The Fral professional portable dehumidifiers, FDNF - FDND series, are high-performance units. They feature a robust hot-dip galvanized sheet metal structure painted with epoxy resins and are mounted on four swivel casters for easy mobility. They include a high-efficiency washable and easily replaceable polyurethane filter and a very large condensate collection tray with the option for direct drainage. It is possible to replace the tray with a condensate lift pump that can pump condensate up to 3.5 m above the unit's installation level. A key feature of all Fral professional portable models in the FDNF - FDND series is the evaporator coil made of smooth aluminum tubes (except for the ECO model). This exclusive solution, derived from professional dehumidifiers, yields lower energy consumption and very high efficiency even at low relative humidity. All models include an hour counter and hot-gas defrost (ECO excluded).
