Principle
The high and low temperature circulating machine precisely controls the liquid temperature in the tank through the built-in integrated PID automatic temperature control program combined with the High Accuracy PT100 temperature sensor. The heat-free centrifugal circulation pump and the porous U-shaped return circulation system are used to realize the turbulence and high uniformity of the flow field and temperature field in the tank, ensuring the temperature Stability. The refrigeration system adopts a fully enclosed and environmentally friendly Compressor, which can directly start the refrigeration in the high temperature state.
Applications
Petroleum, chemical industry, electronic instrumentation, physics, chemical and biological engineering, life sciences, light industrial food, physical property testing, chemical analysis
