Rosahl low temperature dehumidifier operates below freezing

  The Rosahl membrane dehumidifier is designed to work below freezing and effectively throughout its operating temperature range of below -20C to +50C (-4 to 122F). Operating below freezing is unusual for an electrical dehumidifier, but Rosahl membrane dehumidifiers are not affected by the freezing point of water as they operate at the molecular level. Rosahl works like an ionic pump and is often referred to as an ionic membrane dehumidifier.  When a low voltage (3V D.C.) is applied to the membrane, the moisture on the inside of the...

Solid-state micro dehumidifiers at Photonex 2013, the UK’s premier photonics fair

  Rosahl solid-state micro dehumidifiers will be exhibited in the UK for the first time at the Photonex 2013 Exhibition and Conference in Coventry at the Ricoh Arena on 16 and 17 October 2013. Rosahl was developed in response to a demand for compact, maintenance free, air drying solutions to protect sensitive devices from moisture damage. Designed for industrial and commercial applications, Rosahl offers a new way to protect sensitive optical and electronic devices from moisture. Rosahl is silent, vibration-free, maintenance-free, long...

How do ionic membrane dehumidifiers compare?

High levels of water vapor or moisture can lead to extensive damage of natural materials, electronics, optics and many other equipment and products so how do ionic membrane dehumidifiers compare with the alternatives? If you think about it, removing water vapor is a lifetime’s work and the solution need to be efficient and cost effective. The two most popular methods of removing moisture from enclosures and small spaces are absorption and condensation.   Other popular methods include heat rods and air purging: all have advantages and...

Rosahl ionic membrane dehumidifier on YouTube

    Designed for industrial and commercial users, the Rosahl ionic membrane dehumidifier offers a revolutionary way to protect sensitive optical and electronic devices from moisture damage, and now you can watch air dry on our two minute video on YouTube. Rosahl uses an electrolytic membrane to remove moisture at a molecular level when a 3 volt dc supply is connected.  The moisture is expelled as a gas: water is not produced and there is no need for cleaning or draining.  The membrane will also last for up to eight years before it...
