Panel Mounting Humidity Adsorbers Give Assured Protection

These plastic units use powerful adsorbing agents in either silica gel or molecular sieve. They are blue when the humidity adsorber is dry and turn pink when the maximum amount of moisture has been adsorbed.

The silica gel humidity adsorbers can be reactivated for re-use by heating them at 100ºC (212ºF) for four hours in a ventilated oven. Molecular sieve adsorbers maintain an ultra-low relative humidity for extremely sensitive applications and cannot be reactivated. They are recommended for use on equipment or enclosures that may be subject to operation at low temperatures and wherever any chance of water vapour condensation must be positively eliminated to prevent possible immediate failure.
