Point Of Use Profile


Compressed Air, Nitrogen & Leak Detection

Our Compressed Air amp; Nitrogen auditing services are based on engineering and scientific principles, producing the most comprehensive and accurate data analysis in compressed air or Nitrogen management. Focusing on industrial air system supply and demand, U.S. Energy Engineers produces technical reports used for investment confirmation, cost reduction, system efficiency etc.

Compressed Air & Nitrogen Systems

We provide free initial facility surveys to evaluate areas of high impact, followed by comprehensive assessments. Our final recommendations are in the form of executive reports and large format technical drawings. We offer the following specialized services:

Point of Use Pressure Profile Determination

A multi-point pressure profile (data logged) is done to determine the system pressure profile. The pressure profile employs multi-channel data loggers installed into the system at strategic points and synchronized in real time and sampling rate alignment. Test run times include entire shifts or shorter durations at the discretion of the audit team engineer. Collection points generally include:

Supply Side

  • The discharge of the compressor room or rooms.
  • The discharge of the compressors, upstream of the dryers.

Distribution System

  • Points furthest from compressor(s).
  • Immediately upstream of critical production machinery.
  • Immediately upstream of mass flow dependent equipment.
  • Immediately upstream of points of use that have been historically identified as problem areas, or governed by low pressure alarms and shutdowns.

Production Equipment

  • Connections to cylinders having high cycle rates.
  • Connections to pressure sensitive clutches, brakes and clamping devices.

The pressure profile identifies the following elements:

  • Maximum and minimum pressure levels
  • Pressure stability bands
  • Possible velocity based flow gradients and restrictions in the distribution network
  • Transmission time from generation to points of use
  • The effects of uncontrolled demand, defined as demands that are not equipped with operating, modulating control regulation.
  • The effects of system leakage
  • The level of flow balance, between demand points to enable the specification of situational controls and subsystems.
  • The existence of individual demand points that require pressure levels that are determining the supply pressure to the entire system.
  • The effects of the speed of response by regulation and flow control on the performance of high-speed production equipment.
