Protecting what you value

Rosahl is a unique family of electric micro-dehumidity controllers for enclosures where maintenance-free drying is an key factor.

The Mitsubishi Electric Corporation in Japan developed Rosahl. It was in response to demand for compact and maintenance free air-drying solutions to protect sensitive equipment from moisture damage. It has since found its way into a wide range of other uses. These include for protecting museum display cabinets, telecoms. equipment, LED lighting, lasers, instrumentation, and electrical cabinets and more.

Rosahl membranes fit a wide variety of applications and environments from -20° to +50° C

Understanding Our Technology

How Our Dehumidifiers Operate

1

Step 1: Electrolysis

When 3 Volts D.C. is applied to the SPE’s electrode, the moisture in the enclosure is attracted to the membrane where it breaks down into hydrogen ions and oxygen. 

2

Step 2: Ionic Membrane Action

The hydrogen ions (not hydrogen gas) migrate through the membrane for discharging on the outside where they react with oxygen in the air, to form water vapour.

3

Step 3: Enclosure is dehumidified

With zero air exchange, the process removes the moisture in the enclosure in the enclosure to the required level. It is maintenance free and inexpensive to run.
