Improve your CO2 footprint

Published:  11 August, 2009

Alastair Shanks, managing director of Airchannel, independent compressed air and pneumatics specialist, believes that companies can find not only cost savings but ways of reducing their CO2 footprint by carrying out a compressed air energy efficiency and leak audit.

The first stage of an energy audit is a complete review of the compressed air system in order to identify inefficiencies and potential energy saving measures that could be taken.

This involves using calibrated non-disruptive equipment that logs a system's data via an industrial PC with sophisticated analysis software. The raw data is then configured against the measured power and output performance for each compressor and the site energy cost over a 24-hour cycle. Using the audit, the existing system performance can be established, identifying opportunities where efficiency can be significantly improved and cost reduced.

The next stage is to check for leaks, which cost money every minute of every day that a compressed air system is running. With ultrasonic leak detection equipment, leaks can be detected and identified as small, medium or large.

When the two audits are combined, not only are there potentially cost savings but also environmental benefits in relation to reduced CO2 emissions as less energy is used. It"s a win-win situation.
