Applications
KUNLUN L-DRE Refrigerator Oil isNaphthenic oil type refrigerator oil. It is suitable for all kinds of household refrigeration, civil commercial air conditioning, heat pump equipment, especially open and semi-closed refrigeration units with evaporation temperature above-30 °C, using hydro-chlorofluorocarbons ( HCFCS ) as refrigerant. It is also suitable for the oil demand of refrigeration compressor unit with isobutene ( R600a ) as refrigerant.
Note : The L-DRB / A and L-DRB / B products of the original GB / T 16630-1996 standard are merged, which corresponds to the L-DRE in the new national standard GB / T 16630-2012. The application site is limited to R22 ( difluoro-chloromethane ) refrigerant. The newly added technical indicators such as the chemical stability of the refrigerant, the compatibility with the refrigerant, and the pressure performance test pay more attention to the performance of the product.
Application cases
Kunlun L-DRE product is a very popular industrial refrigeration oil containing hydro-chlorofluorocarbons ( HCFCS ), which has a high application share in various industries. It is applied in the rotary compressor equipment of Panasonic, Meizhi, Haili, LG, Samsung, Ruizhi, Qing 'an and other household air-conditioning refrigeration equipment enterprises. Dalian Chiller Group and Zhuhai Gree Group specify the installed oil.
