LNEYA specializes in the production of single-fluid cryogenic chillers. The temperature ranges of low temperature chiller is from -150°C to -5°C, which can meet the needs of different refrigeration temperatures. Low Temperature chillers are widely used in chemical, pharmaceutical, biochemical and other industries in the field of low temperature reaction, refrigeration speed, safety and reliability. 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.
