Explosion proof high and low temperature circulator

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 by a fully enclosed compressor, composed of plate heat exchangers, expansion valves, and pressure protectors to meet the cooling requirements; the heating part is the use of electric heating tubes to heat the circulating fluid. And through the built-in circulating pump and the external circulating pipeline, the refrigerant or heat medium is transported to the interlayer of the supporting equipment, which indirectly cools and heats the materials in the reactor.

Set the required temperature through the panel. When doing a low temperature reaction, the high and low temperature silicone oil is cooled, and the cooling oil is transported to the interlayer of the reactor through a circulating pump to cool the materials in the kettle. When the cooling reaction is over, it needs to return to normal temperature or During the high temperature reaction, the required temperature is reset, the circulating pump and heating pipe work to slowly heat the cooling oil from low temperature to high temperature, and the temperature of the materials in the kettle will then reach the required temperature.

The heating and cooling of the equipment can be quickly changed. The same high and low temperature silicone oil is used as the medium. The silicone oil does not need to be replaced when the machine is used, which improves the disadvantage of requiring two different instruments for heating and cooling.

During external circulation, connect the upper outlet pipeline of the product to the lower inlet pipeline of the kettle body, and the circulating fluid will return from the upper circulation port through the pipeline to the lower return port of the product to form a complete circulation space.
