Improved sustainability and efficiency for bottle and packaging unit transport
The Viennese bottling plant reduced energy costs with 40 MOVIGEAR® mechatronic drives. The integrated SNI technology also reduced the installation expense.
The soft drink bottling plant is focused on reducing CO2 emissions as well as energy costs. MOVIGEAR® drive systems provided unexpectedly high energy efficiency for transporting PET bottles and packaging units.
MOVIGEAR® allowed Coca-Cola HBC Austria GmbH to reduce energy consumption by 75%.
Improved sustainability and significant reduction of the CO2 footprint in the production area are the primary focus for the Coca-Cola Group's corporate policy. Production and bottling plants worldwide feel that it is there obligation to achieve this climate objective. Coca-Cola HBC Austria GmbH, in the Austrian capital Vienna, has also set itself this aim and is upgrading its plants accordingly.
With the promise of energy savings of up to 50%, thanks to innovative mechatronics for the drive technology, SEW-EURODRIVE received the order to upgrade transport line 2a at the end of 2009. In the area from the shrinkpacker to the palletiser, the plant processes PET bottles with a fill quantity of 0.5 to 2.5 liters.
We managed to exceed our customer's expectations: The consistent application of our mechatronic drive technology, with its unmatched energy efficiency, and other additional measures reduced the transport line's energy consumption by 75%.
This is demonstrated by the supporting measurements provided by Wien Energie GmbH. The public utility is involved in the entire modification, right from the start, with detailed energy consumption calculations. The independent results speak for themselves:
a total energy saving of about 75% compared to the previous drive and control technology
CO2 reduction of about 41,000 kg/year (based on the relatively positive CO2 footprint in Austria, at a European level)
Maximum energy efficiency and low installation expenses reduce costs
Coca-Cola HBC significantly reduced its operating costs thanks to the use of MOVIGEAR® drive systems. This is not just due to the outstanding 75% energy saving. The power supply and communication via SNI technology (Single Line Network Installation) also contributed to the cost reduction.
SNI technology allows for energy supply and communication transmission via a single shielded cable. This allowed the plant operator to significantly reduce the number of required components as well as their installation expenses.
Complete modification of the drive technology in just 3 days
This was made possible by the modification team in the bottling plant. The technicians completed the mechanical conversion of the plant over a long weekend, from Friday morning to Sunday evening. During this short period, they removed the old drives as well as the cabling, completed the mechanical and electrical installation of the new drives and performed the startup activities. Coca-Cola HBC was able to restart production on Monday morning.
Amortisation of the investment within the first year
This considerable contribution to the reduction of the overall costs and operating costs ensured that the investment in the plant modernisation paid for itself in less than a year. This ideal efficiency result, in every respect, and other benefits were made possible by:
40 MOVIGEAR® of the energy efficiency class IE4 in SNI technology (Single Line Network Installation)
Supporting control measures, such as speed optimisation and improved jam shutdown by the integrated PROFIBUS
SNI principle (Single Line Network Installation): Only one cable used for energy and information transfer
Simplified plant planning and plant layout due to the reduced number of required components
High degree of protection
Tested resistance to normal cleaning agents
Hygienic surface design for applications in the hygiene sector
Energy saving and the reduction of CO2 were the primary objectives for the transport line upgrade.
The new mechatronic drive technology with MOVIGEAR® and SNI technology allowed Coca-Cola HBC to significantly exceed their set objectives: the 75% energy saving ensured that the investment paid for itself in just one year.
Thus SEW-EURODRIVE came forward with a proposal to optimise the gear units, which we use for our conveyor belts, by installing a new technology, the MOVIGEAR®. A plant was selected for the installation of 40 of these drive units.
At the time, we could not imagine what this would mean for us. Today, I can say that this technology allowed us to achieve an energy saving of 75%. For us, this means that we will take further steps with SEW-EURODRIVE to implement this improvement both at this site and at a site for mineral water.
We installed a long-term measurement unit at the PET bottling plant to record the energy consumption and the load behavior for the duration of one month. This measurement allowed us to demonstrate that the modification of this PET bottling line enabled an energy cost saving of 75 percent. This corresponds to an approximate amount of 41 tons of CO2 emissions saved every year.
