What are the technological requirements of the small high and low temperature circulating temperature controller

The small high and low temperature circulating temperature controller is used in the pharmaceutical and chemical industry to heat up to the temperature required by the process through electric heating, and indirectly transfer heat in the mode of circulating pump phase to make the temperature meet the requirements of the production process.
It is an industrial temperature control device.
control equipment

The small high and low temperature cycle temperature controller is composed of heating and cooling system, power transmission system, liquid level control system, temperature sensor, injection port and other devices because of different heat transfer media
.

Typically, the temperature sensor measures the temperature of the thermal fluid and transmits the data to the controller of the control section, which regulates the temperature of the thermal fluid, thereby indirectly regulating the temperature
.

If the small high and low temperature cycle temperature controller is in production, and the temperature of the equipment exceeds the set value of the controller, the controller will open the solenoid valve and connect the water inlet pipe until the temperature of the hot fluid, that is, the temperature returns to the set value
.

If the temperature is lower than the set value, the controller will turn on the heater
.

The reason for the high-pressure alarm condition of the small high-low temperature cycle temperature controller: because the equipment cooler is stopped or the water flow is insufficient, or the temperature of the water leakage is too high, the working pressure of the exhaust pipe of the refrigeration compressor may be too high, and a high-pressure alarm will appear.
The heat dissipation of the heat pipe is not good, there is non-condensable gas in the system software, and a part of the refrigeration pipeline is blocked, which causes the suspected working pressure of the refrigeration system to be too high, and a high pressure alarm occurs
.

The main purpose of the small high and low temperature cycle temperature controller is to heat the equipment that the customer needs to heat to the required temperature and keep the temperature constant
