ArChine Cotoo POE 85
Refrigeration Oil for CO2 Compressors
 
PRODUCT DESCRIPTION
ArChine Cotoo POE 85 is unique custom blend of synthetic Polyolester(POE) with additives for excellent wear protection, oxidation stability and lubricity. ArChine Cotoo POE 85 has an excellent solubility/miscibility with the refrigerant carbon dioxide (R 744).
 
ADVANTAGES
    High thermal stability
    High chemical stability with CO2 refrigerant
    Excellent miscibility with CO2 – also at low temperature
    Outstanding deep-temperature flowability
    Excellent lubrication at high pressure levels under CO2 atmosphere
 
APPLICATIONS
ArChine Cotoo POE 85 is developed for use mainly in refrigeration systems which are working with the refrigerant CO2 (R 744). ArChine Cotoo POE 85 has an excellent solubility/miscibility with CO2 which guarantees the oil circulation in the refrigeration systems, especially at low evaporation temperatures.
