High and low temperature cycling device can provide circulating device of cold source and heat source.

It is widely used in medical, chemical and biological industries. It has three systems: refrigeration system,

heating system and pre-cooling system. The three systems can work together and independently.

2. Features:

1) Use original famous compressor of international famous manufacturers.

2) Wide temperature control range, users don’t need to change the heat-conducting medium which reduces

    medium consumption;

3) Totally sealed circulating system, avoid volatile and oxidation of heat-conducting liquid at high

     temperature,can also keep the device from absorbing the water in air at low temperature, thus prolong

     the service life;

4) Refrigeration and heat exchanger uses blazed plate heat exchanger, small volume, and high working efficiency;

5) Liquid level LCD display function, can monitor the liquid position and avoid liquid shortage;

6) The pre-cooling uses force air cooling, save water.
