INQUIRY

LOW TEMP. REFRIGERATION CIRCULATOR

Circulating refrigeration of ethylene glycol mixed with water mixture

After the medium enters the extraction tank, it must be closed,the sandwich is heated, and the refrigerant is turned on to reducethe heat source of the boiling tank, and the steam is cooled backto the tank to maintain circulation and temperature.
