Unlike most suppliers, the Dantherm Group product ranges include both refrigerant AND desiccant drying equipment. With products that span both technologies, we can offer impartial advice that provides a solution specifically suited for your application.
The air to be dehumidified (process air), passes through a slowly rotating silica gel rotor. The desiccant material attracts the moisture to its surface, removing it from the air stream (dry air). A second, smaller air stream (reactivation air) usually heated to around 120°C, is required to remove the moisture from the rotor. This (wet) air must then be exhausted to atmosphere using a duct. Slowly rotating the rotor through both airstreams creates a continuous dehumidification process.
Generally, where a very low relative humidity or absolute humidity is required, and/or where the operating temp is below 3°C.
