Rosahl solid state micro dehumidifiers/humidifiers for small enclosures

[axxess]

Has any one used them, also would they work with a wine chiller for curing and storing ROSAHL is a unique dehumidifier that utilises a solid state polymer ionic membrane (SPE) to electrolytically decompose and remove moisture from the air by electrolysis when a 3V dc voltage is applied. They provide clean moisture extraction and low cost, maintenance free, and silent performance. When a voltage is applied to the porous electrode attached to the SPE the moisture on the anode side (dehumidifying side) dissociates into hydrogen ions (H+) and oxygen: the hydrogen ions migrate through the membrane to be discharged on the cathode (moisture discharging) side where they react with oxygen in the air, resulting in water vapour being discharged. Similarly, if the membrane is reversed a humidifying effect is achieved. http://www.rosahl.co.uk/how-does-rosahl-work-2/

These look interesting. Have you priced them yet?

 

[SweetDee]

I wanna play with em!

 

[Devilman]

Nice idea, but the prices look too high at the moment to be viable, £225 for somethin like 58ml of water a day. Be interesting to see what they can do in a few years though I reckon

Rosahl pricing

Pricing for Rosahl membranes is based on the quantity ordered. Prices are given below for some of the more popular models. Prices are in GBP (UK Pounds), but if you require prices in US Dollars, Euros, or have particular quantity requirements please contact us.

The key to evaluating Rosahl is to include lifetime cost of ownership offered by its maintenance free performance, low running costs, and the levels of humidity control offered. Special materials are used in the production of the ionic membrane at the heart of Rosahl, and which provide its unique characteristics.
