The manufacturing of sweets can be a sticky process and Calorex desiccant dehumidifiers can help to maintain crucial humidity levels throughout the production process. Calorex desiccant units are ideal for low temperature and low humidity operation and are suitable for a number of applications.

How Calorex adsorption dehumidifiers work

At the heart of all Calorex DehuTech adsorption dehumidifiers is a slowly rotating rotor which is impregnated with desiccated silica gel. This rotor is divided into sections by stationary baffle plates and seals which are fixed into the housing of the dehumidifier. When air to be dried is passed across the process sector of this rotor, moisture is adsorbed from it by the silica gel.

In order to allow the dryer to continually adsorb moisture, preheated ambient air is drawn across the rotor’s regeneration sector. As this air passes across the silica gel contained within this section, it removes the trapped moisture. This moisture laden air is then rejected to outside. The regenerated silica gel is then slowly rotated back into the process air stream, allowing the dehumidification process to operate on a continuous basis.

Reliable – low maintenance cost

Due to their design, maintenance is simple. Perhaps more importantly, the design is inherently reliable, ensuring many years of trouble free service.


Easy installation with each dehumidifier is fully packaged, factory tested and is supplied with duct spigots, air filters and safety circuits.
Wide operating range effective dehumidification down to -30°C and 0% RH with either electric, steam or direct fired gas regeneration enabling us to specify the most energy efficient option.

Calorex also manufactures refrigerant dehumidifiers in a range of sizes from the smaller wall unit to the large floor standing industrial sized system. Whatever you need, Calorex will have the solution.

All products are supported by an in-house applications department and nationwide service network.
