What to do if Ingersoll-Rand Dryer has elevated dew point?
- F
  fflowersAug 14, 2025
  If your Ingersoll-Rand Dryer has an elevated dew point, several factors could be the cause. First, check the purge flow settings to ensure they are sufficient. Also, inspect the purge piping for any obstructions and clean the purge piping and muffler. Verify that the inlet air pressure meets the design conditions and check the system for leaks. Ensure the flow rate is within the design specifications and address any increased demand. If the inlet temperature exceeds the design condition (120°F), inspect and service the aftercooler. Also, check the air/moisture separator and pre-filter for entrained water and replace the dryer desiccant if needed. Finally, if the desiccant is contaminated by oil, install a suitable pre-filter and replace the dryer desiccant.

Why Ingersoll-Rand Dryer fails to shift?
- A
  Ashley CollinsAug 18, 2025
  If your Ingersoll-Rand Dryer fails to shift, it could be due to several reasons. First, check the power input to ensure there is power. Next, inspect the no-loss drain valve for any defects. Also, check the pilot air line and ensure that the control air line filter is clean. Finally, examine the pilot-operated diaphragm valve seals and replace them if necessary.

What to do if Ingersoll-Rand Dryer has excessive pressure drop?
- P
  Patrick StewartAug 21, 2025
  If your Ingersoll-Rand Dryer experiences an excessive pressure drop, it could be due to excessive flowrate, so check the flow rate and cause for increased air demand. It could also be caused by the inlet pressure being below the design condition, in which case you should check the pressure source.

What to do if my Ingersoll-Rand Dryer fails to pressurize?
- T
  Timothy HumphreyAug 25, 2025
  If your Ingersoll-Rand Dryer fails to pressurize, check that the repressurization circuit is sending a control signal to the purge valve. Also, inspect the purge valve and its no-loss drain valve.

What to do if Ingersoll-Rand Dryer depressurizes too rapidly?
- J
  james23Aug 28, 2025
  If your Ingersoll-Rand Dryer depressurizes too rapidly, it may be because the purge valve does not close, causing the dryer to repressurize through the inlet valve. Check the purge valve and its no-loss drain valve.

What to do if the Blue Moisture Indicator (BMI) indicates high moisture level in Ingersoll-Rand Dryer?
- M
  Mallory AtkinsonAug 31, 2025
  If the Blue Moisture Indicator (BMI) in your Ingersoll-Rand Dryer indicates a high moisture level, it could be due to an elevated dew point. Refer to the corrective actions for 'Elevated Dew Point'. Also, if the BMI is wet, it may take a week or more of continuous use for it to switch back to its blue (dry) state, depending on the degree of saturation of the desiccant.

How to fix Ingersoll-Rand Dryer that fails to purge?
- M
  Morgan CarrSep 4, 2025
  If your Ingersoll-Rand Dryer fails to purge, it may be because the purge valve does not open or is stuck in the closed position. Check the purge valve and its no-loss drain valve, and repair or replace them if necessary. Also, check that the repressurization circuit is sending a control signal.

What causes excessive back pressure in regenerating tower of Ingersoll-Rand Dryer?
- R
  Raymond HernandezSep 7, 2025
  Excessive back pressure in the regenerating tower of your Ingersoll-Rand Dryer (above 5 psig) could be due to a dirty purge muffler that does not pass air; replace it. It may also be caused by the purge muffler passing too much air because air is leaking across the valve; check the inlet valve and outlet check valves, and verify the inlet valve is closed to the purging tower (0 psig tower).

What causes excessively high pressure at the purge gauge on the right tower of Ingersoll-Rand Dryer?
- S
  Samantha TaylorSep 12, 2025
  If there is excessively high pressure at the purge gauge on the right tower of your Ingersoll-Rand Dryer, it could be due to improper calibration. Reset it when the right tower is online.
