REFCOMP PRL Rvn no : 1

Synthetic Ammonia Refrigeration Compressor Fluid

Description
REFCOMP PRL 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 REFCOMP PRL series is used. This 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. This 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.

Advantages

Fully compatible with ammonia
Contains a minimum of additives
Prevent deposit formation in low temperature systems
Reduces discharge valve deposits
Excellent lubricity
High film strength
Zero wax content
Improves compressor efficiency
Low volatility
Very low vapour pressure

Gas type compatibiltiy

Refcom PRL is suitable for processing the following gases:

R717 (ammonia)	R290 (propane)	R22
