For all of its benefits, compressed air has always had one drawback: It takes a lot of energy to produce it. At a time of high energy prices and the need for greater sustainability, that can be a real challenge. Fortunately, there are now plenty of innovative technologies that allow you to produce your compressed air efficiently. And, to reduce your energy consumption even more, you can check out these energy saving tips for your compressed air installation.
When using a traditional fixed-speed compressor, your energy expenses often make up 70% of your total cost of ownership – or even more. A modern unit with variable speed drive (VSD) technology, however, can reduce your energy consumption by more than 50%. And these savings quickly add up.
On average, leaks add 20% to the energy bill of compressed air users. That is why preventing and plugging them should be high on your list of priorities.
Even a tiny leak can be very expensive: A 3 mm leak at a pressure of 7 bar can cost you $1,300 annually. To guarantee that these tiny holes don’t become a big problem, make sure that you have installed a reliable piping network.
Periodically, you should use ultrasonic leak detection technology to find new leaks. And, in the meantime, if you hear a hissing sound coming from your pipes, just cover the suspected leak with soapy water. If you see bubbles appear, you should take action.
Obviously, you want to make sure that your pressure is high enough to meet your demand. But you don’t want it to be higher than necessary. For each bar that you can reduce your pressure, you can lower your energy consumption by about 7%.
A frequency-controlled compressor often provides an adjustable operating pressure (usually ranging from 4 to 13 bar). That can help you get the pressure just right and save money.
Compressing air generates a lot of heat. Don’t let it go to waste! For example, use a heat exchanger to heat steam boilers, process water or your central heating system. Yes, this requires an initial investment, but it is an investment that will quickly pay for itself.
Optimize the operation of multiple compressors by using a central controller. It guarantees that the correct combination of compressors is used with the right system pressure. This allows you to get the most out of all of your machines. That not only improves the efficiency of your compressed air system but also its longevity and reliability.
One of the most important energy saving tips for your compressed air installation is to ensure that it is properly maintained. This guarantees that your system remains in optimal condition and is at its most efficient. Remember: When your compressor is in peak condition, you save!
Many operations are highly inefficient. Processes are changed, machines are replaced… all without considering whether that will affect the compressed air system or the system pressure. To prevent this from happening to you, periodically review your piping system. You want to make sure that the compressed air reaches its definition in as short a distance as possible. Any detours will cost you money.
By implementing these energy saving tips for your compressed air installation, you will be able to reduce your electric bill. At the same time, you can reduce your environmental footprint and do your part for a greener tomorrow.
