Lubrication oils to prevent leaks Ignasi Pi Ferrer* discusses how new lubricants can detect and prevent leaks, as well as improve machine longevity.


security risks for employees and harm to the environment. Oil leaks can be caused by problems such as inadequate assembly, adverse conditions, unsuitable maintenance practices and excessive vibration or abrasion. It is important to detect leaks as quickly as possible, so that it can be stopped in time and the production of the machine can be optimised. Therefore, Cromogenia Units developed a lube oil called TADALSINT LUB 280 to prevent oil leaks within IS and rotating machines. This product contains an ultraviolet tracer, which detects leaks or excessive lubrication. This leads to better control over lubrication consumption. TADALSINT LUB 280 should be used for centralised systems (IS and rotating machine lubrication). The lube oil is diester and poly alpha olefin based. It is also supplied with viscosities from 220 to 250cSt at 40°C, which is the greasing frequency circa every 60 minutes (all greasing frequencies for IS and rotating machines depend on the working conditions). Regarding IS machines, frequencies also depend on whether the feeder and the machine itself belong to a centralised system or not.


Machine longevity

If oil leaks within IS machines are not detected, it can cause considerable economic losses for businesses. Undetected oil leaks can lead to huge financial costs at the end of the year. It can also cause poor machine performance,

The company also developed a lubricant called TADALGLAS A 125 MHL, which is a soluble oil for drop shearing. It is semi-synthetic, an ecological type and based on diester compounds. According to the company, this shear lubricant

panish company Cromogenia Units has developed a lubrication oil after clients such as Saint-Gobain, Verallia, NSG Pilkington, Vidrala and Vicasa experienced uncontrollable oil leaks in their IS Systems. The company’s Department of Metalworking decided it would have to develop a new product in order to optimise costs and results. This department is in charge of industrial lubricants and process products, including oils and greases. It develops and manufactures specific products for glass, aluminium, copper drawing, fine die-cutting, different metal forming operations, sintered products, automobiles and mining. With more than 75 years of experience, Cromogenia has always provided technical assistance to its customers. They use periodical analysis to describe the oils’ status and properties. This includes lubrification studies and reports to improve greasing frequencies, the environment and reduce consumptions. In addition, the company’s audit service for preventative maintenance includes temperature analysis of the mechanisms involved and their vibration frequencies.

is high performing for sophisticated spray systems and is to be used for low concentrations. The product also solves the foaming tendency in soluble oils. Cromogenia offers maintenance lubricants for general services, which makes usage simpler. It also optimises greasing and oil changing frequencies. The lubricants are long lasting and environmentally sustainable, which means that less product can be used. The advanced technology of the product also increases the lubrication frequencies, as high intervals can be used. As they are specific products, there are fewer maintenance stops, which are caused by leaks and clogged filters. This category includes oils for gears, gearboxes, speed shifters, torque converters, hydraulic circuits, cushioning circuits, compressors and turbines. Cromogenia ensure that the IS rotating machines are greased correctly, because frequencies tend to become increased in centralised systems. This leads to less consumption and contamination, as well as better lubrification; which leads to a significant economic decrease. The company’s oils for funnels and swabbing references allow for longer dosing to glass producers. They are used in small proportions, which are diluted in water (about 0.1%) for centralised systems or micro-pulverisation (hollow glass). Cromogenia also focuses on greases to be used in bearings, fasteners and other applications for hollow and flat glass. They are long lasting, which means that they allow longer greasing frequencies and a high yield, along with less damage. This is especially true in terms of bearings and mechanisms subjected to extreme pressure and high temperatures. These include lithium complex, calcium sulphonate, polyurea, inorganic thickener and synthetic PAO based greases. �
