the basic principle of Ultra-Low Temperature 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. Temperature control range down to -150°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. 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.

Features of Ultra Low Temperature Chillers

• the ultra-wide temperature control range can meet the temperature requirements of different industries.
• Secondary subcooling technology is adopted, with fast refrigeration speed.
• Imported semi closed piston compressor, semi closed piston two-stage compressor and semi closed screw compressor are adopted. the evaporator adopts high force plate heat exchanger, which has small volume and high efficiency.
• A full set of imported cold controls (Danfoss pressure controller, balance valve, expansion valve, solenoid valve, drying filter, Emerson oil separator, alco sight glass, check valve, etc.) are adopted.
• Danfoss electronic expansion valve is adopted with high control accuracy.
• Siemens PLC S7-200 / 300 controller, LNEYA touch screen display, automatic control and operation, temperature curve display, temperature record can be exported to USB flash disk, fault alarm record and other functions are adopted.
• the large refrigerating capacity equipment adopts semi closed screw compressor with economizer operation, which is combined with electronic expansion valve to ensure high efficiency and energy saving.
• Factory test: the load test of each equipment in the factory shall not be less than 12 hours.
