Enclosure dehumidifier for industrial and commercial use

Designed for industrial and commercial applications, Rosahl micro-dehumidifiers use a solid polymer membrane to remove moisture from sealed enclosures when a low voltage is applied. The products cover volumes from one litre to 4m³.   A small cut-out is made in...

Small volume, low power enclosure dehumidifier

Rosahl is a unique, low power electric micro-dehumidifier for enclosures from under one litre up to 4m³. It uses a polymer membrane electrolyte, driven from a 3V DC power source. This is usually supplied from a transformer, but when correctly applied, it can be...

Protecting photonic devices from moisture damage

Protecting photonic devices from moisture damage Removing moisture from small enclosures is a problem for engineers. The water vapour present can affect the performance the equipment in various ways. For example, it may affect the outcome the process. Alternatively,...

Cabinet humidity control and stabilisation methods

Cabinet humidity levels can be controlled within tolerance using the ROSAHL solid-state ionic membrane dehumidifiers. This is achieved by having either one or two membranes: one to humidify and one to dehumidify. They are used for accurate cabinet humidity control...

Protect remote equipment from humidity and condensation

Protecting remote equipment from humidity and condensation damage Rosahl is a maintenance-free electric dehumidifier designed for use in electrical cabinets with volumes one litre and larger. It is frequently used for protecting remote equipment from humidity and...

Temperature change key to cabinet humidity control

Temperature change is key to cabinet humidity control   Large temperature changes have a significant impact on relative humidity levels, and this is particularly significant when considering enclosure dehumidification. It is difficult to keep a fixed relative...
