BITZER B320SH

Bitzer B320SH is a premium synthetic polyolester (POE) refrigeration compressor oil specifically formulated for use with HFC refrigerants such as R-134a, R-404A, R-507, and R-407 series blends. Engineered to deliver superior lubrication under high-temperature and high-pressure conditions, B320SH offers excellent thermal stability, oxidation resistance, and low-temperature fluidity. Its strong miscibility with HFC refrigerants ensures efficient oil return and consistent compressor performance across a wide operating range. Bitzer B320SH minimizes wear, reduces friction, and prevents the formation of harmful deposits, extending compressor life and improving system reliability. The oil’s advanced formulation also enhances energy efficiency by maintaining proper viscosity even under demanding loads. As an OEM-approved lubricant, B320SH is widely used in commercial refrigeration, industrial cooling, and air-conditioning systems requiring high-performance POE oils. This makes it a trusted choice for maintaining optimal performance in modern HFC-based Bitzer compressors.
