Lower lifetime costs
Rosahl low-energy dehumidifiers use a solid polymer electrolyte membrane (SPE) to lower lifetime costs of dehumidifying steady state enclosures. They are suitable for enclosures from less than one litre to 4m³. Steady state enclosures are those sealed to minimise to ingress of moisture.
The drying process
Rosahl membranes use electrolysis to extract water vapour from the container by removing the hydrogen ions and passing them through the membrane to the outsides. Importantly, no liquid water is involved in the dehumidifying process. This makes it virtually maintenance-free. Go here to see how Rosahl works
The table shows typical drying curves for a 50 litre container using a range of membranes. On the other hand, a larger container will take longer to dry.
Rosahl membranes use no moving parts so the process is silent and free from noise and vibration. The smallest membranes are the size of a thumbnail. To operate they require only a 3 Volt DC supply and very little power so the average annual running costs are very low. In addition to the low running costs. Consequently, the membranes have a long operating life for lower lifetime costs giving the user lower ownership costs of ownership (TCO).
Due to their compact size and maintenance free operation. Firstly, they are ideal for reducing lower lifetime costs. Secondly they are suitable for use in remote applications, In addition, they can be used for equipment where regular servicing is difficult or impossible applications. Finally, the absence of maintenance also offers significant cost savings for the end user.
Examples of typical applications include
|Traffic control and display cabinets||External LED lighting|
|IP and CCTV cameras||FTIR spectrographs|
|Mobile telecommunications outstations||Laser and Piezo systems|
|Protecting sensitive electro-optic devices||Precision medical equipment|
|Museum displays and exhibition cabinets||Outdoor multimedia screens and displays|
Advantages of Rosahl micro-dehumidifiers
No moving parts
Rosahl dehumidifiers have no moving parts, meaning there is no noise or vibration when operating and nothing to wear our or service
Solid-state polymer electrolyte (SPE), meaning reliable operation with low average power consumption and a long service life
No liquid water
The process works at a molecular level, meaning no liquid water is involved, so no cleaning or drainage are needed
