Rosahl membranes offer maintenance free dehumidification

    Rosahl technology uses a unique low voltage membrane to electrolytically remove moisture from enclosures.   Because no liquid water is involved at any time,  they are compact, maintenance-free, long lasting and inexpensive to run.  This makes Rosahl particularly suitable for sites requiring maintenance free dehumidification, where access is difficult, in complex equipment and for use in remote locations. Rosahl was developed in response to demand for compact maintenance free, air drying solutions to protect sensitive equipment from moisture damage.  It has since found its way...

Stop lens fogging in HD CCTV systems

No matter how good the CCTV system, lens fogging due to humidity makes the images and the investment useless.  A version of the Rosahl micro dehumidifier has been developed specifically for the new generations of compact high performance CCTV systems Designed for HD CCTV cameras New generations of high definition day/night CCTV cameras offer a step change in performance from models previously available.  They enable operators to zoom in and  clearly identify faces, number pates and suspicious activities. Rosahl micro dehumidifiers use a solid state ionic membrane that is long lasting and...

Drying without draining

Most methods of dehumidifying require regular maintenance. Rosahl is different. If you’re in business, lifetime maintenance costs are often more than the cost of the equipment, but if  maintenance intervals are missed then the consequences can be even worse. Rosahl is a small membrane that removes moisture through electrolysis. It needs no maintenance, has a low running cost, is very small and has a long service life. Traditional drying cabinets often use thermal cooling systems designed to condense unwanted moisture and then drain it away.  Cooling is produced by thermo- electric...

Protecting electronics from moisture damage

In an article on contamination and moisture effects on printed circuit board reliability, ERA Technology* identified moisture; applied voltage, and ionic contamination as leading causes of failure.             To remove moisture from even the smallest of enclosures and prevent condensation, a dehumidifier 25% the size of an AA battery has been introduced by Japanese technology company Ryosai Technica Company.  Using a unique solid state polymer electrolytic (SPE) membrane the ‘ionic pump’ uses electrolysis to remove moisture from inside an enclosure...

Dehumidifier for very small applications

At a quarter the size of a standard AA battery, the latest PD3 micro dehumidifier from Rosahl is designed for very small spaces and is easily installed in a fine pitchM12 screw-in mounting (M12 P0.5). ROSAHL is a unique solid state dehumidifier. By applying a low voltage DC supply to its solid polymer electrolyte (SPE) moisture disassociates into hydrogen ions and oxygen and is expelled to the outside of the enclosure. It makes no noise, doesn’t wear out, requires no maintenance, is very small and cheap to run. PD3 is the smallest in a line of dehumidifiers suitable for enclosures up to...
