Desiccant rotor for dehumidification

The Dessica Silica Gel rotors are designed to be used in most environments for dehumidification applications with high performance and long life.
The Dessica Silica Gel rotors are also suitable for use in Desiccant Evaporative Cooling systems.
The process makes it possible to closely tailor the amount and characteristics of the Silica Gel in the rotor.
The capacity, pressure drop and other characteristics of the Dessica Silica Gel rotors can easily be calculated in our software program.

Dessica silica gel rotors properties

Material Composition: The rotor has a very high, 82%, active SilicaGel content and only 16% glass fibre content, the remaining 2 % is the Acrylic surface coating.
Fire resistance: The rotor has been tested according to ASTME test E-84 and achieved a flame index of 0 and a smoke produced of 0.
Technical properties: There is no limit for how high relative humidity the rotor can stand as long as droplets are not introduced into the rotor during operation. The rotor can be washed in water with weak non-alkaline detergent, after saturation in humid air.
Physical properties: The density of dry material is approx. 240 kg/m3. The media can pick up approx. 40% of it’s dry weight as moisture in humid environment. The surface compression strength of the rotor is more than 200 kPa.

On request DESSICA produce replacement rotors in sizes to fit most existing dehumidifiers.
