About B320SH Refrigeration Oil

The B320SH is a high-quality complex synthetic ester (POE) compressor oil specifically made by BITZER for their compact screw compressors (CSH/CSW series) running on the R22 refrigerant, featuring an ISO VG 320 grade, excellent miscibility with R22, low water content, high flash point (around 258C), and a low pour point (around -42C), ensuring good lubrication, sealing, and oil return in air conditioning and refrigeration systems.

Key Specifications & Properties:

Type: Complex Synthetic Ester (POE)
Brand: Bitzer (OEM approved for R22 screw compressors)
Application: Bitzer CSH & CSW series screw compressors, R22 refrigerant systems (central AC, heat pumps, low-temp units)
ISO Viscosity Grade: 320 (ISO VG 320)
Viscosity (cSt @ 100C): 32 mm/s (or cSt)
Viscosity (cSt @ 40C): 298 mm/s (or cSt)
Flash Point (ASTM D 93): 258C - 271C (High)
Pour Point (ASTM D 97): -42C (Low)
Density: 1050 kg/m
Key Features: Excellent miscibility with R22, low water content, low Total Acid Number (TAN).

Why It's Used:
Ester oils like B320SH are essential for chlorine-free refrigerants (like R22) because they mix well, ensuring oil circulates back to the compressor, preventing damage.
