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.

The Correct Use of the Refrigerant in the Temperature Control System

If the temperature control system has been used for more than six months, or the high and low pressure often fails, or the cooling capacity is reduced, please arrange the staff to clean the radiator.We all know that refrigerants are an essential material for the use of temperature control systems. Then do you know how much the refrigerant is suitable for the temperature control system in subzero 90 to 250?

When the temperature control system uses the pump filling machine to fill the refrigerant, it only needs to close the empty cut-off valve on the empty filling machine after the end of the pump, and the refrigerant can be filled to the refrigeration system by opening the filling valve. Under the certain amount of the filling in the cold water machine, neither too much nor too little, the small temperature control system use the quantitative filling device to fill the refrigerant by filling the refrigerant, it only needs to close the three valves after the vacuum of the refrigerating device and stop the vacuum pump, and dismantle the joint of the pressure resistant rubber tube connected with the vacuum pump and install it in the quantitative filling device. Open the liquid outlet valve and drain the air in the hose, then tighten the connector of the hose to check whether it leaks.

When the refrigerant of the temperature control system is filled with the refrigerant, read the pressure gauge on the filling device at the very first, the rotate the scale sleeve, and the quantitative liquid line corresponding to the pressure gauge is found on the sleeve, and the initial level of the liquid surface of the refrigerant in the glass tube is recorded. Then open the three-way valve, the refrigerant enters the refrigeration system through the hose, and the liquid level of the refrigerant in the glass tube begins to decrease. When the required amount of filling is achieved, close the discharge chamber and the three links on the charging device and the charging operation end.

The temperature control system is used in many fields. Plastic, electronic. Electroplate。 Laser, food, textile, chemical industry. Packing。 Medical care。 Even in industries such as test and even beverage, the industrial refrigeration equipment and temperature control system group play a very important role in beer production line.
