Where the refrigerant is essential for the cooling properties of a refrigeration system, the refrigeration oil is crucial for the correct functioning of the compressor. It mainly plays four roles: lubrication, sealing, cooling, and energy regulation.
The WPCOOL "Robust series" oil charging pump is developed for wide types of refrigeration compressors, represented by the electric oil charging pump series, which solves the charging problem of large flow under large back pressure, saves labor and improves efficiency. At the same time, Considering the high viscosity of refrigeration oil in winter, We first developed an unlimited electric charging series for all kinds of refrigeration oil Worldwide.
