Typical Application Of Dynamic 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. Micro-channel 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.


Structure and principle of Dynamic Temperature Control System: 

Ultra high temperature cooling technology can directly cool from a high temperature of 300℃(because only the heat transfer medium in the expansion chamber contacts with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60℃), which can reduce the risk of heat transfer medium being oxidized and absorbing water in the air. At high temperature, no heat conducting medium evaporates, and continuous temperature control of – 80℃ ~ 190℃, – 70℃ ~ 220℃, – 88℃ ~ 170℃, – 55℃ ~ 250℃ and – 30℃ ~ 300℃ can be realized without pressurization.

Advantages of Equipment Functions and Accessories

When the temperature is high, there is no evaporation of heat conducting medium, and the continuous temperature control of -90~195℃,-70~220℃,-55~250℃ and -25~300℃ can be realized without pressure. Adopt the design of fully closed pipeline, reduce the demand of heat-transfer fluid, improve the heat utilization rate of the system, and achieve rapid temperature rise and fall. The heat conducting medium in the expansion vessel does not participate in the circulation, which can reduce the risk of moisture absorption and volatilization during the operation of the heat conducting medium.
