-Danfoss, a global group of companies founded in Denmark in 1933 and headquartered in Nordborg, Denmark, is the largest industrial enterprise in Denmark.
-It is a world leader in the refrigeration, heating, water treatment and drive control manufacturing industries.
-The company is renowned for its use of advanced manufacturing technology and its concern for the environment.
Characteristics
1. Strong adaptability
- Designed for different refrigerants (e.g. R22, R404A, R407C, R134a, etc.) and compressor models (e.g. MT, LT, MTZ, etc.) to ensure compatibility with refrigeration systems.
- Some models are formulated with POE (polyester oil) or PAG (polyglycol oil), suitable for environmentally friendly refrigerants (e.g. R134a, R410A).
2. Excellent thermal stability and lubrication properties
- High flash point (177℃ for 160P, 258℃ for 160SZ) to ensure safety in high temperature environment.
- Low pour point (e.g. -51℃ for 160PZ) to ensure fluidity in low temperature environment.
3. Long life and low maintenance
- Low acid value (total acid value <0.05 mg KOH/g) to reduce corrosion on the system.
- High dielectric strength (e.g. 160SZ is 88 kV), enhancing insulation performance.
Application Scenarios
1. Industrial refrigeration system
- MT/LT compressor for cold storage, cold chain logistics, suitable for R22 and other traditional refrigerants.
2. Environmental refrigeration equipment
- If R407C is used in central air-conditioning or heat pump systems, ester oils such as 160SZ or 320SZ are required.
3. Laboratory and medical equipment
- Suitable for Danfoss compressor in ultra-low temperature experimental chamber (-60℃) to ensure low temperature lubrication performance.
