DVS is an EEV controller developed to enable precise control of superheat, capacity control, hot gas bypass, etc. by applying an electronic expansion valve, which is a key expansion device in refrigeration, cooling, heat pump and refrigeration application cycles.

  DVS consists of a controller, pressure sensor, temperature sensor, and electronic expansion valve, and can be applied to various places such as refrigeration (air conditioning), cooling, heat pump, low-temperature warehouse, showcase and other applications.

  Applying various expansion valves such as Denfoss, Spolen, Emerson, Oxide, Dunhan, Sagnomiya, etc. (unipolar and bipolar board) DVS supports various operation modes.

▶ DVS supports various operation modes.

  - Super heat (superheat) proportional control operation mode

  - Manual control operation mode

  - Forced control operation mode

▶ Both unipolar/bipolar type EEV are applicable. (Siemens magnetic MVL 661 series applicable)

▶ With RS485 communication (MODBUS) function, it is easy to interface with other devices.

※ Refrigerants other than DVS's currently available refrigerants (R22, R23, R134, R404, R407, R410, R744) can be applied when ordering.

    DVS includes controller, pressure sensor, temperature sensor, and transformer / DVD includes controller and transformer

    EEV is sold separately. (Optional purchase by capacity)
