Sanjing Chemglass


LR Standard & Explosion Proof Type Heating And Cooling Circulator

Short Description:

This machine is applicable to jacketed glass reactor for low temperature and cooling reaction. The whole cycling course is sealed, expansion tank and liquid cycling is adiabatic, they are only mechanism connection. No matter the temperature is high or low, the machine can be converted directly to refrigeration and cooling mode if it is under the high temperature condition.
