SUNISO® GS lubricants are premium quality, highly-refined mineral refrigeration fluids designed to lubricate refrigeration and air-conditioning compressors using CFC and HCFC refrigerants. Suniso GS fluids are known for their low wax content, low pour point and high dielectric strength. For over 50 years, Suniso GS fluids have helped to ensure trouble-free operation and maximum service life with excellent chemical and thermal stability
Get in touch regarding the GS range:
- Low Wax Content & Low Pour Point: Excellent low-temperature performance with no wax deposits to plug the system.
- High Dielectric Strength/Good Electrical Insulating Properties: Suitable for hermetically sealed compressors (electric motor and windings exposed to refrigerant and oil).
- Excellent Chemical Stability: Does not react with refrigerant or metal components in the system, extending machine service life and reducing maintenance costs.
- High Thermal Stability: Cleaner operation of the compressor with minimal deposits and failures due to valve sticking.
- Recommended for use in consumer and commercial refrigeration and air-conditioning systems charged with traditional and natural refrigerants.
- Ideally suited for low-temperature systems where evaporator temperatures are as low as -42ºC / -44ºF.
- Designed for use with CFC refrigerants (e.g. R-11, R-12, R-13, R-113, R-114,
R-115) and HCFC refrigerants (e.g. R-21, R-22, R-123, R-124, R-141b, R-142b,
R-502). - Suitable for use with natural type refrigerants, including ammonia (R-717), isobutane (R-600a) and propane (R-290).
