Temperature Control Cooling Heating Circulator Units

Temperature control cooling heating circulator refers to a circulation device that provides heat and cold sources for reactors, tanks, etc., and is a laboratory instrument and equipment with dual functions of heating and cooling. It can be used with experimental instruments (glass reaction kettle, rotary evaporator, fermentation tank, calorimeter), and can automatically heat or cool according to set requirements. It has precise temperature control, universal heating and cooling functions, and can meet the needs of various biochemical experiments. need.

Characteristics of temperature control cooling heating circulator

Wide temperature control range: -120℃ ~ 250℃

Pre-cooling system, refrigeration system and heating system can be used together

Rapid heating or cooling, fast cooling rate, forced rapid cooling

Fully closed circulation system, the heat transfer fluid is not easy to volatilize and oxidize at high temperatures, and is not easily affected by environmental conditions at low temperatures, which can extend the service life of the heat transfer fluid

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

Liquid level display function, real-time monitoring of liquid level to avoid lack of heat-carrying fluid

Over-temperature protection, leakage protection, over-current protection and other protection functions fully ensure the safety of users and equipment

According to customer needs, models with two pre-cooling methods, air-cooling and water-cooling, are available.

Advantages of temperature control cooling heating circulator

1. Multiple control methods: with fixed value and segmented program control.

2. Fast heat transfer: large flow circulation pump and large hose section ensure flow rate and heat transfer

3. Space saving: compact structure, taking up less space

4. Safety guarantee: over-temperature protection, leakage protection, over-current protection and other protection measures

5. Pre-cooling function: Unique pre-cooling function, fast room cleaning and low power consumption, saving energy

6. Appointment function: Set the device opening time and operating conditions to achieve automatic opening and safe operation.

7. High process safety: In high-temperature areas, the pre-cooling system and circulation function are used to achieve safe cooling, meet the condition requirements of process tests, and extend the service life of the equipment.

8. Perfect exhaust function: The heat-carrying fluid circulation system is equipped with an exhaust port, which can smoothly complete the filling of heat-carrying fluid.

9. Color touch screen: can clearly display information related to the working process and material temperature change characteristic curves

10. High temperature control accuracy: using PID control method to optimize temperature control parameters, the control accuracy can reach ±0.5℃

11. Convenient data communication: equipped with data interface, USB interface and external sensor interface as standard.
