| Product Overview
SynCold® GS series refrigeration lubricants are specially formulated synthetic naphthenic lubricants designed for compressors in commercial and residential refrigeration and air-conditioning systems. The SynCold® GS series boasts exceptional chemical stability, extremely low wax content, and outstanding low-temperature performance, ensuring long‑term equipment reliability. These lubricants are compatible with a wide range of refrigeration compressor applications and exhibit suitable miscibility with HCFC and CFC refrigerants as well as natural refrigerants.SynCold®GS is ideally suited for low-cost applications, particularly air-conditioning systems with evaporator temperatures no lower than –18°C, including residential, commercial, and industrial refrigeration and air-conditioning systems. In addition to being compatible with HCFC and CFC refrigerants such as R22 and R12, it also delivers excellent performance when used with natural refrigerants, including R717, R600a, and R290.

| Technical Features and Performance Advantages
Features Advantage Excellent low-temperature performance It meets the compressor’s requirement for seamless transition between high‑temperature and low‑temperature operating zones, preventing the refrigeration lubricant–refrigerant mixture from forming waxy, flocculent precipitates in the system’s low‑temperature sections. Good oxidation stability and thermal stability It prevents excessive carbon deposits from accumulating on high-temperature components such as the discharge valve, ensuring a long service life for the refrigeration lubricant. Excellent lubricity Provides effective oil-film protection, delivering excellent lubrication and heat dissipation. Good miscibility with refrigerants Even when diluted by the refrigerant, it still maintains a high‑strength oil film under high‑temperature operating conditions, while ensuring optimal oil return performance in the refrigeration system. Good insulation properties Meets the motor insulation requirements for fully enclosed and semi‑enclosed refrigeration compressors. | Technical Specifications
