Refrigerating compressors using NH3/ammonia.
High resistance to oxidation in the presence of ammonia. Base oils and additivation system specillay selected to avoid the formation of black sludges (reaction between oil and ammonia). Low pour point, eliminating the risk of any residual lubricant freezing in the evaporator, there by providing excellent heat exchange. Very high flash point given the low volatility of LUNARIA NH oils: oil consumption is reduced by 30 to 50 % compared with conventional oils. Good compatibility with common elastomers (chloroprene, NBR….). Warning: storage must be done in order to avoid the presence of water within the oil. Indeed, water could block the evaporator.
