DVS-SL
manual
Product specification
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)
