Product Description
5GS Mineral Refrigeration Oil is a high-performance naphthenic lubricant designed for refrigeration and air conditioning systems using CFC, HCFC, and ammonia refrigerants. It provides excellent lubrication, strong film strength, and reliable protection for compressors operating under heavy-duty conditions.
This highly refined, wax-free mineral oil ensures a low pour point and smooth performance at low temperatures. Its superior dielectric strength makes it suitable for hermetic compressors, while its compatibility with refrigerants like R22 and ammonia ensures stable and efficient system operation.
5GS is ideal for high-load and industrial applications where higher viscosity is required, making it a trusted choice for demanding refrigeration environments.
