Desiccant Dehumidification

Desiccant Dehumidification

A Desiccant Dehumidification system consists of a desiccant wheel which rotates through a supply and regeneration air stream. In the supply air side the desiccant wheel removes moisture from the air stream by absorption. As it rotates into the regeneration air stream it is subjected to hot air. This hot air absorbs the moisture picked up on the supply side and exhausts it to atmosphere.

We can utilize resistance electrical heaters, Direct or Indirect fired Natural Gas, or Steam as the regeneration heat medium.

All the heat from the regeneration side of the process does not get exhausted to atmosphere. As the hot desiccant media rotates into the supply side air stream unwanted heat is put into that air stream.

Depending on the application a post-cooling coil is typically required
