Revolutionary humidity control

Rosahl offers a radical new approach to humidity control

Unique micro drying solution for OEM industrial and commercial applications

Designed for industrial and commercial applications, Rosahl solid-state dehumidifiers offer a new way to protect sensitive optical and electronic devices from moisture damage.

They use a unique polymer membrane to remove moisture through electrolysis.

Sometimes called ionic membrane dehumidifiers they work like an ionic pump to remove water at a molecular level when a low voltage direct current is applied to the membrane.  They require no maintenance; are silent and vibration free; have a low running cost, are very compact and have a long service life.

World’s smallest electric dehumidifier

These solid-state devices offer a long-term solution to humidity control for enclosures from below 500ml up to 2m³ (70 cu ft) and the smallest models are 75% smaller than an AA dry cell.  They can also be used for humidifying.
