Central dehumidifier series
Central fresh-air and recirculating dehumidifier
GDS28BA / GDS58BA / GDS28BD / GDS58BD / GDS28 / GDS58 / GDS28B / GDS58B
Eight models cover fresh-air and recirculating dehumidification for different airflow and moisture loads.
- Dehumidification capacity reaches 100 L/day and fresh-air volume 500 m³/h.
- C4 models use corrosion-protected copper fins for demanding humid environments.
- Gravity drainage, app control and optional pump drainage or Modbus integration.

Product parameters
- Power supply220V/50Hz
- RefrigerantR410A
- Model configurationBidirectional total heat-recovery fresh-air dehumidifiers (GDS28BA / GDS58BA); unidirectional fresh-air dehumidifiers (GDS28BD / GDS58BD); C4 corrosion-resistant recirculating dehumidifiers (GDS28 / GDS58); standard recirculating dehumidifiers (GDS28B / GDS58B)
- Dehumidification methodBidirectional models dehumidify fresh air with total heat recovery; unidirectional models combine one-way air supply with recirculating filtration and dehumidification; recirculating models filter and dehumidify recirculated air.
- Filtration systemBidirectional models: G4 pre-filter + high-efficiency filter (grade pending confirmation); all other models: F9 medium-efficiency filter, upgradeable to H11.
- Cabinet materialBidirectional models: powder-coated cold-rolled steel with a 304 stainless-steel water tank; all other models: powder-coated 304 stainless-steel cabinet.
- Heat-exchanger finsC4 corrosion-resistant models (GDS28 / GDS58): copper fins with C4 corrosion protection; all other models: aluminium fins.
- DrainageGravity drainage; pump drainage available as an option.
- ControlApp remote control included; Modbus upgrade optional.
- Airflow directionLeft/right air inlet and outlet.
- Operating conditions10–35°C
- ApplicationsFresh-air dehumidifiers suit spaces that need fresh-air introduction; recirculating models suit enclosed high-humidity environments such as basements and swimming pools.
