     Introduction

    The series of high and low temperature circulating devices are mainly used in the testing and production of pharmaceutical, chemical, biological products and other industries. They are mainly used to connect the interlayers of various reaction kettles. The high and low temperature silicone oil is pumped into the reactor interlayer through a circulating pump. The material reacts at high or low temperatures.

     

    Working Principle

    The circulating temperature pump is turned on by setting the required temperature through the meter. When the set temperature is lower than room temperature, the fully enclosed compressor is started, the refrigerant is used to enter the heat exchanger, the high and low temperature silicone oil is cooled, and the cooling oil is sent to the circulating pump. The reactor interlayer is used to indirectly cool the material in the kettle. When the cooling reaction is completed, it needs to be restored to the normal temperature or high temperature reaction, and the required temperature is reset. The circulation pump is always working, the compressor stops working, and the heating tube is in the heating cylinder. The heating work is carried out, and the cooling oil is slowly heated from a low temperature to a normal temperature or a high temperature, and the temperature of the material in the kettle is also brought to a desired temperature. The heating and cooling of the device can be quickly converted. The medium used (high and low temperature silicone oil) is the same medium. After connecting, there is no need to change the medium, which improves the disadvantages of the two instruments required for heating and cooling.

         The entire liquid circulation of the high and low temperature circulation device is closed, with an expansion container, the expansion container and the liquid circulation are insulated, do not participate in the liquid circulation, but are mechanically connected, regardless of whether the temperature of the liquid circulation is high or low, the expansion container The medium in the medium is below 60 degrees. It can achieve no absorption of water vapor at low temperatures, and no oil mist at high temperatures.

        This product is divided into size, temperature and temperature. Generally, the temperature is -20~+200°C, -40~+200°C. Various high temperature and low temperature ranges can be customized according to customer needs.
