DEHY 1 DAILY CHECK LIST DOUBLE DUTCH
This daily checklist verifies safe, efficient operation of the DEHY 1 unit by confirming run status and documenting oil level/temperature/differential pressure, separator DP, leaks/vibration, fan condition, drains, instrument gas pressure (>85 psig), valve alignment, and containment closures, with photo evidence where prompted. Technicians record PASS/FLAG/FAIL results to trigger timely corrective actions and maintain reliable dehydration performance.

Is Dehy running?
take picture of oil level and check for leaks and valve alignment
Dehy Oil Level
Add or drag pictures
Dehy Oil Level
Check Both Scavenger Site Glass (Only the one from the top of vessel should have oil present)
Check Oil Differential Pressure
1-25psi change filters at 20psi
Check Oil Temperature Delta T
Entering temperature compared to exit temperature of oil
Check DP on oil gas separator @ Gauge (if DP >6, replace)
Check Compressor for Oil Leaks, Vibration and Hub Damage
Check Water Knockout and Drain if Needed.
Check Air Cooler Fan for noise, debris and vibration.
Check DrainAll Pneumatic Pump to ensure it is operating correctly.
Instrument Gas Pressure (SP >85psig)
Instrument Gas Pressure (SP >85psig)
Add or drag pictures
Are Oil Containment Valve/Plugs closed?
Check Valving alignment on piping
