moisture removal and temperature variation demands on the refrigerated dryer.
Between the compressed air receiver and dryer, a general purpose coalescing filter with
an automatic drain is used to remove liquid water, liquid oil and solid particles from the
airstream. Pre-filtering eases the load on the dryer and prevents an emulsion of water,
oil and particulates from forming. This emulsion can leave a deposit that reduces heat
exchanger efficiency and clogs automatic drains.
For applications that require ultra-clean air, additional filtering may be required to
remove the oil aerosols and vapors present in most systems. Oil coalescing filters
remove oil in aerosol form. To remove oil vapor from the air stream use a filter fitted
with an adsorbing activated carbon cartridge at the dryer outlet.
Note that the inlet and outlet ports of the air dryer are labeled. A dryer bypass valve
should be installed for air dryer servicing. If the aftercooler exit air temperature
averages less than 100°F, the dryer including prefilter and bypass system can be
placed between the aftercooler separator and receiver.
If not already in place, connect condensate drain tube to the dryer's moisture separator
drain trap. Position outlet of drain tube in such a manner that condensate will be
drained away from dryer and other mechanical or electric equipment.
Make sure when piping is in place that no undue stress is placed on dryer connections.
Union joints or flexible connections are recommended to relieve stress.
Dryer is to be connected to an appropriate electrical power source based upon
specifications shown on unit data label. Do not connect unit to a power source other
than that called out on data label. Power source should incorporate a fused disconnect
using a fuse, not exceeding the maximum fuse size stated on the dryer data label.
Piping:
A. Piping installation should follow general air line piping procedures.
B. A bypass valve system is recommended in the dryer's pipe connections. This
permits servicing of the dryer without the interruption of the airflow.
C. If the pipes connecting the dryer vibrate, such as from compressor vibration, use
vibration absorbers so that the dryer is not damaged over time by the vibration.
D. The inlet and outlet ports on the dryer are labeled.
E. Direct the drain tube under the dryer to a suitable sump. Do not restrict the drain.
Filtration:
A. A compressed air filter with automatic drain should be installed upstream of the
dryer. Filtration of dirt, rust and liquids from the supply air will greatly enhance the
performance and life of the dryer. Your distributor can provide additional information on
compressed air filters.
