Panel mounted Indicating Desiccators
provide protection against corrosion, dampness and contamination
in electronic, electrical, telecommunications, computer equipment,
etc. These Desiccators incorporate Humidity Indicators, which
monitor saturation and indicate when reactivation or replacement
is required. They are blue when the desiccant is dry and
turn pink when the maximum amount of moisture has been absorbed.
A powerful adsorbing agent (either silica gel or molecular sieve)
reduces existing or incoming moisture to acceptable levels. The
use of molecular sieve desiccant is recommended when equipment
may be subject to immediate failure as a result of water vapor
condensation. The molecular sieve desiccant maintains an
ultra low relative humidity for extremely sensitive applications. It
is most suitable for applications where equipment or enclosures
may be subject to operation at low temperatures and water vapor
condensation must not occur.
These Desiccators are available in 10 gram, 30 gram and 50 gram
the chart below to select proper size and desiccant for the desired application.
The silica gel desiccators can be reactivated for re-use by heating
them at 248°F (120°C) for four hours in a ventilated oven. The
molecular sieve desiccators cannot be reactivated.
