How does a desiccant dehumidifier work?
Due to their ability to operate at low temperatures and achieve precise levels of relative humidity, desiccant dehumidifiers are a top choice for food manufacturers throughout the UK. Here’s how they work:
- A desiccant rotor within the machinery contains a network of small airways lined with silica gel
- Humid air from the environment is pulled into the desiccant wheel. The silica gel absorbs the moisture, and releases around 75% of the air out warm and dry
- The other 25% of “reactivation air” is heated to around 120°C, removing moisture from the rotor. Wet air is released into the atmosphere through a duct, ending a continuous process of both airstreams passing through the rotor
- High moisture removal rate in a single air pass
- Achieve very low absolute humidity levels
- Can operate in low temperatures and at low humidity
