Heatless Desiccant Dryers

Instruction Manual
Technical notes
1.
Pre-filtration, including a Water Separator is essential to maintain dryer performance.
2.
An appropriate Water Separator must be installed. If bulk water enters the adsorption dryer it can cause heat expansion to the
desiccant, substantial rise in the dryer differential pressure, poor outlet dewpoint, potentially resulting in dryer failure.
3.
The manufacturer recommends fitting a reverse flow
0.01 micron dust filter
to the outlet.
4.
Call your nearest manufacturer sales team for further information.
