Producer of cardboard packaging saves 20% on energy per year

The customer's utility room consists of five competitor compressors and one competitor Central Controller.

The Atlas Copco team went on site and conducted an AIRScan audit of the entire compressed air system. Based on the AIRScan Report, a proposal was made to optimize the utility room on several areas.

• Three of the five competitor units were replaced with Atlas Copco units. The two remaining competitor units stayed as backup.

  
  

• The three new Atlas Copco compressors were each equipped with an Energy Recovery Unit, which captures the heat that is being generated during compression. The recovered heat is stored in a 6m³ tank and used in industrial processes, enabling the customer to save on boiler and fossil fuels.

  
  

• The competitor Central Controller was replaced with an Optimizer 4.0 Central Controller to reduce the unloaded hours of loaded and unloaded compressors and generally optimize the entire utility room.



• Pressure sensors were installed to measure the actual savings. Thanks to SMARTLINK, the customer can accurately monitor and track the energy and CO₂ savings. 

The customer's optimizing efforts resulted in 20% energy savings, equal to 169 300 kWh per year. This translates to an annual cost reduction of EUR 37 000. In addition, the customer achieved a CO₂ reduction of 71 tons a year. These savings were confirmed by the customer's own calibrated measurement devices.

On top of that, the customer saves extra on boiler and fossil fuel costs thanks to the Energy Recovery Units.
