Electronic auto-control, and separate control for each tank. Body material are used AISI 304 stainless steel, high light, avoid rust. Tank material are used PC plastic, high/low temperature resistance, innoxious, antiflaming and good flexibility. Electromagnetic transmission shaft, magnetic transmission which is applied on refigeration system to control the refrigerant flow precisely, is much better than electro transmission shaft, long life time. Condenser with copper tube, fast cooling, avoid leak High capacity with low power Compressor brand is AC, fast cooling speed, stable, long lifetime .Evaporator, double refrigeration, frozen fast .Cooling method is air-cooling. Slush comes during 30min-45mi . slush machine is easy to move , simple to maintain and easy to operate.
