Cooling circulator

ZLJ series cooling cycle refrigerating machine is a multi-purpose cooling device, which can be used to conduct cold bath test on flasks and test tubes in the liquid storage cooling well.The equipment adopts compressor refrigeration, temperature control adopts PID control technology, temperature display adopts high brightness LED display, set cycle function, refrigeration function as one.The selection of refrigerant refrigerant carrier according to the required temperature in the refrigerating system, which is filled with refrigerant carrier according to the national standard and the relevant international conventions, is requiredNon – toxic, non – corrosive, non – sticky at low temperature.1. Distilled water or deionized water is recommended as the cooling medium when the temperature is above 10℃.2. Ethylene glycol solution is recommended when the operating temperature is -20 ~ 10℃.
