Using an ionic membrane from the ROSAHL line of dehumidifiers offers several benefits over traditional methods of air drying. Applications include electrical cabinets; antiquity displays and equipment storage cabinets. They were originally developed to prevent moisture damage to remote equipment such as CCTV cameras and traffic signs. They are suitable for indoor and outdoor application, but may need additional protection
They have since found innumerable indoor and outdoor application it has found a place in a variety of applications.
Low life-time cost is one of the main benefits of using the technology that uses electrolysis to remove water vapour from the air. Typically, a device for air drying an enclosure of up to 1m³ (35 cu. ft) would consume 3W of power at 3V dc. Importantly, service costs are also minimised as ROSAHL is maintenance free and requires no drainage. It is also noiseless and has a long service life.
ROSAHL solid state membranes are available with mountings, power supply, or as a membrane only. For membrane only the cabinet supplier would need to make a suitable installation. List prices for the membrane only start from under 20 Euros.
