The studies involve computing the flow (by pump up test of suction velocity measurement), measuring
pressure as well as motor input power to assess operating performance of the individual equipment.
The typical scope of the work covers
Measuring the compressor output (Free Air Delivery – FAD) by conducting Pump-up Test, if possible
Measuring the air velocity at the compressor suction
Noting down cross-sectional area of the suction
Computing output through suction velocity measurement method
Determining Power with clamp on or plug in type power meter
Gauging pressure drop across the suction duct, if possible
Gauging pressure drop across the suction filter, if possible
Noting down pressure at inlet and outlet of each stage of the compressor
Noting down temperature at inlet and outlet of each stage of the compressor
Determining Specific Power
Comparing the values with the design data to analyzing the gaps, if any.
Evaluating performance and energy consumption of Air Dryers
Estimating pressure drop in the interconnecting piping and equipment’s till compressor house outlet
Assessing the performance and suggesting ways for improvement, as applicable
Submitting the report
A team of two engineers is deputed to carry out the studies and furnishing the report. The field visit is
typically for 5 to 6 hours; during which up to 10 measurements can be carried out depending upon initial
preparations,conditions of ducting systems and support from the plant team.
