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.

Basic Structure of Low Temperature Chiller

Industrial water chiller consists of compressor, condenser, evaporator, expansion valve and other accessories.

  1. Compressor: in the industrial water chiller system, the compressor is the power to ensure refrigeration. The compressor is used to increase the pressure of the refrigerant in the system and make the refrigerant circulate in the refrigeration system to achieve the purpose of refrigeration.
  2. Condenser: high temperature and high pressure Freon of the refrigeration system enters the condenser after coming out of the compressor, releases a lot of heat to the cooling medium, and then is cooled and liquefied.
  3. Evaporator: when the Freon liquid of the refrigeration system enters the expansion valve for throttling and is sent to the evaporator, it belongs to the vaporization process. At this time, it needs to absorb a lot of heat to gradually reduce the valence and mass temperature to achieve the effect of refrigeration and cooling.
  4. Expansion valve: in the refrigerant system flow chart of the industrial water chiller, we found that there is a small part between the outlet of the condenser and the inlet of the evaporator, which is called thermal expansion valve. It is a throttling and depressurizing part to reduce the condensation pressure of the refrigerant to the evaporation pressure. Therefore, its role in the refrigeration system is essential. It is connected with the refrigeration compressor, evaporator, condenser It is also called the four components of the refrigeration system.
  5. Other accessories: including drying filter and high and low pressure controller. The drying filter is non detachable. The internal structure adopts molecular sieve structure, which can remove a small amount of impurities and water in the pipeline, so as to purify the system. The high and low pressure controller plays a protective role in the refrigeration system.
