Refrigerated Heating Circulator Unit

Refrigerated heating circulator unit refers to a circulation device that provides heat and cold sources for reactors and tanks, as well as laboratory equipment with dual functions of heating and cooling. It guides the thermal medium to circulate in the closed circulation system to heat or cool the required objects, that is, to establish a second constant temperature place. It is mainly used for supporting glass reactors, rotary evaporators, fermentation tanks and calorimeters in the chemical, pharmaceutical and biological fields. ;Widely used in research departments, colleges and universities, factory laboratories and metrology and quality inspection departments such as petroleum, metallurgy, medicine, biochemistry, physical properties, testing and chemical synthesis.

1. Wide operating temperature range, with heating and cooling functions. Temperature range: -45℃～250℃.

2. The controller with two LED displays can display the temperature set value, actual value and over-temperature alarm value at the same time.

3. Efficient, fast and simple liquid filling.

4. Ensure rapid cooling at high temperatures; can achieve continuous temperature control from 250°C to -45°C.

5. The circulation management is fully closed, no oil mist, no water absorption, ensuring the safety of the experiment and the service life of the heat transfer fluid.

6. The compressor and circulation pump of the refrigeration unit have stable performance and reliable quality.

7. The heating and refrigeration circulator has self-diagnosis function; refrigerator overload protection; high-pressure pressure switch, overload relay, thermal protection device and other safety protection functions.

8. Control the temperature of the heat transfer medium. The same heat transfer medium is used throughout the heating and cooling processes.

9. High-lift design meets the long-distance transportation of heat-conducting media.

Refrigerated heating circulator unit is a circulation device that can provide cold source and heat source. The entire liquid circuit is closed with an expansion vessel. The expansion vessel is insulated from the liquid circulation and does not participate in the liquid circulation, but is mechanically connected. Regardless of the temperature of the liquid circulation, the medium in the expansion vessel is lower than 60°C, and the entire liquid circulation is a closed system. It does not absorb water vapor at low temperatures and oil mist at high temperatures. Thermal oil can work in a wide temperature range; the entire circulation system does not use mechanical valves and electronic valves.
