Heating and Cooling Circulating Thermostat Device

The heating and cooling constant temperature circulation device is a temperature control device that integrates heating and cooling functions. It can keep the equipment, materials or experimental media within a constant temperature range.

Composition of the heating and cooling constant temperature circulation device

1. Refrigeration unit: A closed loop is formed through the compressor, condenser, expansion valve (throttle valve) and evaporator, and the heat is taken away by the principle of heat absorption by the phase change of the refrigerant to achieve cooling.

2. Heating unit: Usually an electric heater or other heating element is used to add heat to the circulating medium as needed to achieve the purpose of heating.

3. Temperature control system: Contains high-precision temperature sensors and intelligent controllers to monitor and adjust the temperature of the circulating liquid in real time to ensure that the temperature is stable at the set value.

4. Circulation pump and pipeline: Ensure that the medium continues to flow in the system to achieve uniform temperature distribution, and overcome the circulation resistance through the pressure of the pump.

5. Safety protection system: Equipped with safety measures such as overload protection and high temperature protection to ensure safe and reliable operation of the equipment.

The advantage of this type of device is that it can provide a wide temperature control range, from cooling below ambient temperature to heating far above room temperature, and the temperature control accuracy is high, which is suitable for biopharmaceuticals, chemical synthesis, material testing, semiconductor processing and other fields.

Purchase considerations for heating and cooling constant temperature circulation devices

Temperature range: Determine the required minimum and maximum temperatures according to actual needs.

Accuracy and stability: Select equipment that can meet the temperature control accuracy requirements in experiments or production.

Cycle rate and capacity: Select a circulation pump with a suitable flow rate based on the amount of material processed or the system volume.

Energy efficiency ratio: Consider the operating cost of the equipment and give priority to products with high energy efficiency.

Control interface: Whether remote control, data recording and other functions are required.

After-sales service and technical support: The quality of the manufacturer’s after-sales service is also an important consideration when purchasing.
