Polyol Ester (POE) oils
Polyolester oils, or POE oils, constitute the second generation of lubricants which were developed for use with HFCs. POE oils are excellent lubricants which are less hygroscopic than PAG variants and chemically more stable that PAG types when in the presence of water. POE oils are intended for use in all refrigeration and air conditioning applications.
Poly-Alfa Olefin (PAO) oils
Poly Alpha Olefin oils - or PAO oils - can be described as 'mineral synthetic oils' because of their identical structure to traditional mineral oils, the only difference being that they are formulated from monomers. PAO oils can be used in refrigeration systems working in extreme conditions, thanks to their low pour points and excellent thermal stability.
Poly Alkylene Glycol oils - or PAG oils - were the first oils developed for use with HFC refrigerants and are perfectly miscible with these products, however they are very hygroscopic. PAG oils are mainly used in copper-less air conditioning systems using R134a, because of their tendency to absorb water and their incompatibility with copper. Being perfectly miscible with ammonia, PAG oils were adopted in refrigeration systems using this refrigerant.
Refrigeration equipment using ammonia often requires a specific type of oil to ensure correct operation. We offer these two commonly used hydro-treated oils for ammonia applications.
Alkyl Benzene oils
Alkyl Benzene oils types were the first synthetic oils to be used in the refrigeration industry. They are thermally and chemically stable, and are perfectly miscible at low temperatures. AB oils are recommended for use with refrigerants such as R22 and HCFC blends. They are compatible with all traditional mineral oils which they can replace where the system malfunctions with the original lubricant.
Oils for CO2
As popularity for alternative refrigerants grows, Climalife have on offer oils especially compatible to work with CO2 equipment installations.
We offer a particular oil designed by Mobil especially for applications using ammonia.
Mineral oils used for the lubrication of refrigeration compressors are mixtures of hydrocarbons without wax, especially selected for their excellent fluidity at low temperatures. This kind of lubricant is particularly suited for use with CFC, HCFC refrigerants and ammonia.
