Rosahl is a unique electric micro-dehumidifier for enclosures where maintenance-free drying is an important factor. It uses a solid polymer membrane (SPE) installed in a flat panel. A range of membrane sizes is available for enclosures volumes from one litre up to 4m³ (140 cu ft.) in volume.
Operation
Rosahl dehumidifiers work by electrolysis when supplied from a suitable 3V D.C. power supply. They act like an ionic pump to remove water vapour at a molecular level, without involving liquid water.
Importantly, no liquid water means no cleaning, no draining and no maintenance. With low running costs, they are suitable for use in remote locations, and where a conventional dehumidifier is difficult to maintain or to service.
Applications
Ryosai Technica (part of Mitsubishi Electric group of companies) developed and manufacture the Rosahl portfolio. It was in response to demand for compact and maintenance free air-drying solutions to protect sensitive equipment from moisture damage.
Applications range from storage areas for sensitive equipment through to challenging or remote external environments, and many other uses. Rosahl is a low energy moisture extraction system and has a low capacity relative to larger conventional (condensing) dehumidifiers. The process does not involve liquid water. So, unlike condensing humidifiers, they require no cleaning or draining: unlike silica gel, they do not require regular recharging or replacement.
ROSAHL products consume very little energy compared to other types of humidification. This means they will run 24 hours a day, 365 days a year, continuously extracting moisture from an enclosed area without incurring major energy costs. Because they are maintenance free, they will continue working for years without concern. This means no servicing and lower cost of ownership (TCO).
Rosahl membranes fit a wide variety of applications and environments from -20° to +50° C
