PRODUCT DESCRIPTION
ArChine Cotoo NTG 68 is unique custom blend of synthetic Polyolester(POE) with additives for excellent wear protection, oxidation stability and lubricity.ArChine Cotoo NTG 68 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 NTG 68 is developed for use mainly in refrigeration systems which are working with the refrigerant CO2 (R 744). ArChine Cotoo NTG 68 has an excellent solubility/miscibility with CO2 which guarantees the oil circulation in the refrigeration systems, especially at low evaporation temperatures.
