Larger sizes of Rosahl micro-dehumidifier membranes are availabe with either moulded plastic surrounds as in the MDL types, or mounted on pre-drilled stainless steel plates as in the M-Series
New Rosahl mounting kits
The new range of optional Rosahl mounting kits for the MDL series of membranes is designed to simplify membrane installation. Fabricated from pre-drilled stainless steel, three models are available: for the MDL-3, MDL-5, and the MDL-7. They can be purchased as kits, comprising a retaining plate and two packers/gaskets. The packers are manufactured from ethylene propylene gaskets and are also available seperately.
It is recommendd that gaskets are fitted to both sides of the membrane to reduce moisture ingress and ensure a reliable installation. The retainer plates should be fixed using M4 screws, with care taken to ensure the membrane terminals are adequately distanced or insulated from the panel surface.
When installing in an outdoor panel fitted with a rain cover, care should be taken to avoid interference with the rain cover attaching screws.
Advantages of Rosahl micro-dehumidifiers
Silent & vibration free
Rosahl dehumidifiers have no moving parts so there is no noise or vibration when operating.
Long Operating Life
Rosahl uses a solid-state ionic membrane giving it a long service life and low operating costs
Low Energy Footprint
Rosahl membranes operate at 3V d.c. and use a very low average operating current to save energy
No moving parts
Rosahl dehumidifiers have no moving parts so there is no noise or vibration when operating and nothing to wear our or service
Solid-state polymer electrolyte (SPE) provides reliable operation with low average power consumption and a long service life
No liquid water
The process works at a molecular level and no liquid water is involved, so no cleaning or drainage are needed
