For the toughest drying jobs, this Costway 120 L/day industrial dehumidifier is the highest-capacity unit in the dehumidifier UK lineup, stripping up to 120 litres of moisture from the air per day (at 35°C, 90% RH) across very large spaces up to 500 m². It is built for warehouses, factories, basements and construction sites, not homes, with a powerful 750 m³/h airflow that circulates air through big, open floor plans fast. A wide 10% to 98% humidity range and a 25 to 56°C operating range let it cope with demanding, high-heat conditions other units cannot. Drainage is fully hands-free: the included 100 cm hose enables continuous auto gravity drainage, so there is no tank to empty during long jobs. Power scales with conditions from 1100 W up to 1500 W, costing roughly 29p to 39p per hour at 26p/kWh at full load, with the compressor cycling off once humidity drops below your set point, sensible for an industrial-grade machine. A digital display control panel keeps operation simple, while four universal wheels and two built-in handles make the 42 kg body manoeuvrable across rough site flooring. In the box you get the industrial dehumidifier, drain hose and instruction manual, ready to dry out flood damage, fresh plaster or persistent industrial damp.

What size space does the 120L industrial dehumidifier cover?
It handles very large spaces up to 500 m², such as warehouses, factories, basements and construction sites. Extraction is up to 120 L/day at 35°C/90% RH, around 47 L/day in milder 27°C/60% air.

Power ranges from 1100 W to 1500 W depending on conditions, so at about 26p/kWh expect roughly 29p to 39p per hour at full load. The compressor cycles off once your set humidity is reached, reducing real cost.
Does it need emptying?
No. The included 100 cm hose provides continuous auto gravity drainage, so there is no tank to empty, which suits long unattended drying jobs on site.
What humidity and temperature conditions can it handle?
It offers a wide 10% to 98% humidity setting range and operates across 25 to 56°C, making it suitable for demanding, high-heat industrial and restoration environments.
