Aerial AD 740: Mobile Dehumidifier for Construction Drying and Water Damage Restoration
The Aerial AD 740 mobile construction dryer is designed for anyone who needs powerful and reliable dehumidification. With a dehumidification capacity of up to 34 litres per day (at 30 °C / 80 % RH), this condensation dehumidifier is suitable for water damage restoration and construction drying as well as for storage rooms, basements, garages, archives and waterworks.
The AD 740 belongs to the same series as the Aerial AD 20 mobile dehumidifier, but is designed for larger rooms: according to the manufacturer, it is suitable for heated rooms up to 500 m³ and unheated rooms up to 350 m³ (practical values for storage rooms). Condensate is collected in a 6.8-litre container; the unit switches off automatically when the container is full. Alternatively, direct drainage via a hose is possible, and with the optionally available pump kit, autonomous operation is also possible.
Key features at a glance:
- Dehumidification capacity: 34 l/day at 30 °C / 80 % RH, 18 l/day at 20 °C / 60 % RH, 14 l/day at 15 °C / 60 % RH.
- Robust housing: shock-resistant, UV-resistant plastic housing in AERCUBE® design with a durable, easy-to-clean surface; easy to open, clean and maintain.
- Mobile and stable: two plastic wheels (Ø 190 mm) and a folding handle; high stability even during operation. Can be combined with all units of the AERCUBE® series, with fixing points for the AERCUBE® lashing system.
- eDRY® control: multilingual electronics with target humidity setting (retained after power disconnection), two fan speeds, continuous and night mode, display of operating hours and actual/target humidity, "tank full" indicator light.
- Calibrated energy meter: MID-compliant, non-resettable and readable even without power, practical for billing electricity consumption during construction drying.
- Operational reliability: demand-controlled hot gas defrosting and automatic restart after a power failure.
- Power consumption: 625 W at 30 °C / 80 % RH, 480 W at 20 °C / 60 % RH, 415 W at 15 °C / 60 % RH; maximum 800 W.
