Coolmax SAB 68
Synthetic ammonia refrigeration compressor fluid
Description
Coolmax SAB 68 is a synthetic, developed to lubricate ammonia refrigeration compressors, both alternative and rotary. It is an oil with very low evaporation tendency.
Coolmax SAB 68 is formulated with synthetic and alkyl benzene bases of great chemical stability, which allows improving the behavior of cooling oils based on both naphthenic and paraffinic mineral oil. The result is a fluid with a longer lifespan and a significant reduction in operating costs.
Applications
For the lubrication of ammonia refrigeration systems, cold stores, food processing plants, freezer vessels, etc. It is also recommended in plants where very precise control is required at low temperature, such as the pharmaceutical and microelectronics sector. It can be used in those ammonia refrigeration systems where evaporator temperatures are higher than -50oC.
Coolmax SAB 68 is compatible with all mineral oils (hydrotreated, paraffinic and naphthenic) so it can be used to refill systems that work with this type of oils. However, a complete oil change is necessary to obtain all the advantages offered by Coolmax SAB 68
It is also compatible with seals and elastomers commonly used in this type of compressors including NBR, Neoprene and Buna-N.
