A+ Corporation Humidisorb plus X-Corrode

Humidisorb plus X-Corrode packets provide moisture and corrosion control in electrical and electronic enclosures. Humidisorb is a self-regenerating desiccant that can absorb and release enormous quantities of moisture from the surrounding air without becoming saturated.

The contents of each packet will not affect or damage non-metal material and can withstand maximum temperatures of 80°C and contact with bulk liquid water without impacting their effectiveness. All packets come with self-adhesive mounting tape, which allows for easy installation into any enclosure, even if the enclosure is frequently opened.

When first placed in service, a packet of granules will rapidly absorb moisture. It is said to absorb at least 5-10 times more moisture than conventional desiccants before coming to equilibrium with the relative humidity of the surrounding air. This will usually take several weeks to occur, even in very humid environments.

During periods when the enclosure RH is drier than its long-term average, the packet releases moisture in vapour form. The moisture ‘desorption’ process cannot wet the air above its average RH level. When the enclosure humidity rises above the average level maintained by the product, the packet absorbs moisture. By absorbing moisture when the RH rises, and releasing some of the vapour phase moisture (regenerating) when the RH drops, the packet maintains a constant RH within the enclosure equal to the long-term average humidity.
