-60℃～300℃

A fully closed piping design, high efficiency plate heat exchanger used to reduce the demand for the thermal fluid utilization while providing the system to achieve the rapid ups and downs in temperature The whole system is a closed liquid circulation system with the expansion of container, expansion of the container and the liquid circulation is adiabatic, and do not participate in liquid circulation, only mechanical connection, regardless of the temperature is a high temperature or low temperature, the tank temperature is limited to 60℃. Therefore, during the process the risk of imbibing and volatilization of the heat conducting medium is reduced. There following advantages for the user.

Typical application of refrigeration heating temperature control system

Dynamic thermostatic control of cold and heat source of high pressure reaction kettle, dynamic thermostatic control of double layer glass reaction kettle, and dynamic thermostatic control of cold and hot source of double-layer reactor.Microchannel reactor thermostatic control, small temperature control system, steam - feeding system temperature control, material low temperature aging test.The thermostatic control of the combined chemical cold source heat source, the cooling heating of the semiconductor equipment and the heating temperature of the vacuum chamber are controlled.

Advantages and functions of temperature control system of refrigeration

Temperature range from 120 to 350, performance superior, unique, high - precision, intelligent temperature control.High cooling power from 0.5 to 1200kW, highest production stability and repeatable results.Multi-function alarm system and safety function, use plate heat exchanger, tube type heater to increase heating and cooling rate.7-inch and 10-inch color TFT touch screen graphics display, use magnetic drive pump, no re-seal leakage problem.Full airtight system, extended thermal conductivity liquid life, very wide temperature range, no need to change liquid media.Ultra-high temperature cooling technology can be cooled directly from 300 degrees of high temperature.The principle and the function has many advantages to using staff: because only expansion of cavity in the body heat conduction medium contact with oxygen in the air (and expansion tank temperature at room temperature to 60 degrees), can achieve lower heat conduction medium absorbed by oxidation and the risk of air moisture.No heat conduction medium evaporates at high temperature, and it can be achieved -80 ~ 190 degrees, -70 ~ 220 degrees, -88 ~ 170 degrees, -55 ~ 250 degrees, -30 ~ 300 degree continuous temperature control without pressurization.

Adopt full closed pipe design, adopt high efficiency plate heat exchanger, reducing the demand for heat conduction liquid, improve the heat utilization rate of the system, reach the rapid lifting temperature.Thermal conductive medium in a closed system, with a container, expand the heat-conducting medium not participate in circulation in the container, whether high or low temperatures, expansion tank temperature to room temperature to 60 degrees, can reduce the heat conduction medium in running the risk of absorbing the moisture and volatile.
