DFLEX series

Desiccant rotor dehumidifiers 

Select your need


DFLEX desiccant dehumidifiers are very similar in operation to the DFRA desiccant rotor dehumidifiers. They are also based on a high-performance silica gel desiccant rotor for water vapour retention, but have a higher flow rate and drying capacity. In addition, these desiccant dehumidifiers are characterised by a modular and flexible construction which makes them a perfect choice for air dehumidification in a multitude of applications.

Dehumidification systems are necessary for many industrial processes in which excess relative humidity can cause problems in the preservation of certain products or materials or reduce their quality. This is the case in the refrigeration industry, food industry, archives or museums, etc. They are also used on many occasions to improve the domestic environment in areas where humidity values are very high.

The dehumidification process in this type of desiccant dehumidifiers consists of the absorption of humidity molecules from the air by a desiccant rotor. Once they have been absorbed, the air is then blown back to a much lower dew point.
