Prevent moisture damage to electronics.

 

Unlike silica gel and other desiccants, Rosahl micro-dehumidifiers offer a new way to protect electronics from moisture damage.  Starting from the size of a one Euro coin, these membrane dehumidifiers operate continuously and without the need for regularly replacement or recharging in order to retain their moisture absorbing capacity. Considering the damage and replacement costs to electro-optics and electonic devices, membrane dehumidifiers offer considerable savings.

Noiseless and vibration free

Membrane dehumidifiers use a solid polymer electrolyte (SPE) that removes water vapour by electrolysis when a 3VDC charge is applied to the terminals.  SPEs are designed for use in small sealed enclosures from one litre to 4cubic metres, depending on the model. They are economical to operate, have a long operating life, and have no moving parts to are noiseless and vibration free.

Maintenance-free

One of the advantages of electrolysis is that the dehumidification process does not involve liquid water, making the process maintenance free. No drainage system means no emptying, no cleaning, no pipes and no mould, improving both reliability and cost of ownership the cost.

Low energy dehumidifier

Low energy consumption is another important consideration.  The compact size of membrane dehumidifiers ensures that they have low power consumption and the annual average power consumption of the largest membrane is about 10 Watts.

Membrane micro-dehumidifiers are best used in cabinets and enclosures to prevent moisture damage, and where the enclosure is sealed against further moisture ingress.  Typical applications for membrane micro dehumidifiers include:

  • Traffic control and display cabinets
  • Outdoor multimedia screens and displays
  • LED and laser lighting systems
  • Mobile telecommunications outstations
  • Precision equipment storage cabinets
  • Museum displays and exhibition cabinets
  • Protecting sensitive eleco-optics devices
  • Storage of hygroscopic materials
  • Semiconductor manufacturing
  • FTIR spectrometers
