These specialized products are designed for use in ammonia refrigeration systems. They offer excellent lubrication for ammonia compressors due to their low temperature fluidity and very low solubility in ammonia. Users can benefit from reduced oil consumption of up to 80% compared to naphthenic oils thanks to their low volatility. In addition, the oil lifespan can be increased by up to a factor of 5, depending on the system temperature and equipment condition, when compared to naphthenic oils.
