Keyword Recirculating Chiller Ultra-low Temp Chillers SUNDI series TES series Products

Product Details


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.

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