Why Do You Need a Compressed Air Audit?
Compressed air systems are integral to the day-to-day running of countless businesses in numerous industries. However, like all other industrial equipment, air compressors sustain wear and tear over time, losing efficiency. But it is not just time that can take its toll on your vital tools and equipment.
As businesses grow, their compressed air needs often change. While your system might have been perfectly calibrated until a few years ago, it may no longer be running optimally if your requirements have changed. For example, you might have plugged new tools and equipment into your system without tweaking its settings and calibration for optimum efficiency.
Moreover, tiny inconsistencies in air pressure may now go unnoticed, but the extra electricity required to achieve the air pressure you desire could add up to a small fortune over the space of several months or years.
Fortunately, by hiring our experts for a compressed air audit, you can maximise the lifespan of your equipment while shaving a few zeros off your annual energy bill. You can also do your part to reduce greenhouse gas emissions, remain compliant with ever-changing regulations, improve workplace productivity, and much more. When it comes down to it, a compressed air audit will likely pay for itself in no time.
Below, we discuss the details of compressed air audits, including why you need them, what they involve, their key benefits, and how to prepare for your audit. If you need specific advice, do not hesitate to call us.
Understanding Compressed Air Audits
Compressed air is often referred to as the ‘fourth utility’, yet the efficiency of a compressed air system is easily overlooked. Producing compressed air can be costly, especially when hidden problems such as air leaks, poor air pressure levels, or inefficient air dryers go unnoticed.
A properly conducted compressed air system audit examines both the supply side (compressors and dryers) and the demand side (piping, end-use tools, and the wider system) to improve system efficiency and reliability. Using flow profiling and data logging techniques, we can monitor compressed air demand across shifts to identify wasted energy and operational costs.
Audits often reveal issues like artificial demand, where systems operate at unnecessarily high pressures due to leaks or poor design. By providing a comprehensive understanding of the system’s dynamics, an air audit may significantly reduce energy consumption, lower maintenance costs, and deliver long-term savings across your entire compressed air system.
Key Benefits of Conducting a Compressed Air Audit
A compressed air assessment can be a huge benefit to just about any business. Here are just some of the key advantages of a professional audit:
Increased Energy Efficiency
An audit can identify ways to improve the efficiency of your air compressor and find issues that may be causing your system to waste energy.
Reduced Business Downtime
Many workplaces rely on their air compressors for a wide array of daily tasks. If your compressor has an issue, you may not be able to do your job – any amount of downtime can cause serious harm to your business. Call us for an audit, and we will catch small issues before they become costly problems.
Reduced Operating Costs
Increasing your system’s efficiency can translate into significant savings on your operating costs. As mentioned above, some businesses reduce their total energy expenditure by up to 50% following an audit.
Reduced Greenhouse Gas Emissions
Keeping your systems in full working order can significantly reduce your C02 emissions, helping you do your part for the environment.
UK Standards Compliance
Trust us to carry out your audit. You can feel confident that you will always remain compliant with ever-changing quality, safety and efficiency regulations.
Why Do You Need a Compressed Air Audit
Common Issues Identified During Audits
Some of the most common issues found during a compressed air audit include:
Air Leaks
Air leaks in an air compressor can account for up to 50% of the system’s energy loss. They are often caused by poor maintenance, improperly installed connections, and general wear and tear.
Inappropriate Pressure Settings
If your air compressor’s usage has changed, you might no longer have the air pressure settings appropriately optimised, which can lead to premature wear and tear and high energy bills.
Incorrectly Sized Equipment
If you are using dryers, filters, or compressors that are not the correct size for your system’s demand, you may be spending much more than necessary on energy.
Contamination and Moisture Issues
Inadequate drying processes and poor air filtration can lead to contaminants like water, oil, and particles infiltrating the system and damaging your equipment — issues that can be uncovered through professional air quality testing.
The Audit Process – What to Expect
A compressed air system audit is a detailed assessment designed to comprehensively understand your system’s performance and efficiency.
Our audit team starts by reviewing your site layout, compressor room setup, air dryers, piping, and end-use applications. We gather key information such as system pressure, current energy use, and maintenance records to build a clear picture of your system dynamics.
We then install data logging equipment to monitor airflow rates, pressure levels, power consumption, and compressed air demand over time. This approach captures how your system operates during different shifts, ensuring a true reflection of your energy usage rather than a single snapshot.
The audit covers both the supply side (compressors, dryers, filters) and the demand side (piping, tools, end uses), allowing us to uncover hidden issues like pressure drops, artificial demand, and leaks. We also carry out air leak detection and air quality checks where needed.
After collecting and analysing the data, we deliver a detailed report highlighting key findings, areas for improvement, and potential energy savings. Our tailored recommendations aim to help you reduce energy consumption, lower operational costs, and improve the reliability of your entire compressed air system.
How to Prepare for a Compressed Air Audit
Depending on your unique situation, we will let you know exactly what we need to perform your audit as efficiently and effectively as possible. However, it will be a great help if you can provide us with documentation such as your system manuals, maintenance logs, and energy usage data. You can also help speed things up by ensuring we can easily access all your equipment, including the piping, end-use points, and compressors.
