WEEKLY:
1.
Check differential pressure across prefilter & afterfilter
elements. Replace if required.
2.
Check and maintain operating conditions; Pressure,
flow, and Temperature within the design parameters of
the dryer.
SEMI-ANNUALLY:
1.
Inspect desiccant for physical condition. Desiccant
from a freshly regenerated bed should be white, dry to
the touch and of consistent size & shape. If desiccant
condition is in question, send a sample to AIRTEK for
analysis.
2.
Check and clean mufflers. This may be required often
under certain conditions or if back pressure develops.
Mufflers may require replacement if severely clogged,
or after a few cleanings.
3.
Replace prefilter and after filter elements
4.
Clean automatic drain.
5.
Replace purge filter element (TW25-55).
6.
Check and Blowdown Safety Valves. Refer to
manufacturer's instructions.
7.
Clean dryer.
ANNUALLY:
1.
Inspect and rebuild inlet and Exhaust Valves.
2.
Return PowerLoc probe & chip for recall, if applicable.
Note: No lubrication is required.
11. A. GENERAL PARTS DESCRIPTION:
A.
Desiccant – An adsorbent used for drying air or gases.
Proper quantity, size and type necessary.
B.
Inlet Switching Valves – 4-way electric switching valve.
Directs inlet air to drying tower and purge air from regener-
ating tower to exhaust.
C. Exhaust Valve – Normally Closed solenoid valve used
to exhaust purge air, hold air in tower on line, and exhaust
air from tower ready to be regenerate.
D. Outlet & Purge (TW25-55) Check Valves – Valves that
allow full flow in one direction and no flow in the other are
used in conjunction with the inlet and exhaust valve to
accomplish desired flow of process and purge air.
E.
Safety Relief Valves – Furnished on each tower to
protect the vessels from over pressure situations. Standard
setting is 150 PSIG.
F.
Purge Exhaust Muffler – Furnished to reduce exhaust
noise during purge and blow down for personnel protection
and to comply with OSHA standards. Mufflers offer no
benefit to the operation of the dryer and are a maintenance
concern.

Consideration should be given to locating the exhaust in an
area where mufflers would not be required.
G. Purge Control Valve – Furnished to adjust & regulate
purge flow for regeneration.
H. Solid State Controller/Sequence Annunciator –
Furnished for cycle control. Outputs operate 2 electric
solenoid valves. Provides for variable cycle control.
Provides interface for CycleLoc control or optional
PowerLoc Demand Control. Has integral lights to provide
visual cycle indication. Has built-in autodrain control. All
hard wired connections including field power connection,
made to this board.
I.
Tower Pressure Gauges – Furnished to read pressure
in each tower. On-line tower should read line pressure,
regenerating tower should read 0 psig.
J.
Purge Flow Indicator (center gauge or flow meter
TW25-55) – Furnished to indicate and monitor proper purge
flow.
K.
Purge Air Filter – Filters purge air, which is taken from
the dryer outlet, to protect the purge orifice and needle valve
from desiccant dust. Also protects PowerLoc probe where
applicable.
