operate continuously to assure a constant supply of dried air on demand.
The 3-way control valve controls the flow of dried air into the chamber
workspace.
The air pump, dryer and valve are mounted inside the control section of
the Chamber. The air intake to the pump is muffled and is very quiet.
The pump draws in ambient air and compresses it to 50 psi. The
compressed air is passed on to the dual column dryer where it is forced
through one of the desiccant columns. The desiccant removes the
moisture and dries the air down to a dew point of -40 °F, minimum.
The dried air is then split in two directions: Most of the dried air is sent to
the output. A small portion of the dried air is diverted from the main flow
and directed into the second column to regenerate the desiccant in the
second column. The flow into the second column is in the opposite
direction from the flow in the first column. The dried air, under high
pressure, forces out any moisture in the second column through the
dryer vent (located internally).
Every 30 seconds, the process reverses and the second column will
perform the air drying while the first column is regenerating. The flip-flop
process continues as long as the system is in use.
The dried air not used for regeneration is sent to the dryer output. The
output of the dryer is attached to the 3-way control valve. When dry air
is needed in the chamber, the valve is energized and opens to allow dry
air to flow into the workspace. When the valve is not energized, the dry
air is vented.
2.2.2.2 Unit Specifications
1. The average flow rate from the unit is 0.26 cfm (7.3 lpm).
2. The air will be dried to a minimum dew point of -40°F with a
saturated input at 90°F.
