Refrigeration lublicant oil(Emkarate RL66H)

Emkarate RL (manufactured by CPI Fluid Engineering, a division of The Lubrizol Corporation) is the industry-standard line of polyol ester synthetic lubricants designed specifically for refrigeration and air conditioning compressors. It is one of the most widely used and OEM-approved lubricant brands in the HVAC/R world, formulated to pair perfectly with hydrofluorocarbon (HFC), hydrofluoroolefin (HFO), and HFO-blend refrigerants. Key and Features Types: Broadly used across all major compressor technologies, including scroll, rotary, reciprocating, screw, and centrifugal compressors.Refrigerant Match: Engineered for optimal miscibility with eco-friendly refrigerants like R-134a, R-404A, R-410A, R-407C, and R-507, ensuring smooth oil return to the compressor.OEM Approvals: Extensively approved for factory-fill and field service by top global manufacturers like Copeland (Emerson), Bitzer, Carrier, Trane, and York. Why use unique cooling lublicant refrigeration oil. Excellent Wear Protection: Delivers a robust fluid film that reduces friction, protects critical internal bearings, and extends compressor life.Thermal & Chemical Stability: Resists breakdown under extreme operating temperatures and high pressures, preventing the formation of harmful sludge or varnish.System Efficiency: Maintains excellent fluid mobility at low temperatures, preventing oil logging in the evaporator and maximizing heat transfer efficiency. Common Viscosity GradesThe Emkarate RL line spans several viscosity grades to match specific system requirements. Some of the most common include:Emkarate RL 32H: A popular ISO VG 32 oil widely used in residential and commercial air conditioning and low-temperature refrigeration systems.Emkarate RL 68H: An ISO VG 68 oil frequently specified for medium to large commercial air conditioning systems and industrial screw compressors.Emkarate RL 170H / 220H: Higher viscosity oils designed for heavy-duty industrial applications requiring maximum load-bearing protection.
