Danfoss 320SZ

Danfoss 320SZ is a high-performance synthetic refrigeration compressor oil engineered to deliver exceptional lubrication, cooling efficiency, and long-term protection in Danfoss scroll and reciprocating compressors. Designed for use with modern HFC refrigerants such as R-410A, R-407C, and R-134a, 320SZ offers superior chemical and thermal stability, ensuring reliable operation even under high-pressure and high-temperature conditions. Its advanced POE (polyol ester) formulation provides excellent miscibility with refrigerants, ensuring efficient oil return and optimal heat transfer throughout the system. Danfoss 320SZ also resists moisture absorption, oxidation, and acid formation, helping prevent corrosion, sludge buildup, and compressor damage. Ideal for commercial HVAC systems, industrial cooling applications, and high-efficiency heat pumps, this lubricant ensures smooth operation and extended compressor life. Trusted for its OEM-grade performance, Danfoss 320SZ supports energy-efficient, stable, and trouble-free refrigeration system operation.
