Unique micro drying solution for OEM industrial and commercial applications

Rosahl is a revolutionary solid-state micro dehumidifier specifically designed for drying small enclosures of up to 8m³ (280 cu ft).  The unique polymer membrane removes moisture through electrolysis. It needs no maintenance, has a low running cost, is very compact and has a long service life.

ROSAHL was developed by Mitsubishi Electric Corporation Group member Ryosai Technica Company in Japan in response to a demand for compact maintenance free, air drying solutions to protect sensitive equipment and from moisture damage.

It has since found its way into applications such as protecting museum display cabinets, telecommunications equipment, manufacturing processes and electrical cabinets.  The smallest model is 25% the size of an AA battery and requires only a 3 Volt dc supply.

It is available as a membrane only or supplied complete with housing and suitable for a 110/220V power.  Rosahl is capable of drying to below 10% RH and is also suitable as a humidifier.
