How to Reduce Your Air Compressor Costs: 7 Simple Tips
Many industrial processes require air compressors, but they typically consume about 10% of the energy used in developed countries, such as the UK, the United States, European Union, China, and other countries. Despite it’s many benefits, the associated costs can add up quickly. Therefore, it is essential to consider how businesses can preserve energy and efficiently use resources.
We will explore 7 ways businesses can take to reduce air compressor costs without sacrificing quality or performance. Read on to learn more!
1. Reduce Pressure Whenever Possible
One of the most important things you can do to lower compressed air costs is to frequently evaluate your system requirements to ensure you only use the required air pressure.
For example, if your equipment requires just 7 bar of pressure to operate, but your compressed air system generates 10 bar, you are wasting 3 bar. That might not seem like a lot, but the result adds up quickly.
For every bar that you lower the pressure of your compressed air system, your energy consumption will go down by about 7%.
2. Eliminate Air Leakages
A leaking air compressor does no good for business. Up to 30% of energy can be lost due to air leaks in a compressed air system. Quite literally, this is money vanishing into thin air.
A top priority should be to regularly check your system for air leaks, and fix them as soon as possible. There are different ways to detect and mitigate air leakage problems. One way is to use high-tech scanners, and another is to use methods that don’t require much technology.
A simple trick is to apply soapy water to areas where you suspect leaks. If there is a leak, you will see the formation of bubbles. This is obviously a simple but old test, and instead we’d suggest you get in contact with us at Anglian Compressors, so we can use ultrasonic detectors.
3. Optimize Ambient Temperature
To get the most out of your equipment and reduce compressed air system costs, you need a compressor room with the right conditions. Every reduction of 5°C can result in a 1.5% reduction in energy bills.
Keeping the air in the room free from dust and moisture will ensure that the compressed air is not contaminated, which can help you save energy by reducing the need for aftercoolers, dryers, and filters.
With some investment, you can turn all the heat air compression generates into something useful (see point 6). You can also reduce your energy bill further by getting your intake air from outside when possible – especially in cooler environments.
4. Perform Regular Maintenance
Regular maintenance of compressed air systems isn’t just about making sure they work reliably; it can also significantly affect efficiency. A regular check-up, or energy audit, will help extend it’s lifespan, optimise it’s performance, and reduce energy consumption.
Businesses should take advantage of predictive and preventive maintenance tools and technology. These tools help to constantly keep air compressors working at their best, and reduce air compressor maintenance costs.
By keeping up with maintenance for your compressed air system, you can achieve maximum efficiency of the compressed air system. Changing filter elements at the correct time within the maintenance schedule, for example, reduces pressure drops, and alleviates additional strain on the compressor
5. Respect the Service Life of Your Machine
Have you noticed that your compressed air equipment isn’t performing as well as it used to? That’s to be expected, but it’s also a great reminder that you shouldn’t hang on to machines longer than necessary. After all, they can become quite expensive to operate over time – both in terms of energy consumption and operating costs.
Significant advances have been made in compressor technology – like the GA VSDᣵ series, an evolution of variable speed drive (VSD) technology that can reduce energy consumption by up to 60%. And when the time comes for you to upgrade, investing in these more efficient machines typically pays for itself quickly, as operating expenses decrease.
6. Recover Heat
Compressing air generates a lot of heat. Businesses can either allow this heat to go to waste, or harness it for other purposes.
New technologies make it possible to recover and reuse most of the heat lost during compression. This heat can then be used to heat water, replace furnaces, or even dry things.
In many cases, major investments are not needed to make this happen. Simply connecting the compressor hot outlet to existing HVAC ducting during winter is enough to help heat up a facility.
Another technique is to use an energy recovery kit, which can heat up water for use in another location in the building.
7. Use Green Energy
As we know, compressed air systems consume a lot of energy, so business owners should consider going green. Installing clean and renewable energy sources like solar panels and wind turbines to power production processes will reduce energy costs in the long run.
It’s widely known that investing in these technologies pays off both financially and environmentally. The long-term savings on energy costs are significant, and the reduction in CO2 output will help reduce your carbon footprint.
These suggestions can help you meet strict regulations, reduce your carbon footprint, and decrease energy costs. Some of these tips, like rudimentary leak protection, involve very little investment and minimal effort to implement.
