Refrigeration unit

Product Features：

• Temperature range from -10℃ to -45℃，available for customization to meet different temperature requirements.

  All use environmentally-friendly refrigerants.

  Single machine cascade refrigeration, rapid cooling, low cooling temperature.

  Utilizing imported semi-hermetic piston compressors, primarily from brands such as Bitzer, LEYBOLD, Turbocor, and Emerson; evaporators are equipped with plate heat exchangers for compact size and high efficiency; shell and tube heat exchangers are corrosion-resistant and capable of withstanding saltwater corrosion.

  Utilizing renowned brand names in the industry (pressure controllers, balancing valves, expansion valves, solenoid valves, drying filters, Guanyu oil separators, manometers, check valves, etc.).

  The engine cooling water circuit uses recirculated water for reuse, thereby conserving water.

  Utilizing Emerson electronic expansion valves, high control accuracy is achieved.

  Touchscreen display for automated control operations, featuring temperature curve display, temperature recording, fault alarm logging, and data exportable to USB drives for saving.

  High capacity refrigeration units are equipped with semi-hermetic screw compressors. Electronic expansion valves ensure high efficiency and energy saving.

  Complete installation, the system has been tested at the factory; the user only needs to complete the installation of the refrigerant piping and cooling water piping before operation.

  Factory Testing: Each refrigeration unit operates continuously for over 12 hours in the factory.
