leading innovations, products and technologies.

“I’m also looking forward to attending IRHACE’s HVAC&R Hub at BuildNZ to gain insights into the New Zealand market and observe how the sector is evolving there.

This will provide a valuable comparison and potentially uncover new opportunities for collaboration and innovation.”

Trends to expect at upcoming HVAC&R exhibitions Heat pumps are a significant trend that Amanda expects to see at upcoming exhibitions including ARBS and HVAC&R Hub, driven by the electrification of heating systems to replace fossil fuel-based systems in buildings.

MARCH 2024

Another trend expected to be widely discussed is artificial intelligence (AI).

“Transforming the future workforce, smart buildings, automation and intelligent building management are progressing rapidly, with AI poised to accelerate these technological advances further.”

Maximising ROT when participating in HVAC&R exhibitions Many will agree that for those exhibiting at trade events, the most effective strategy for maximising ROI involves having the right personnel on the stand.

“Customer-focused staff who are knowledgable about the company’s products and can provide valuable advice about selecting appropriate products are crucial,” says Amanda.

“Ensuring timely follow-up on all leads is also critical.”

ARBS 2024 takes place in Sydney from May 28-30.

HVAC&R Hub will be at Auckland Showgrounds from June 25-26.

Understanding AHRI Standard 700, the benchmark for reclaimed refrigerant A-Gas has published a new white paper exploring the importance of understanding what AHRI Standard 700 specifications are and why they are important Under the Kigali Amendment of the Montreal Protocol, the global phasedown of the production, import and hydrofluorocarbons (HFCs) has begun.

To meet its domestic and international climate change targets, New Zealand introduced its Emissions Trading Scheme (ETS). The ETS, together with the international HFC phasedown, has put significant pressure on the supply of legacy HFC refrigerants. This will particularly be the case in the coming years as there are substantial step-downs in the available quota to import refrigerants in addition to an expected increase in the value of refrigerants due to the ETS. This reduced availability and increased value of HFCs in New Zealand has led to an increase in the practice of re-using refrigerant recovered from existing systems.

Re-using recovered refrigerant without sufficient testing and reprocessing introduces the potential risk of

irhace.org.nz

MARCH 2024

equipment damage and poor efficiency from non-certified or untested, low-purity refrigerants.

Reclaimed refrigerant, on the other hand, is recovered refrigerant that undergoes thorough chemical analysis, cleaning of contaminants and reprocessing before re-entering the market in line with the equivalent virgin product standard AHRI 700.

Refrigerant reclamation is an essential part of Lifecycle Refrigerant Management (LRM), an effective and deliverable circular economy solution that can help the industry transition to lower global warming potential (GWP) alternatives and reduce emissions. LRM focuses on avoiding leaks, promoting refrigerant recovery and increasing reclamation rates to mitigate unnecessary virgin refrigerant production and emissions.

The code of practice prepared by the Institute of Refrigeration, Heating and Air Conditioning Engineers of New Zealand (IRHACE) and the Australian Institute of Refrigeration Air Conditioning and Heating (AIRAH) for Australia and New Zealand states that for refrigerant to be re-used in a system other than that from which it was removed must be tested and, if necessary, reprocessed to ensure it complies with the AHRI Standard 700. Given its inclusion in the code of practice, and as reclaimed refrigerant becomes an increasingly essential part of the supply mix, it is important for all stakeholders in the industry to understand what AHRI Standard 700 specifications are and why they are important.

It is also important for the industry to support the demand for AHRI700 standard reclaimed refrigerant, along with the significant capacity to process this recovered refrigerant back to AHRI Standard 700 specification. Encouraging the industry to make the most of the products we already have in installed systems is key to increasing the circularity of the HVAC&R industry, as well as ensuring supply continuity of diminishing legacy refrigerants.

What is the AHRI Standard 700?

The AHRI Standard 700 Specifications for Refrigerants is a globally recognised standard that stipulates the ‘acceptable levels of contaminants (purity requirements) for fluorocarbon, hydrocarbon, and carbon dioxide refrigerants regardless of source’. The standard also lists acceptable test methods by which to analyse refrigerants.

The purpose of this standard is to establish purity specifications, verify composition, and specify the associated methods of testing for acceptability of the refrigerants including CFCs, HCFCs, HFCs, HFOs and hydrocarbons. The specification and test methods are relevant to all refrigerants for use in new and existing refrigeration and air-conditioning products within the scope of AHRI and regardless of source whether it is new, reclaimed and/or repackaged.

The Australia and New Zealand Refrigerant Handling Code of Practice 2007 (Part 2) Systems Other Than Self-Contained Low Charge Systems, published by AIRAH and IRHACE, which came into force on 1 January 2008, states that: ‘Refrigerant must be either disposed of or tested when it is suspected to be contaminated or is to be re-used in a system other than that from which it was removed. If necessary, it may be recycled or reprocessed to ensure it complies with the provisions of ARI 700-2004 (AHRI standard 700)’.

15

Why is AHRI Standard 700 so important?

As reclaimed refrigerant becomes an increasingly important part of the supply mix, it is vital that these refrigerants conform to AHRI 700 standards to ensure that products meet international quality standards and are fit for purpose.

At A-Gas, we have state-of-the-art separation technology and laboratories that enable the reclamation processing and quality testing of used refrigerants, returning and certifying them back to virgin grade AHRI 700 standards.

Using quality reclaimed refrigerants that meet AHRI 700 standards provides peace of mind for servicing contractors and system owners that critical systems will perform as efficiently as possible, reducing the potential risk of system damage and costly system repairs due to poor-quality refrigerants.

The quality of refrigerant and oil in a live system has a significant impact on its efficiency and lifespan, factors that impact not only the bottom line but also our environment.

It has been shown that moisture and acid contamination can cause corrosion and copper plating on components such as crankshafts, compressor casings and oil pump assemblies. The presence of particulate contamination can lead to system damage.

If the refrigerant purity is lower than standard, system operating efficiency and capacity can be reduced. This in turn can lead to increased energy use and reduced equipment life. For contractors, it is a significant risk to be introducing into a customer-owned system.

How can you ensure your reclaimed refrigerant is compliant?

Testing recovered refrigerant to determine its level of conformance to AHRI standards for potential re-use is an important first step. If tests show that the refrigerant does not meet allowable purity or contaminant levels, having the refrigerant reclaimed to remove contaminants and adjust purity is required. The reclamation process can include processing the used refrigerant through filters, dryers, non-condensable gas removal equipment and separation/distillation, to return it to virgin grade specification. All AHRI quality parameters are then verified using the analytical methods prescribed in the AHRI standard to determine whether the reclamation process has been successful and whether the refrigerant is fit for re-use.

An additional benefit to understanding the quality of refrigerant running through a system is that it allows for the diagnosis of potential issues for system owners and assists contractors in understanding a baseline for future work to be carried out.

This is where A-Gas supports the industry, servicing contractors and end users with full analytical testing capability in addition to processing the recovered refrigerant back to AHRI 700 certified product.

Increasing refrigerant reclamation rates is an essential part of effective Lifecycle Refrigerant Management, a practical and economically viable approach that can help the transition to lower GWP alternatives and reduce emissions.

Reclaimed refrigerant that conforms to AHRI 700 standards reduces the need for virgin refrigerant production, embraces the principles of the circular economy and helps to reduce the HVAC&R industry’s environmental impact.

As the industry increasingly becomes reliant on the supply of reclaimed refrigerant to meet demand, ensuring the use of AHRI 700 reclaimed refrigerant reduces the risk of potential equipment damage and poor efficiency from non-certified or untested, low-purity refrigerants.

A-Gas’ capability in New Zealand, together with its global leadership in lifecycle refrigerant management offers the local market access to AHRI standard reclamation and testing along with safe and efficient refrigerant recovery and low global warming refrigerant alternatives.

Making the most of your CPD

With online learning and in-person events, it’s easy to manage your professional development and make the most of your training.

There is an increased need for CPD (Continuing Professional Learning) points as compliance grows across the HVAC&R industry, and maintaining a set number of points is required to keep certifications and qualifications current.

Thankfully, there are many avenues to take in order to gain CPD points.

“Of course, we offer online learning, webinars and so forth. Individuals can study in their own time and at their own pace. When they’ve got time to fit something in, they can make the most of their downtime for training,” says Matt Birch, RLNZ chair and regional training manager for BDT (Black Diamond Technologies).

“There are many different subjects available as we get more and more online. You may have a particular interest in ducting, filtration or airflow and be able to look at training in that area of interest. That enables you to learn and develop at the same time.”

CPD points are also available when attending face-to-face training and site visits, such as the recent technical site visit to Silver Fern Farms. Events such as this allow members to network with other like-minded people, opening business opportunities.

A new laboratory for refrigerant quality testing has opened in New Zealand

The first laboratory in New Zealand with the capability to test the quality of refrigerants against the globally recognised AHRI Standard 700 is now operational

Refrigerants that conform to AHRI Standard 700 meet international quality standards on moisture and purity specifications that ensure they are fit for purpose when used in vital refrigeration and cooling systems.

“This is why we’re extremely pleased that we can offer our laboratory and analytical services to help customers optimise the performance of their assets and avoid unnecessary costs in system repairs.”

A new laboratory at the A-Gas site in South Auckland is the only facility in New Zealand that can offer customers comprehensive testing and analysis of refrigerant quality, enabling proactive diagnosis of potential issues for system owners and assisting contractors to understand a baseline for future work to be carried out.

The capability of the A-Gas laboratory comes at a vital time as reclaimed refrigerants become an increasingly important part of the supply mix due to significant step downs in hydrofluorocarbons (HFCs) importation.

Re-using recovered refrigerant without appropriate testing and reprocessing introduces the potential risk of equipment damage and poor efficiency from non-certified or untested, low-purity refrigerants.

“Refrigerants that are unable to meet important AHRI conformance specifications such as purity and acidity are at risk of causing poor system performance and efficiency, consequently contributing to potential system deterioration,” says Mitch Williamson, country manager for A-Gas New Zealand.

The new laboratory will play a major role in supporting the industry, servicing contractors and end users with full analytical testing capability in addition to recovering refrigerant from the market and processing it back to AHRI Standard 700 quality.

The risk of buying illegal refrigerants With a growing occurrence of refrigerants being listed for sale online, it’s important to understand the importance of buying from safe sources – and the dangers associated with purchasing from illegal sellers There are hefty fines and risks to health and safety for installers and users when working with illegally-purchased refrigerants.

Environmental impact: Risks such as refrigerant leakage into the atmosphere increase even further with the use of inadequate cylinders.

Health and safety impact: Refrigerants fall under ‘dangerous substances’ and need to be handled with care, even more so with the increased use of flammable and high-pressure gases. Refrigerants that do not comply with the gas producers’ specifications or with the content indicated on the cylinders can pose a serious risk for the health and safety of installers and users.

Unfortunately, despite the risks, refrigerants have been appearing online.

Financial impact: High fines or even criminal prosecution can be involved with the illegal sale of refrigerants.

Operational impact: Refrigerants that do not comply with specifications (impurities, contamination with oil and other substances, etc.) can lead to bad performance of equipment, leading to loss of capacity, reduced energy efficiency, higher operational cost, equipment failures and more.

Business impact: In turn, this can lead to the deterioration of relationships with customers and reputational damage as a result of equipment issues.

“The importation of the refrigerant R404a into New Zealand is controlled via the ETS scheme and carbon taxes are applied at the point of sale. All quantities are recorded and monitored through recognised wholesalers and via the ETS scheme. Selling the products outside of regulated arrangements contravenes the regulations above and the Health and Safety at Work Act 2015, and additionally undermines everything this industry works so hard to achieve including the reduction of our national carbon footprint,” says Chris Arvidson, IRHACE Council member.

“We are substantially disheartened when we see individuals blatantly offering these products at substantially reduced prices.” - Chris Arvidson

“I believe our industry takes its responsibility for refrigerants and the damage they do to the atmosphere very seriously and we have, over the last few years, developed training modules with input from Worksafe to provide compliance with New Zealand regulations and legislation.

“We are substantially disheartened when we see individuals blatantly offering these products at substantially reduced prices, indicating that they are not paying carbon taxes in line with the ETS requirements, and offering them to the general public who do not have the training, knowledge or equipment necessary to handle them safely.”

How can you identify illegal refrigerants?

Under the Health and Safety at Work (Hazardous Substances) Regulations 2017, anybody handling or recovering compressed gases must have had suitable training and hold an Approved Filler Test Certificate.

Most refrigerants currently used in New Zealand are classified as compressed gases under the Health and Safety at Work (Hazardous Substances) Regulations 2017. Some refrigerants currently used in New Zealand such as propane and butane are flammable and hazardous substances under the HSNO Act. Therefore, nearly all users of refrigerants are required by legislation to hold an Approved Filler Test Certificate.

How do I get an Approved Filler Test Certificate?

RLNZ provides an Approved Filler courses for both A1 and A2/A2L refrigerants which is required by the HSNO 2004 Compressed Gas Regulations and is the minimum legal obligation for anyone working with refrigerant.

You can obtain a new license or renew your existing license by learning current information for A1 and A2/A2L refrigerants and passing a practical assessment using current materials and fit for purpose technology. Learn more here rlnz.org.nz/w/rl/courses/cat-43-approved-filler

Always purchase refrigerants from reputable suppliers RLNZ recommends only purchasing refrigerants from reputable suppliers such as: • • • • • • •
