Benefits of Rosahl dehumidifiers
Equipment failure due to moisture has major cost implications for OEMS, machine builders and end-users, but is simple to avoid.
Rosahl solid-state electric dehumidifiers also protect sensitive electronic and optical equipment from long-term moisture damage.
From by a leading global manufacturer, Rosahl uses a compact solid polymer electrolyte (SPE) membrane for long-term maintenance-free drying.

VREG2 Power adapters
VREG2 are compact power adapter boards designed to convert a standard USB power source to a stable 3V DC output, suitable for use with Rosahl membranes.
Each board features an onboard USB-C connector and provides the constant current-limited output recommended by the membrane manufacturer for reliable operation.
VREG2 adapters are compatible with all PD, RD, and RS small dehumidifiers, as well as the M-IJ, M-2J, M-3M, M-3J Series, and MDL-3 membranes.
More informationMembrane Dehumidifier Mounting Kits
Rosahl membrane dehumidifiers are usually installed inside the enclosure or cabinet they’re protecting. But for smaller enclosures, mounting the dehumidifier externally can sometimes work better—giving you more space inside and easier access.
To make installation simple, we offer a range of mounting kits for both internal and external setups. These kits help position the membrane correctly so it can effectively remove moisture, no matter where it’s mounted. Three kits styles are available for internal and external mounting of different membranes.
