TL;DR
A desiccant dehumidifier is a drying machine that strips moisture from air by passing it over a slowly rotating wheel coated with adsorbent silica, rather than condensing it on cold refrigerant coils. Because it works without a condensation cycle, it keeps performing in cold spaces and at low humidity levels where refrigerant units stall, and it can deliver air at extremely low dew points.
What it means
A desiccant dehumidifier is a drying machine that strips moisture from air by passing it over a slowly rotating wheel coated with adsorbent silica, rather than condensing it on cold refrigerant coils. Because it works without a condensation cycle, it keeps performing in cold spaces and at low humidity levels where refrigerant units stall, and it can deliver air at extremely low dew points. Restoration contractors deploy these on dense, slow-drying materials, hardwood floors, plaster, framing lumber, and the daily rental rate on the drying log will read higher than a standard LGR dehumidifier's.
