Parameters Detailed

LNEYA specializes in the production of single-fluid cryogenic chillers. The refrigeration temperature ranges from -150°C to -5°C, which can meet the needs of different refrigeration temperatures. The company developed a direct-cooled ultra-low temperature chiller, using international brand compressors Carrier, using automatic cascade refrigeration mode and mixed refrigerants, within 3 minutes can be refrigerated to minus 120°C.

Offer machine installation and system test, users only need to finish the installation of refrigerant and cooling water.

Widely used in chemical, pharmaceutical, biochemical and other industries in the field of low temperature reaction, refrigeration speed, safety and reliability.

Working Principle

1.The basic principle of Ultra-Low Temp. Water-Cooled Chiller is that under ultra-low temperature, the movement of molecules is slowed down until the surface of the trapped and frozen cryogenic coiled tubes is slowed down, and the vapor is easy to be arrested, set and frozen, and the capture rate is high.

2.The secondary supercooling technology is adopted, with rapid refrigeration and low temperature.

This model is a water-cooled chiller. Refrigerant lines and cooling water lines need to be installed.
