Product Description

The Sealey SDH90 is an industrial-grade dehumidifier designed for professional moisture control in large commercial and industrial spaces. With a powerful extraction capacity of up to 90 litres per day, this heavy-duty unit effectively removes excess moisture from the air, preventing the build-up of mildew and mould in challenging environments. Ideal for construction sites, warehouses, and water damage restoration work, the SDH90 operates efficiently across working spaces of 90-200m³. The modern digital display provides real-time monitoring of both air humidity and ambient temperature, allowing precise environmental control. Its R290 refrigerant offers environmentally responsible operation with minimal global warming potential, making it suitable for contractors working to sustainability requirements. The unit features an 11-litre condensate tank with automatic shut-off when full, or alternatively can be connected to a drain hose for continuous unattended operation. The auto-defrost function ensures reliable performance even when room temperatures fall too low, whilst the 24-hour timer allows for delayed starting and programmed shut-off. Mounted on castors for easy repositioning around site, the dehumidifier includes a washable air filter for straightforward maintenance and sustained performance.
