Description

The Sealey SDH20 Dehumidifier is a professional-grade moisture control unit ideal for workshop environments, drying out flood-damaged properties, and eliminating damp in storage areas. With the capacity to extract up to 20 litres of water per day, this compact and portable dehumidifier effectively prevents the build-up of mildew and mould that can damage tools, materials and equipment. Designed for trade and commercial use, this dehumidifier features an intuitive touchscreen control panel that allows precise adjustment of humidity levels and timer settings from 1 to 24 hours. The front panel indicator light changes colour to display the current humidity level in the room, providing instant visual feedback. The unit is suitable for spaces up to 30m² and operates efficiently in temperatures between 5-32°C, making it versatile for year-round use. The SDH20 includes a dedicated laundry mode function that accelerates drying cycles, particularly useful in site welfare facilities or trade workshops where workwear needs to be dried quickly. For continuous operation, the unit comes supplied with a 300mm drain hose that eliminates the need to manually empty the 6.5-litre condensate tank. Four swivel wheels ensure easy manoeuvrability between work areas, whilst the automatic shut-off function activates when the tank reaches capacity for safe, unattended operation. The dehumidifier uses environmentally friendly R290 refrigerant, demonstrating compliance with modern environmental standards whilst delivering a maximum airflow of 195m³/hr for efficient moisture extraction.
