Synthetic ammonia refrigeration compressor fluid

Description
Coolmax PAO series are PAO based synthetic compressor fluids. They are specially formulated to lubricate compressors used in ammonia refrigeration systems. The problems normally seen (high oil consumptionreduced efficiency due to pipe clogging) will be history when Coolmax PAO series is used. Coolmax PAO series are fully miscible with conventional mineral oils, therefore a change-over procedure is fairly easy. High concentrations of mineral based product will however reduce the performance. Coolmax PAO series in its
compatibility with paints, seals, gaskets and hoses, is similar to mineral oils. No special precautions related to compatibility are required when changing over from a mineral oil lubricant.

Applications
Reciprocating and rotary screw compressors used in ammonia systems as well as gas compressors and vacuum pumps in process systems where ammonia vapours occur.
