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, reduce the demand of 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 absorb the moisture and volatile.

With the progress of the society, the industrial development is also in a fast speed. Thus the refrigeration circulator has bee paid a lot of enterprises' attention.

Now a lot of chemical plants and laboratory research institutes, schools have a big demand for this, which can heat and cool at the same time. Its maximum temperature range can be achieved: - 25 ~ 200 degrees to make sure it can cool instantly under the condition of high temperature, which can realize continuous temperature control 200 to 25 degrees.

Compared with other enterprises, our refrigeration circulator's working temperature has a wide range, because our refrigeration equipment is a closed system. When at a low temperature it will not absorb moisture. While at a high temperature it will not produce oil mist. Heat conduction oil can adapt a very wide range of working temperature. Solenoid valves are not used throughout the circulation system. The circulation management is completely sealed without oil mist and water absorption, which guarantees the safety of the experiment and the life of the thermal conductivity. It also has a variety of security features.
