Desiccant type dehumidifiers are designed for efficient dehumidification of air with humidity up to 100% and temperature
from -20 °C to + 40 °С with minimum amount of energy consumption. The temperature range from -30 °C to + 50 °C is also
achievable with a special request.
Usually dehumidifiers of this type are used if a humidity of less than 30% is required in the premise and /or the air
temperature is less than +10 °C since condensation dehumidifiers become ineffective in such conditions.
DanVex AD dehumidifiers are used for indoor or outdoor installation where air
humidity regulation is required independently or in combination with a ventilation and
air treatment system.
The principle of operation is to use a moisture-absorbing rotor with high adsorbing properties. Air supply
to the rotor is carried out in such a way that the operating (dehumidified) air passes through 75% of the rotor
sector and through 25% of the sector in the counterflow to the working one - the regeneration air preheated
to a predetermined temperature. This air absorbs moisture from the rotor sorbent and withdraw it outside the
room under dehumidifying.
Slight overpressure of water vapor contributes to the efficient exchange of humidity between air and
sorbent and the quality of regeneration is controlled by the temperature of the regeneration air. In addition the
regeneration air performs the function of cleaning the inner surface of the rotor from possible contamination
due to dust ingress together with the operating air. The rotor rotation allows you to combine the process of
operating air sorption with the regeneration of the sorbent.
