Application
The selected naphthenic crude oil is refined by special treatment methods and has excellent lubricity, chemical stability, low temperature characteristics and good solubility with refrigerant. It is suitable for HCFC refrigerant (R-22, R-502), natural refrigerant (R-600a, R-717, R-290) and CFC refrigerant (R-12). Can be used in reciprocating, rotary, scroll, and turbine compressor and other types.
Application Cases
The product has excellent lubricity, chemical stability, low temperature characteristics and good solubility with refrigerant. Therefore, it can maintain the long-term stability of refrigeration system performance in use. It is used in compressor equipment of Panasonic, Michi, Haili, LG, Samsung, Ruizhi, Qingan, and it is the designated loading for SANYO of Dalian and Shengyang (The original name L-DRC/B56 Refrigerated oil).
Performance Characteristics
|
Technical Characteristic |
Effect |
|
Excellently low temperature performance |
Meeting the requirements of freely convert from High-Temperature to Low-Temperature working area，Prevents oil/refrigerant mixtures from forming flocculent wax deposits at low temperatures in the system. |
|
Favourable oxidation and thermal stability |
Does not accumulate excessive carbon deposits at high temperatures such as the discharge valve, ensured the long using life of oil |
|
Excellent lubricity |
Providing effectively oil-film protection and good lubrication and heat dissipation |
|
Favourable Miscibility |
Although diluted by refrigerant, it can still have high strength oil film under extremely high temperature operating conditions，Guaranteeing the performance of oil recovery in the refrigeration system |
|
Favourable t insulating |
Meeting the motor insulation requirements of fully closed and semi-closed refrigeration compressors |
|
Environmental authentication |
acquiring authority inspection institutions(SGS) certification |
