Product Details

Applied to gas condensation liquefaction recovery. The exhaust gas or other electronic gases are connected to the equipment through the induced draft fan (vacuum pump), liquefied, collected and separated into the collection tank by lowering the temperature, and other gases are discharged, so as to realize the condensation, capture and recovery of the gas.


  • The gas heat exchange system has a pressure resistance of 8bar, and a heat exchange cold box with a pressure resistance of 25bar can be customized;
  • The temperature range is from -40°C to -75°C, which can meet different temperatures;
  • Environmentally friendly refrigerants are used;
  • Using the secondary subcooling technology, the refrigeration is rapid and the limit temperature is low;
  • Adopt well-known brand compressors, the main self-brands are Taikang, Emerson Copeland, and Carlisle;
  • The evaporator adopts a plate heat exchanger, which is small in size, long in residence time and high in efficiency;
  • Adopt cold control (Danfoss pressure controller, balance valve, solenoid valve, dry filter, Emerson oil separator, etc.);
  • Adopting Danfoss expansion valve and Emerson electronic expansion valve, the control precision is high;
  • Using Siemens PLC, 7-inch color touch screen display, automatic control operation, and with temperature, pressure curve display, temperature record U disk, fault alarm record;
  • The whole machine is installed, and the system has been tested in the factory. The user only needs to install the refrigerant pipeline and cooling water pipeline to run.
