In October 2015 the company, which produces, manufactures and distributes Coca-Cola brands from the site in Jordbro, changed its compressed air supplier to Tryckluftspecialisten and the CompAir brand. 

Patrik Almström, sales engineer and project leader at Tryckluftspecialisten explains: “Coca-Cola Enterprises is one of the largest bottlers of soft beverages in Europe and the plant uses compressed air for general production purposes.

“The previous compressors were energy intensive, noisy and consuming about 22,000kW of electricity a week. As compressed air demand is continuous, the facilities management team was keen to look at options for improving efficiency and performance.

“We specified two CompAir L75 regulated speed systems and two CompAir L55 fixed speed machines. The compressors work in tandem to meet demand at optimum energy efficiency. The SmartAir Master continuously rotates the control system.

“All four compressors are controlled by a CompAir SmartAir Master system that manages the compressed air supply across the site. The system calculates precisely how much air the plant needs in real time and optimises the compressor output accordingly, by continuously rotating the master pairs to equalize running hours.”

Seamless installation

The site could also not afford to be without compressed air during the installation and commissioning process. Kim Hesselius, unit & facility manager at Coca-Cola Enterprises explains: “During installation we still required sufficient compressed air for our manufacturing processes. The commissioning of the new machines ran throughout October 2015, with Tryckluftspecialisten staggering the installation of one compressor at a time to make sure we could always maintain production output. It was a great service.”

Jonas Wittefeldt, environmental manager at Coca-Coca Enterprises, adds: “The installation went really well and the project also fits perfectly with our sustainability agenda as saving energy is one of our top priorities.”

Tryckluftspecialisten installed heat recovery systems on all the machines to provide hot water to power the site’s heating system.

Not only has site energy consumption been reduced by about 60%, but at least 80% more heat has been recovered than previously, resulting in total savings of about 1,000,000kWh of energy per year.

Jonas Åström, purchasing manager, concludes: “At Coca-Cola Enterprises we are continually looking for ways to improve our sustainability targets across the company. Even though the machines have only been on site for a month we are already achieving great results and we are looking forward to seeing continued energy savings.”
