Product Description

                   Touch screen Gdsz-20/40 Heating and Cooling Circulating Device




Working principle:

 This product has both cooling function and heating function. It is composed of refrigeration unit, heating unit, circulation system and control system.
The refrigeration part is mechanically refrigerated with a fully enclosed compressor, matching with air-cooled condenser, plate-type heat exchanger, expansion valve, pressure protector, etc. to meet the cooling requirements. The heating part is to use an electric heating tube to heat the circulating fluid. The refrigerant or the heating medium is transported to the interlayer of the supporting equipment through the built-in circulation pump and the external circulation pipeline, indirectly cooling and heating the materials in the reactor.
During external circulation, the upper outlet pipeline of this product is connected to the lower inlet pipeline of the kettle body, and the circulating fluid is returned from the upper circulation port through the pipeline to the lower return port of the product to form a complete circulation.
