State which dew point is reported

Atlas Copco distinguishes atmospheric dew point from pressure dew point, which refers to condensation at a stated elevated pressure [1]. For pulse cleaning air, ask the air-system supplier to identify the basis of the reported value. Do not place unlike dew-point values in one comparison column without explanation.

02

Identify the point and operating condition

Record where the sample was taken, its date, available pressure and temperature information, and the production state. Keep the instrument identification with the result. Our documentation recommendation is to separate an upstream dryer report from a reading taken at the collector connection rather than treating them as the same measurement.

03

Compare against the actual equipment requirement

Obtain the air-quality requirement for the offered collector and cleaning components. Ask the supplier to explain how the available report relates to that requirement and which missing conditions must be confirmed. This guide does not assign a universal dew-point target or select a dryer for every plant.

04

Retain discrepancies for a joint review

If reports disagree, preserve their original units and pressure basis and ask the responsible suppliers to reconcile sampling and operating conditions. Record the conclusion and any approved follow-up. A low displayed temperature alone does not establish compliance with an unspecified equipment requirement.

FAQ: Can atmospheric and pressure dew points be compared directly?

Not without confirming their pressure basis and the required method of comparison.

06

FAQ: Does this replace the collector’s air specification?

No. Use the actual supplied equipment requirement and documented measurement conditions.
