An important commodity. In industry, compressed air is produced, for example, with screw compressors.
Compressors can also be used to check tire pressure. <\/p>\n

in machine shops and the forest industry.<\/p>\n
as a utility right after electricity,\u201d says Sami Uusi-Erkkil\u00e4.
He is the CEO of Smartair And Energy Oy, a company specializing in compressed air and its energy savings.

Not everyone has yet thought about making use more efficient.
"Its use is sometimes reckless. According to various sources, up to 10\u201320
percent of the compressed air produced is lost as leaks into the air. You can see this when you look around.

of electricity consumption is spent on producing and processing compressed air. Approximately 20 percent
with leakage rates this would mean wasted energy of around 757 gigawatt hours
per year.<\/p>\n
Areas of responsibility include industrial energy efficiency and energy production.
Leaks are still a problem, but compressed air production has improved
more energy-efficient solutions, such as speed-controlled compressors.

In industry, compressed air is used, among other things, for automation, equipment and machinery.

Unnecessary consumption can be prevented by identifying and repairing leaks.
Measuring equipment suppliers offer technology for leak detection.
According to Uusi-Erkkil\u00e4, it is also important to train employees.<\/p>\n
Compressed air is an everyday occurrence. It is worth making monitoring compressed air leaks a part of the factory's routine.

As a mechanical engineer, Uusi-Erkkil\u00e4 knows that compressed air can be used to clean, for example,
objects or surfaces quickly and efficiently. However, compressed air may be used
recklessly.<\/p>\n
Erkkil\u00e4 is horrified.<\/p>\n
by cooling it with compressed air.

"It's best to avoid using it if there are alternative methods," Kiuru encourages.
It is worth recovering and utilizing waste heat. That is the fourth thing that prevents leaks

Ten percent is electrical energy consumed for compressed air.
Uusi-Erkkil\u00e4 regrets that there is still a lack of information on the use of compressed air and energy consumption.
Relatively little reliable research data. Many calculations are estimates.
If the workshop is working in two shifts, compressed air leaks mean
tens of megawatt hours of unnecessary electricity consumption annually. With current
Electricity prices are even tens of thousands of euros.<\/p>\n
