About 320SZ Refrigeration Oil
Danfoss 320SZ is a Polyolester (POE) synthetic refrigeration oil, specifically a ISO VG 320 grade, designed for use with HFC/HFO refrigerants (like R134a, R404A, R407C) and older R22 systems, offering excellent lubricity, thermal stability, and miscibility to ensure proper compressor function in air conditioning, refrigeration, and heat pumps. Key specs include a viscosity of around 320 cSt @ 40C and good low-temperature properties.
Key Specifications & Characteristics:
- Type: Synthetic Polyolester (POE).
- Grade (Viscosity): ISO VG 320 (approximately 320 cSt at 40C).
- Applications: Lubricating compressors for A/C, refrigeration, heat pumps.
- Refrigerant Compatibility: Works with HFCs (R134a, R404A, R407C/F, R507A) and HFOs (R1234yf, R450A, R513A) and older R22 systems.
- Performance: Offers good miscibility with refrigerants at low temperatures, excellent lubricity, and corrosion protection for longer compressor life.
- Viscosity @ 40C: 320 cSt (typical range might be 288-352 cSt).
- Viscosity @ 100C: Around 8.9 cSt.
- Flash Point: Approx. 240-263C.
- Pour Point (Low Temp): Around -43C to -54C.
- Dielectric Strength: High (e.g., 49.4 kV).
In essence, 320SZ is a high-performance synthetic oil for demanding refrigeration/AC
