Production Workshop Real Map


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.

Glycol Chiller System SUNDI -10℃ ~ 200℃, as we can tell from its name, it is to use Glycol as the refrigeration agent for the chiller.

In the all air environment, because of the low temperature in the outdoors, it is impossible to use a cooling tower to supply the inner area directly with the cold air-conditioner. In addition, the cold air in the outdoors could be used directly as refrigerator source,with glycol as refrigerant, it can introduce the natural cold air into the inner area and supply cold air-conditioner. If we need to heat the outer area and provide cooling for the inner area, we can turn off the chiller and still use the boiler or the urban hot water as the heat source to heat the outer area.

Refrigeration principle of glycol chiller system

Install plate heat exchanger in the outdoor, and the outdoor cold air is introduced into the plate heat exchanger by the fan. The glycol solution and the outdoor cold air are exchanged in the plate heat exchanger. The cooled glycol solution enters into the air conditioners in the inner area and exchange with mixed air. Then the mixed air enters into the inner room with lower temperature and supply cooling. The temperature of glycol solution rise up, it comes back to the plant heat exchanger in the outdoor again, exchange heat with the cold air in the outdoor and continue this cycling after the temperature is lowered.  This way of heat exchange is usually used in the heat recycling system.

It is a very energy-saving way that use glycol as a refrigerant to introduce the cold air in the outdoors to supply cooling for the inner area. All we need to do is to install a plant heat exchanger in the outdoor when it works, the cold water equipment closed, opening the fan and the air conditioners can bring cooling for the inner area. In this way, we can save energy and reduce the cost.
