The ROSAHL solid state dehumidifier uses an advanced polymer membrane to remove moisture from industrial and commercial enclosures. Originally designed to protect sensitive electrical and electronic equipment in remote or difficult to service outdoor locations, the membranes are economical to run, maintenance free, and have a long service life. They are also silent in operation, making them suitable for museum displays and other indoor applications.
The smallest in the family of membranes measures 24 x 30 x 5.5mm and is suitable for enclosures up to 0.2 m³ (7 cu. ft.). It has a very small electrical footprint, using an average current of 80mW from a 3V d.c. supply making it ideal for situations requiring a constant environment. Larger sizes are available for enclosures up to 8m³ (280 cu. ft)
With no moving parts, no drainage pipes to clean and a long maintenance-free service operation, the low lifetime operating costs make ROSAHL an interesting alternative to conventional air drying solutions.
