Leak Surveys: how to save energy – and money


If someone told you that they could save your company thousands of pounds a year, you would want to know more. So why do so many businesses do so little about air leaks?

You may consider air leaks a minor problem but they can represent a major cost. While leakage can never be completely eradicated, it’s not unusual for a compressed air system to be losing 30% to 60% of its air through as many as 70 to 100 leaks. To put this in perspective, the acceptable level of leakage is 10%.

Leak surveys and energy audits can help fix the problem – and at Simm we offer this service for free.

How does fixing leaks save you money?

There are three ways that you can save money in the long run by fixing leaks:

  1. Your energy bills will go down if you don’t need to generate as much compressed air
  1. Compressors and other machinery have to work harder if air is being lost through leakage, but increasing the pressure shortens the life of the machine, causes parts to wear out more quickly and risks machinery failure, leading to factory downtime
  1. You may be thinking of buying a new compressor to compensate for a shortfall in compressed air supply – this capital expenditure can often be saved

Leak location

Leaks are not only found in pipework but also in connections to machinery, in particular joints, valves and seals, as well as filters and solenoids. Air and other tools may also be leaking air.

Engineer at the ready

With free leak surveys on offer, it really is a no brainer. Our engineers will call at a time to suit you and will carry out the leak survey without disrupting your production schedule.

Leak locations and flow rates are measured using an ultrasonic acoustic detector, then tagged. The engineer will then write up a report for you, detailing the level of leaks and an estimate of costs – including how much you might be able to save on your energy bills, moving forwards.

Whether there’s a quick fix, such as tightening a component or mending a seal, or whether new parts are required, our engineers will be able to recommend the best and most cost-effective solution.

Once the leaks are fixed, you will be able to lower your system pressure and you will start to see an increase in energy efficiency – leading to lower bills.

There are also environmental benefits, as fixing leaks will decrease your company’s carbon footprint.

Maintenance and monitoring

The service doesn’t stop there, however, as the best way to keep your system working at optimum levels is to keep monitoring it over time. This will ensure that any new leakages are dealt with as they occur.

Regular servicing is recommended for all compressed air systems as it will save you money in the long run by identifying potential problems before they cause system failure and costly downtime.

In short

Dealing with leaks is often an afterthought as they aren’t visible in the way that problems such as faulty machinery might be.

However, when it comes to energy and cost savings, leak surveys are one of the best options you can choose.
