Dantherm Aerial WT 280 – Indoor Air Laundry Dryer and Dehumidifier (79.2 l/day)
Available to order: typical lead time 5–10 working days. We confirm the exact date after your order or enquiry.
The Dantherm Aerial WT 280 is a wall-mounted indoor air laundry dryer that also works as a room dehumidifier. Instead of a conventional tumble dryer, it removes moisture from the room air and dries laundry in closed rooms all year round, independent of the weather. It is designed for up to 20 kg of dry laundry, can dehumidify closed rooms of up to 900 m³ (360 m²), removes up to 79.2 l/24 h at 30 °C / 80 % RH and moves 920 m³/h of air. The manufacturer states a drying time of 05:13 h:min and an energy consumption of 0.3 kWh per kg of laundry.
How it works
The WT 280 works on the condensation principle: room air is drawn in through the air filter, moisture condenses on the evaporator, and the dried air is returned to the room via the outlet, whose pivotable baffle plates let you direct the drying air. The condensate is discharged via a 15 x 2 mm drain hose. If ice builds up on the evaporator, the demand-controlled automatic hot-gas defrosting keeps the unit running at low temperatures.
The operating panel with display offers three laundry programmes: "cupboard dry", "iron dry" and "predried". Pressing a programme button for 5 seconds starts a time-limited drying run of 30, 60 or 90 minutes, and a fast-drying button is also available. With the ES button the unit switches to room dehumidification mode, in which the desired room humidity is set in 5 % steps starting at 35 %. The display language can be set to German, French, Italian or English.
Key benefits
- Laundry drying and room drying in one unit — dries up to 20 kg of laundry and keeps closed rooms of up to 900 m³ dry.
- Space-saving wall mounting — mounted on the supplied wall rail, the unit stays off the floor.
- Robust construction — galvanised sheet steel housing with an easy-care plastic cover.
- Durable refrigeration technology — hermetic rolling piston compressor, condenser and evaporator made of copper tubes with aluminium fins, and a service-friendly refrigerant circuit with integrated service connector.
- Energy-efficient EC radial fan — for a low power consumption of the air circulation.
- Operation at low temperatures — demand-controlled hot-gas defrosting keeps the unit working when ice forms on the evaporator.
- Easy filter care — the air filter is easy to remove and can be cleaned with water or manually.
