Explosion-proof high and low temperature integrated machines are used in the current pharmaceutical and chemical industry. The heat transfer medium of the entire circulation system is a fully closed cycle, the circulation system has a liquid expansion container, the expansion container and the liquid circulation are independent systems, and the expansion container does not participate in the liquid circulation, but is a mechanical connection. Even in the case of high temperature operation, the heat transfer medium in the expansion vessel will not be higher than 50 degrees.

The traditional explosion-proof high and low temperature integrated oil tank is large in volume. When the slotted system controls the external circulation, such as the jacket reaction, the larger the volume of the reactor is, the larger the volume of the jacket is. The more heat transfer medium of the whole system, the heating and cooling process The greater the change in concentration, the greater the volume requirement of the oil bath and water bath. The heat load during the temperature change of the whole system is the total heat transfer oil of the whole system (mainly). The reactants in the reactor body, the larger the volume of the water bath and the oil bath, the smaller the effective power for the kettle body, and the temperature of the reactants in the kettle body is raised. And the slower the speed response and rate of cooling. The temperature control of the explosion-proof high and low temperature integrated machine reactor is controlled by the temperature change of the heat transfer oil of the reactor jacket. The more heat transfer medium is in the system, the less the effective power is used in the kettle body, and the temperature rise and fall. The slower.

The whole cycle of the explosion-proof high and low temperature integrated machine is sealed, no oil mist is volatilized at high temperature, the heat transfer oil is not easily oxidized and browned; the low temperature is not easy to absorb the water vapor in the air; the service life of the heat transfer oil is prolonged. With self-diagnosis function, freezer overload protection, high-pressure pressure switch, overload relay, thermal protection, high-temperature heating, high-voltage protection device, and other safety protection functions, fully ensure the safety of use. The explosion-proof high and low temperature integrated machine adapts to the control system during the control process (such as the chemical reaction process), continuously adjusts the PID parameters to give the process control temperature and response time. This process is effective in multi-directional measurement of temperature and temperature. The rate of change and temperature change is achieved.

Moreover, the equipment of different manufacturers is different. The user needs to configure and select the model according to the specific manufacturer. After all, it is very important to choose high-performance explosion-proof high and low temperature integrated machine.
