Dehumidification Systems

DehuTech AB is the export division of the Swedish desiccant dehumidifier manufacturer, Fuktkontroll AB. Fuktkontroll AB has been active in the domestic Swedish market since 1980; marketing, selling and manufacturing desiccant dehumidifiers and turn key dehumidification systems. The desiccant rotor, which is a patented rotor, is manufactured in Sweden. Avon Electric Ltd are the sole agents for DehuTech equipment in New Zealand. Unlike standard refrigerant dehumidifiers the Dehutech range of dessicant dehumidifiers will operate efficiently at low temperatures allowing for a much broader scope of application.

The Dessicant (Absorption) Dehumidification Process

The dehumidifiers are of the solid wheel desiccant type and operate with two air streams. One larger air volume which is to be dehumidified, and one considerably smaller air volume for reactivation of the desiccant rotor.

As the larger air volume (process air) passes through the rotor, which is in a continuous slow rotation, the water vapour is adsorbed by the rotor material.

This reduces the humidity of the process air which will leave the dehumidifier as dry air.

To remove the moisture captured in the desiccant rotor, the smaller air volume (reactivation air) is heated before re-entering the rotor.

This warmer air is passed through a small segment of the rotor, the rotor material gives away its moisture (desorbs) to the warm air stream.

The moisture will leave the dehumidifier as wet air, to be exhausted outside the space that is to be humidity controlled.

DehuTech dehumidifiers compromise a unique patented desiccant rotor, giving the unit high moisture removal capacity, low running costs and reliable operation.
