High and low temperature circulation device are a type of multifunctional device which own heating and cooling function to provide constant temperature for chemical experiment. This  electrical high and low temperature circulation device has been widely used in medical, chemical and biological industries. The electrical high and low temperature circulation device has two systems: cooling system and heating system. These two systems can work together or independently.

The whole system is a closed liquid circulation system with the expansion of container, expansion of the container and the liquid circulation is adiabatic and did not participate in liquid circulation, only mechanical connection, regardless of the temperature of liquid circulation is a high temperature or low-temperature expansion of the medium container of low at 60 degrees.

Throughout the liquid circulation system is sealed, the low temperature did not absorb water vapor, high temperature did not produce the oil miss The entire circulatory system is not used in machinery and electronic valves.

Main Features

1.Using American Valley Wheel Emerson, France hundred years Taikang, Germany Danfus and other brands of imported compressors.

2.The whole liquid circulation is a fully enclosed system. The thermal conductive fluid is not volatile and oxidized at high temperature. It is not easy to absorb the moisture in the air at low temperature, extend the service life of the heat transfer fluid, and the oil change is not required during heating and cooling.

3.Plate heat exchanger is used in refrigeration and heat exchanger, which has high heat transfer coefficient, large heat transfer area per unit volume, small heat loss and 35% higher heat transfer ratio than that of coil tube.

4.Liquid level display function, monitor liquid level at any time, avoid lack of liquid.

5.Digital explicit temperature control, PID temperature control technology, overtemperature power cut-off and dry burning protection function is simple to operate.

6.The temperature probe is PT100 sensor.
