Sorption dehumidifiers represent cutting-edge technology in moisture control. Unlike traditional methods, these devices utilize desiccant materials and a rotating rotor to efficiently remove moisture from the air. The process involves passing air through the rotor, where moisture is captured and subsequently removed by a hot air stream.

The Recusorb, Econosorb, and Frigosorb principles are all trademark protected according to Swedish Trademark Register and also European Patent and Trademark Register. The Frigosorb principle was patented in Sweden in 1996.

Recusorb R

Recusorb R operates using integrated heat recycling. During the rotor’s regeneration, heat is absorbed and then recycled in the “purge zone”, where incoming air is preheated and partly dehumidified. Energy consumption falls and the dry air becomes both drier and cooler compared to other sorption dehumidifiers.

Recusorb DR

Like Recusorb R, Recusorb DR has heat recycling but has a fan for both the dry airflow and the wet airflow. This makes installation simpler when you require overpressure in the room to be dehumidified. This principle is also suitable when you want to achieve very low dew points.


The Consorb principle is normally used at low regeneration temperatures, e.g. if you have surplus heat or when dehumidifying very damp air. The Consorb principle is also good when there is a large difference in moisture content between process and regeneration air inlets.


Frigosorb is a principle patented by DST. Frigosorb is used in applications where it is difficult to remove a wet air airflow. Thanks to the heat pump function Frigosorb is very energy-efficient, using approximately 1/3 of the total energy consumption of regular sorption dehumidifiers. sorption dehumidifiers.


Econosorb combines a heat pump with the sorption rotor in a unique way, providing very low energy consumption and low dry air temperature. Probably the most energy-efficient dehumidifier on the market, with approximately 1/4 of the total energy consumption of regular sorption dehumidifiers. Econosorb has both condensation and wet air.


Aquasorb basically functions as a Consorb but the wet air flow is condensed in an air-chilled condenser instead of being led out. No need for taking out wet air from the dehumidified room. All energy put into the unit stays also in the room which is good for drying applications.
