Drive compressor refrigeration: Drive the compressor to run, realize the refrigerant circulation, provide a continuous low temperature environment for ice making, and ensure the rapid condensation of ice cubes. Work together to ensure that all links of the ice machine are carried out in an orderly manner and realize automatic ice making. Adapt to the ambient temperature: automatically adjust the speed according to the ambient temperature, enhance the operating power in the high temperature environment, and ensure that the ice making efficiency is not affected. 1pc Small Waterproof Pump DCM3512-420 Circulation Micro Submersible Pump 50cm Cable Home Mini Commercial Ice Maker Parts, Manufacturer: GENTERUN
