Built for heavy-duty drying, this Costway 85 L/day commercial dehumidifier is one of the higher-capacity options in the dehumidifier UK lineup, removing up to 85 litres of moisture per day and covering very large spaces up to 500 m². It is made for flood and water-damage restoration, drying paint on construction sites, indoor gardening, greenhouses and wine cellars rather than household rooms. The headline feature is the built-in pump teamed with a 7.6 m hose and a 4 m vertical lift, so waste water can be pushed up and out to a sink or drain for true continuous, unattended drainage. Power sits around 710 to 850 W depending on conditions, costing roughly 18p to 22p per hour at 26p/kWh, and as a compressor unit it only runs hard while humidity stays above your set point across the wide 10% to 90% range. Auto defrost keeps the coils clear in cool air, while auto on/off and memory restart mean it resumes your settings after a power cut, useful on long jobs. A collapsible handle, wheels and a washable filter keep the 38 kg unit portable and low-maintenance. In the box: the commercial dehumidifier, drain hose and instruction manual.

Commercial Dehumidifier 85L/Day with Pump and 24H Timer — FAQs
What size space does the 85L pump dehumidifier cover?
It handles very large spaces up to 500 m², suiting flood restoration, construction drying, greenhouses and wine cellars. Extraction is up to 85 L/day at 35°C/80% RH, falling to around 40 L/day in milder 27°C/60% air.
How much does this dehumidifier cost to run per hour?
It draws roughly 710 to 850 W depending on conditions, so at about 26p/kWh expect around 18p to 22p per hour at load. The compressor cycles off once your target humidity is met, reducing real-world cost.
How does the built-in pump drainage work?
The integrated pump uses a 7.6 m hose and can lift water up to 4 m vertically, so it can drain continuously into a higher sink or window drain without manual tank emptying.
Does it restart after a power cut?
Yes. Memory restart and auto on/off mean it resumes your saved settings automatically after power is restored, which is valuable for unattended overnight or multi-day drying.
What's included?
The box contains the commercial dehumidifier, the drain hose and an instruction manual. The pump, washable filter, wheels and collapsible handle are built in.
