Piston type refrigeration compressors working with Ammonia as refrugerant

 

The specificity of a lubricant for refrigerating a compressor is that it permanently contains a small quantity of refrigerant. The lubrication must thus be good in the presence of this small quantity of refrigerant. In the case of ammonia, there is a total immiscibility between the lubricant and the refrigerant; it is thus enough for the lubricant to have a pour point lower than the temperature of the evaporator to make sure of its proper return to the compressor.

Molylub RCF series are high quality, hydrotreated naphthenic mineral oils without additives. Specific selection of the base oil gives a range of products specially suited for the efficient lubrication of refrigerator compressors.

Molylub RCF series are designed for the lubrication of compressors with ammonia (R717) as refrigerant. It can also be used when hydrocarbon (e.g. R600a) are the refrigerant. It may be used with halogenated hydrocarbon (R12, R22)
