What is a circulation thermostat?

A circulation thermostat is an instrument commonly used in laboratories or industrial production. Its main function is to control the temperature of liquid or gas so that it can reach a constant temperature. Through the thermostatic circulator, the temperature can be accurately controlled to avoid the impact of temperature fluctuations on experiments or production, ensuring the accuracy of experiments and the quality stability of products.

How does a circulation thermostat work?

A circulation thermostat is mainly composed of circulation pump, thermostat, temperature sensor, heating element and other components. Among them, the circulation pump is used to circulate liquid or gas so that it can reach a constant temperature. The thermostat controls the heating power of the heating element by continuously detecting the temperature signal fed back by the temperature sensor, so that the temperature of the liquid or gas reaches the set value and is maintained near this value.

The working process of circulation thermostat is as follows:

1. The circulation pump draws the liquid or gas out of the container, and then heats it through the heating element to reach the set temperature;

2. The temperature sensor continuously detects the temperature changes of the liquid or gas and transmits the temperature signal to the thermostat;

3. The thermostat controls the temperature of the liquid or gas within the set temperature range by adjusting the heating element;

4. At the same time, the circulation pump re-injects the constant-temperature liquid or gas into the container to be controlled, forming a constant-temperature cycle process, so that the temperature of the liquid or gas can be kept constant.

Features of circulation thermostat

The temperature control adopts PID method with high control accuracy.

The temperature display adopts digital display.

Internationally renowned brand compressor.

The circulation pump operates with double impellers, increasing the flow rate and lift.

The circulating liquid forms a dispersed and uniform flow field in the internal circulation, and the heat exchange is smooth.

The sink material is 304 stainless steel.
