Eni Betula ESX 100
Ester-based synthetic oil for refrigeration compressors on HFC refrigerants
ISO VG 100
Eni Betula S 100 is a synthetic lubricant for refrigerating compressors, particularly recommended for hermetic type compressors (domestic fridges), open-type or partially sealed industrial units and heat pump systems that operate with standard refrigerating fluids (R-12, R-22, ammonia).
Refrigeration compressor oil KC — DIN 51503
Class KC of DIN 51503: an oil for refrigeration compressors running halogenated refrigerants, with which it is miscible.
Refrigeration compressor oil KAA — DIN 51503
Class KAA of the German standard for refrigeration compressor oils: a mineral oil for ammonia plants, not miscible with the refrigerant.
Lubricant classification DRA — ISO 6743
Class DRA: mineral oils for refrigeration compressors running ammonia or non-miscible refrigerants.
Lubricant classification DRC — ISO 6743
Class DRC of ISO 6743-3, for refrigeration compressors with low-temperature demands beyond a plain mineral oil.
Lubricant classification DRE — ISO 6743
Class DRE of ISO 6743-3, for refrigeration compressors running halogenated refrigerants, where the oil must return from the evaporator.
