| Compressed Air Dryer |
 |
The Compressed Air Dryer employs PSA (Pressure Swing Adsorption)
technology for the removal of water from compressed air in the ordinary
from. A typical Air Dryer capable of flows around three scfm works like
this. A four way valve is used to direct the wet air into first of the
two desiccant chambers. Here all of the water vapor gets removed.
Consequently the ultra dry air leaving off the desiccant chamber is
directed to pass through the outlet shuttle valve into the application.
A precision orifice located in the outlet shuttle valve disk makes a
part of the ultra dry air to be redirected back via the off-line
desiccant chamber. It also purges of the accumulated moisture. Finally
the purge air goes out from the the unit back through the muffler and
4-way valve. The process is governed by a solid-state timer which
controls the 4-way valve.
Applications
of Compressed Air Dryers:
The Compressed Air Dryers employing profitably the PSA technology has
wide commecial applications. They are the following:
- Dry Boxes
- Purge Electrical Boxes
- Pneumatic Instrumentation
- Replace Bottle Nitrogen
- Lasers
- CEMS
- Air Bearings
- Thermal Test Equipment
