COMPRESSED AIR
used for a variety of different applications, such as heating water, replacing furnaces or in drying processes. In many cases, heat recovery does not
require major investment. For example, you can simply connect the compressor hot outlet to your HVAC ducting in the winter to heat your facilities, or you could install an energy recovery kit and heat up water for use elsewhere in your facilities. 7. Use green energy There is no way around the fact that
new and more efficient equipment will often pay for itself quickly. 6. Recover heat Compressing air not only consumes a lot of
energy, but it also generates a lot of heat. You could simply allow this heat to go to waste, but if you do, at least make sure it is not released inside your compressor room to keep the ambient temperature low - see point 3. A better alternative is to harness this heat, effectively reusing the power consumed during the compression process to reduce your energy bill. The recovered heat can be
compressing air uses quite a bit of energy – at least not yet. However, what you can do is make sure that all or most of it is green energy. This may involve installing solar panels or wind turbines to power your production. While this can constitute a significant investment, many governments will now subsidise renewable energy installations as part of their climate protection strategy. On-site renewables can certainly lower your costs and reduce your CO2 output. Talking to the experts and doing the maths will prove whether this is a good investment. If you want to reduce your compressed air
consumption but are unsure where to start, Atlas Copco offers its AIRchitect service, which
is free to any compressed air user. We will monitor your compressed air usage for 7-10 days. Using the collected data, our experts compile a comprehensive report tailored specifically to your operation, and make recommendations on how you can save energy. It’s entirely up to you whether you then implement them. For more information, read Atlas Copco’s
