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, 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.

How Does the Industrial Chiller Release Gas?

1. When air is released by air separator, the return value of the air separator should be placed in the normal open state to reduce the pressure of the air separator to the suction pressure, and the other valves should be closed.

2, Appropriately open mixed gas inlet valve to make the industrial cold water machine 40 ℃ ~ 200 ℃ below zero in mixed gases into the air separator.

3. Micro-open feed valve, so that the refrigerant is fed into the air separator to vaporize and absorb heat and cool the mixed gas.

4. The rubber hose used to connect the air vent valve interface enables one end to be inserted into the water container. When the refrigerant in the mixture is cooled into ammonia, the air separator is frosted at the bottom of the air separator, and the air valve can be opened slightly and the air is discharged through the water container. If the bubbles in the water rise in the process of the circular without the changing of volume, the water is clear and water temperature is not rising, then the air is released, at this time you should make the appropriate opening of the air valve.

5. The coolant in the mixture is gradually condensed into the coolant liquid and deposited at the bottom.The height of the liquid level can be seen from the frosting condition of the shell. When the liquid level reaches 12, close the supply throttle valve and open the return flow throttle valve. The underlying refrigerant liquid is returned to the air separator to cool the mixture. When the bottom layer is about to melt, turn off the return throttle valve to open the supply throttle valve.

6. When the air is stopped, the air valve should be closed first to prevent the coolant from leaking, and then the liquid throttle valve and the mixed gas inlet valve shall be closed. The return valve should not be closed to prevent increased pressure in the air release.
