Condition
Fault
Remedy
Pressure dewpoint too high
Compressor loading periods
repeatedly too short
Take necessary action to increase
duration of loading periods
Incorrect pressure difference
between dryer compartments
Check pressure difference which
should be within the range specified
in section
. Never
operate the dryer with a pressure
difference beyond the specified
range. Always be sure that the
connections of the U-tube are airtight
Operating pressure too low
Do not operate dryer at a pressure
less than 4 bar(e)
Rotor does not turn
Consult Atlas Copco
Rotor compartment sealing ring,
sealing sectors and rotor need
inspection
Consult Atlas Copco
Aftercooler air outlet temperature
too high
Regeneration cooler air outlet
temperature too high
On water cooled compressor, check
cooling water inlet temperature and
increase water flow. If temperature
cannot be decreased sufficiently,
consult Atlas Copco
On air-cooled compressors, clean
cooler externally. If temperature
cannot be decreased sufficiently,
consult Atlas Copco
Regeneration cooler air outlet
temperature too low
Consult Atlas Copco
Drain system malfunctioning
Inspect system and replace parts
where necessary
Dryer air inlet temperature is
higher than aftercooler air outlet
temperature
Regeneration cooler air outlet
temperature too high
On water-cooled dryers, increase
water flow through regeneration air
cooler
On air-cooled dryers, clean cooler
externally
