FEATURES:
The product adopts the international brand compressor Carlyle, which is small in size and high in efficiency. The single compressor can realize the temperature control of -152 °C, and the ultra-low temperature refrigeration technology is at the international advanced level.
1. To save water resources, it is possible to use the glycol-water mixture to carry out circulating refrigeration, strict circulation pipeline design, prevent circulating water pollution, and prolong the use time of circulating water;
2. Original imported compressor, overlapping supercooled refrigeration technology;
3. Double condensation high efficiency system;
4. Computer cascade temperature controller, temperature digital display, adjustment unit 0.1 degree, PT100 temperature sensor, -125°C~ -20°C wide temperature range;
5. Ambient temperature monitoring function to prevent the system operating environment temperature from being too high;
6. It adopts full-closed design, no water absorption during low-temperature operation, ensuring the purity of cold and heat-conductive medium, preventing ice crystals and improving the life of thermal fluid.


Cryogenic circulators, a very wide refrigeration temperature range, and a controllable temperature of -150 degrees to -5 degrees. It adopts secondary subcooling, fast cooling speed, safe and reliable, and is used for rapid liquid cooling. It is widely used in high-tech industries such as petrochemical, medical, pharmaceutical, biochemical, freeze-drying, pharmaceutical and so on.
