Low Temperature Chillers

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.

We 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 Low Temperature Water Chillers

The ultra-wide temperature control range can meet the temperature requirements of different industries.
Adopt environmental protection refrigerants.
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.
Generator cooling water circuit use intermediate heat exchanger, improve system reliability and safety.
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.
Offer machine installation and system test, users only need to finish the installation of refrigerant and cooling water.
Factory test: the load test of each equipment in the factory shall not be less than 12 hours.

Advantages of Low Temperature Water Chillers
