Introduce
High and low temperature integrated machine is also called high and low temperature circulator, heating and cooling circulation integrated machine, high and low temperature circulation integrated machine, simply put, it is a device that integrates the two functions of heating and cooling in one system, and specially provides a constant cold source and heat source for the reactor jacket. It drives the heat transfer medium (usually thermal oil or pure water) by pump from the tank with the built-in heater to the temperature-controlled jacketed reactor, and from the temperature-controlled jacketed equipment back to the heater tank. The high and low temperature control system adjusts the power of the heater or compressor and accurately adjusts the temperature of the hot fluid according to the temperature sensor PT100 measured by the temperature sensor PT100 or the internal temperature of the temperature control equipment, so as to achieve the temperature required by the temperature control equipment with an accuracy of ±0.5℃.
Advantages: High and low temperature all-in-one machine, adopting fully enclosed pipeline design, using plate heat exchanger, reducing the demand for heat transfer liquid, improving the heat utilization rate of the system, and achieving rapid rise and fall temperature. The thermal conductive medium is in a closed system, with an expansion vessel, the thermal conductive medium in the expansion vessel does not participate in the circulation, whether it is high temperature or low temperature, the expansion tank temperature is normal temperature to 60 degrees, which can reduce the risk of the thermal conductive medium absorbing moisture and volatilization during operation.
Typical applications of refrigeration, heating and temperature control systems
Dynamic constant temperature control of high-pressure reactor cold and heat source, dynamic constant temperature control of cold and heat source of double-layer glass reactor, constant temperature control of cold and heat source of microchannel reactor, small constant temperature control system, temperature control of steaming and saturation system, low-temperature and high-temperature aging test of materials, constant temperature control of combined chemical cold source heat source, cooling and heating of semiconductor equipment, constant temperature control of vacuum chamber refrigeration and heating.
