Miscible CO2 refrigeration compressor fluid This product is a premium lubricant that has been formulated specifically for use in CO2 refrigeration systems. The advanced formulation will provide superior miscibility and lubricity in high pressure CO2 systems. It will also offer excellent chemical and thermal stability, excellent low temperature fluidity, and a very long service life. The product is based on double end capped technology.
The development of trans-critical CO2 systems requires speciality lubricants due to the high pressure and subsequently higher loading on bearings. The majority of conventional lubricants such as mineral oils and alkylbenzenes are not soluble with CO2. Polyol ester (POE) synthetic lubricants show good miscibility properties, however this can result in a dramatic reduction in lubricant viscosity. PAGs show partial miscibility with CO2, however the viscometric properties of polyalkylene glycols remain unaffected and the decrease in viscosity observed with POEs is not observed for PAG’s under CO2 dilution, thus good wear protection properties are retained with PAG’s.
