Ventilation

Dehumidifiers

Control moisture before it controls your building.

A dehumidifier removes excess moisture from indoor air using a refrigeration cycle: humid air is drawn across a cold evaporator coil, causing moisture to condense and drip into a collection tray or drain. The now-drier air passes over a condenser coil where it is reheated slightly before being returned to the room — drier, but at approximately the same temperature.

Unlike air conditioning, dehumidifiers are focused solely on humidity control rather than temperature. They are particularly valuable in basements, storage areas, heritage buildings with rising damp, and coastal or high-humidity environments where mould and structural moisture damage are ongoing concerns.

Commercial dehumidifiers can process large volumes of air for industrial drying, document storage, swimming pools, and water damage restoration. Portable units serve targeted residential or commercial applications.

Applications

Common Installations

Basements & Subfloors

Prevents rising damp and mould in below-ground or poorly ventilated spaces.

Heritage Buildings

Controls moisture in thick masonry walls prone to condensation and salt damp.

Coastal Properties

High ambient humidity environments benefit significantly from continuous dehumidification.

Swimming Pool Halls

Industrial dehumidifiers manage evaporation from pool surfaces.

Archive & Document Storage

Maintains stable humidity for preservation of paper, artworks, and materials.

Water Damage Restoration

High-capacity units accelerate drying after flood or leak events.
