Desiccant dehumidifiers, which work effectively at lower temperatures than refrigerant-based units, are gaining ground in cold-weather restoration applications where traditional dehumidifiers are less effective, according to industry equipment specialists.
Refrigerant-based dehumidifiers, which are the most common type used in restoration work, lose efficiency at temperatures below about 65 degrees Fahrenheit and may stop working entirely at temperatures below freezing. This limitation is a significant challenge for restoration work in cold climates or in unheated structures during winter months.
Desiccant dehumidifiers use a moisture-absorbing material (typically silica gel) to remove water vapor from the air, and they work effectively at temperatures well below freezing. This makes them particularly valuable for restoration work in cold climates and for winter storm damage restoration.
The active winter storm season in early 2026 has driven increased interest in desiccant dehumidifiers among restoration contractors in northern states, who have encountered limitations with refrigerant-based units in cold, unheated structures.
Leading manufacturers of desiccant dehumidifiers for the restoration market include Dri-Eaz, Munters, and several other companies that offer a range of capacities and configurations for different restoration applications.
