MDL 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. They are MDL-3KIT, MDL-5KIT, and the MDL-7KIT.  Each kit includes a retaining plate and two packers/gaskets.

The packers are manufactured from ethylene propylene gaskets and are also available separately. If packers are supplied locally, they should be made from ethylene propylene rubber, PTFE with a hardness of approximately 50, or similar material.

Installation

As shown in the figure, fit the packing to both sides of the dehumidifying element, attach the retainer plate on the top and fasten at around four points around the edge with M4 screws. Care should be taken to ensure the membrane terminals are adequately distanced or insulated from the panel surface.

Optional parts

 

Rain cover for direct installation

Where the membranes are installed outdoors, protection against the elements is necessary to prevent rain drops and insects from entering the moisture discharging outlet. Installers may wish to develop their own solution, or rain covers and adaptor sets are available from Westside International. The rain cover is generally used where the membrane is installed directly onto the side wall of he cabinet or enclosure. When installing in an outdoor panel, avoid interference between the mounting screws and the rain cover.

 

 Adapter set for indirect installation

The adapter set is designed for retrofit installations where making square holes in existing cabinets is difficult. The product is suitable for round moisture discharging holes and prevents raindrops or insects from entering the holes when a dehumidifier is used in an existing outdoor panel. A special vent cover is included.
