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, the external circulating pipeline transports the refrigerant or the heat medium to the interlayer of the supporting equipment, and indirectly cools and heats the materials in the reactor.
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.
The heating and cooling of the explosion-proof high and low temperature circulator can be quickly switched. The medium used (high and low temperature silicone oil) is the same medium, and there is no need to change the medium after connection.
The entire liquid cycle of the high and low temperature cycle device is airtight, with an expansion vessel. The expansion vessel and the liquid cycle are insulated, and do not participate in the liquid cycle, but are only mechanically connected. No matter whether the temperature of the liquid cycle is high or low, the expansion vessel The medium in the medium is below 60°C. It can be achieved that there is no absorption of water vapor at low temperatures, and no oil mist is produced at high temperatures.
