We have models available in a range of sizes, suited to home use, commercial use and industrial use. These dehumidifiers perform well in cold conditions - even well below freezing. We have models ideal for use in basements and attics, cellars, gyms, garages, construction sites, aircraft, boats and more.
How Does a Desiccant Dehumidifier Work
Desiccant dehumidifiers feature desiccant material, assembled in a corrugated formation on a rotating wheel. A fan draws air into the dehumidifier through a vent and passes it through the rotating desiccant wheel. The desiccant absorbs moisture from the air like a sponge and the dry air is blown out of the dehumidifier through another vent.
The saturated desiccant wheel continues to rotate around, where a stream of reactivation air and a heating element are used to dry out the desiccant, so that it can absorb more moisture. Moisture evaporates from the desiccant and is removed from the unit as water vapour, via another vent.
Lengths of ducting can be fixed to the inlet and outlets on desiccant dehumidifiers. When ducted, they can be placed inside the area that needs to be dried and the moisture vented outside, or the unit can be placed outside the space, the humid air removed from the space and dry air vented back in.
Where To Use a Desiccant Dehumidifier
Desiccant dehumidifiers are much more effective at drying in lower temperatures and lower humidity environments - they even work effectively in temperatures well below freezing. They are perfect for use in unheated spaces, challenging cold climates, and for applications where a low relative humidity or absolute humidity level is required. They are often used in cold storage areas, basements, boats, aircraft, construction sites, and specialist manufacturing and food production & manufacturing applications requiring a low relative humidity level.
The Advantages of a Desiccant Dehumidifier
- High moisture removal rate in a single air pass
- Effective in very low temperatures - well below 0 degrees
- Effective in low humidity environments
- Capable of achieving very low absolute humidity levels
- Small, compact & portable
- Versatile installations with different ducting options
Disadvantages of Desiccant Dehumidifiers
- Higher energy consumption than refrigerant dehumidifiers
- Higher running costs than refrigerant dehumidifiers
- Low specific moisture extraction (kg/kWh)
- Ducting required from/to outside for reactivation air and wet air
Take a look at our range of desiccant dehumidifiers available to order online or over the phone. Our range includes models from some of the best brands around – including Aerial and Ecor Pro.
Models such as the Ecor Pro DH800 are perfect for home use, in attics and basements, while models such as the Aerial ASE 200 are ideal for construction sites and renovation projects. Desiccant dehumidifiers are so effective at extracting moisture in challenging conditions - the Ecor Pro DH 1200 was even named as the 'Best Boat Dehumidifiers' by Yachting World Magazine.
