Medium Flow Compressed Air Dryers - IOMI.
Warning
Troubleshooting should only be attempted by competent personnel. All major repair and calibration work should be
undertaken by a Parker trained, qualified and approved engineer.
In the unlikely event that a problem occurs on the equipment, this troubleshooting guide can be used to identify the probable cause and
remedy.
PROBABLE CAUSE REMEDY
The inlet parameters have changed.
If the inlet flow-rate or the inlet temperature have increased ensure that the
filters and dryer are re-sized accordingly.
If the inlet pressure has changed ensure that the filters and dryer are re-sized
accordingly.
The condensate is not being drained.
Verify that all condensate drains are functioning correctly.
Check that the drain hoses are free from kinks and obstructions.
Ensure that the isolation valves on the drains are fully open.
The compressor is not functioning correctly.
Check the documentation supplied by the compressor manufacturer for
troubleshooting guidance.
The compressor capacity has changed.
Ensure that the filters and dryer are sized accordingly.
The after cooler is not functioning correctly.
Test that condensate drain is operating correctly.
Check that the cooling water system is functioning correctly and that the
water temperature is within specification (water cooled systems only).
Ensure that the after cooler and dust filter (if fitted) are clean (air cooled
systems only).
Ensure that the fan is functioning correctly (air cooled systems only).
There is no wet air receiver fitted within the system.
Install a wet air receiver and drain within the system (if possible).
Ensure there is adequate drainage on the piping prior to the dryer pre-filtration.
A water separator should also be installed before the dryer pre-filtration to ensure
removal of bulk liquid.
Filtration has not been correctly maintained.
If the element and float drain have been installed longer than 12 months
ensure that they are both changed.
Verify that the float drain is operating correctly.
The dryer has been by-passed.
If a bypass line has been installed on the system ensure that it is closed. Use
bypass filtration.
The regeneration column pressure within the dryer is greater
than 350mbar.
Contact a Parker approved service agent.
There is a fault with the dryer timer. Contact a Parker approved service agent.
There is a fault with the dryer valves.
Contact a Parker approved service agent.
The desiccant is approaching the end of its useful life. Contact a Parker approved service agent.
Dewpoint Failure
A dewpoint failure will result in there being water in the downstream piping and equipment
