What is the IP rating of Rosahl dehumidifier membranes?

Is Rosahl waterproof? Rosahl dehumidifiers work by passing gasses through the polymer membrane to the outside of an enclosure. To achieve this, they must be porous to gas and vapour. However, they are not porous to solid particles or liquids under normal conditions....

Working with dehumidifier drying time curves

Micro-dehumidifiers are used to air-dry small enclosures and cabinets up to 4m³. For ease of use, dehumidifier drying time curves are shown in graphical form, based on defined conditions.   However, there are many factors that can affect the drying times, and hence...

What is an electrolytic dehumidifier?

Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them. Rosahl dehumidifiers are mounted over a cut-out in the side of the enclosure, and use a small electrolytic...

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 the...

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,...
