Recirculating Heater & Chiller -45 to 250 °C

The recirculating heater & chiller can achieve dynamic temperature control from -45℃ to 250℃, and has heating and cooling functions. Equipped with two LED display controllers, which can display the set temperature value, actual value and over-temperature alarm value at the same time. This product has high efficiency, fast speed and simple liquid injection. The entire liquid circulation is a closed system without oil mist and water absorption, ensuring the safety of the experiment and the service life of the heat transfer medium. The performance of the compressor and circulating pump is stable and the quality is reliable; the product has safety protection functions such as self-diagnosis function, refrigerator overload protection, high-pressure pressure switch, overload relay, and thermal protection device.

Recirculating heater & chiller refers to a circulating device that provides heat and cold sources for reactors, storage tanks, etc., as well as laboratory equipment with dual functions of heating and cooling. It guides the thermal medium to circulate in a closed circulation system to heat or cool the required objects, that is, to establish a second constant temperature place. It is mainly used in glass reactors, rotary evaporators, fermentation tanks and measuring tanks in the fields of chemical industry, medicine and biology. Thermal instrument supporting; widely used in petroleum, metallurgy, medicine, biochemistry, physical properties, testing and chemical synthesis and other research departments, colleges and universities, factory laboratories and measurement and quality inspection departments.

1. Adopting a closed circulation system, the heat transfer oil is not easy to volatilize and oxidize at high temperatures, and has no oil mist; it is not easily affected by environmental conditions at low temperatures, which can extend the service life of the heat transfer oil.=

2. Heating/cooling: refrigeration can be started directly from high temperature to low temperature. Continuous operation and temperature control can speed up the experimental progress, save resources and improve work efficiency.

3. The refrigeration heat exchanger adopts a fully brazed plate heat exchanger, which takes up little space and has high heat exchange efficiency.

4. The circulation pump is a high-temperature-resistant oil pump with the characteristics of high-temperature resistance, low noise, and large flow rate.

5. It has over-temperature protection, leakage protection, over-current protection and other protection functions to fully ensure the safety of users and equipment.

6. The heating and refrigeration circulator has beautiful appearance, small size and reasonable structure.

7. According to the needs of users, air cooling and water cooling can be provided.
