Compressed air is a very versatile tool used in a broad range of industries to power machinery, valves and actuators and hand tools. Compressed air generation accounts for 10% of all energy consumed in UK. The Carbon Trust has reported that the UK uses over 10TWh of electricity annually to compress air which is the equivalent of about 1.5 power stations emitting 5 million tonnes of CO₂ to the atmosphere or powering 120 million 60w (equivalent) LED lightbulbs for a year.
However the process of compressing air can be very wasteful. As little as 8% of the total energy supplied to a compressor is actually converted into useful energy at the point of use.
Effective minimisation of waste can save over 30% of the energy required. Small leaks in a compressed air system can waste huge amounts of energy; a leak as small as 3mm could cost more than £700 a year in wasted energy.
Conducting a compressed air system audit is vital as it is the easiest and most thorough method to ensure that your compressed air system is performing to its upmost efficiency. There are several legal requirements when using compressed air such as having the system regularly checked by a competent engineer.
Using a reliable compressed air maintenance team who will come to your plant and examine your compressed air system can be really beneficial. The compressor engineer will produce a checklist of suggested improvements to your compressed air system. The most common issues that a compressed air system audit will flag up are leaks, unfit piping, inefficient compressors and the need for an air compressor controller.
A compressed air system audit generally more than pays for itself in the energy savings made within a relatively short time. However optimising individual components in a compressed air system does not necessarily result in optimisation of the entire system. For a more effective result it is better to take a systematic approach by analysing each component of the compressed air system.
A compressed air system audit looks to maximise uptime and reduce total operating costs. The audit will measure the actual compressed air demand at various times to produce an Air Demand Analysis (ADA).
The world famous air compressor brand HPC KAESER has a specialised energy saving system software which makes specific recommendations regarding the most suitable machine configuration. An average audit saves around 30% of energy use and often much more.
Once the information has been collected and analysed the audit will produce a personalised action plan with the best solution for the minimisation of energy consumption and maximising uptime for the recommended machine configuration.
