SUNISO GSD Series frozen oil (2GSD, 3GSD, 4GSD, 5GSD, etc.) is a series of high-quality refrigeration compressor lubricants, and general refrigerant completely coincide, their chemical properties are very stable, not containing waxy, long-term non- Failure to use. This series of lubricants used in various types of compressors, has a long and successful history, most compressor manufacturers specify the use of this oil, such as Hitachi, Daikin, Sanyo, Copeland, Han Zhong, Fu Sheng, Qing Yu, Panasonic, Toshiba, McQuay refrigeration compressor manufacturers, the oil while the new machine and repaired the old machine to the factory. Purpose (Application) This series of lubricants for refrigeration compressors Freon and alkanes environmentally friendly refrigerant compressors. An evaporator temperature is below -18 ℃ cryogenic systems, including residential and commercial refrigerators and air conditioning. Follow compressor manufacturer's instructions, the choice of the appropriate SUNISO GSD series lubricants. Characteristics (Characteristics) from selection of naphthenic crude oil refined by a special method, does not contain wax, the refrigerant can be mixed with each other without causing general response. Chemical stability, so the application period may be extended lubricant, reducing maintenance times and costs. Compressor to keep cleaner operations, reduce sediment generation, so as not to obstruct the refrigeration system.
