Saving more than 600 tons of CO2 per year
The colorful chocolate squares of Ritter Sport are world-famous. From the Swabian Waldenbuch, the company exports its treats to more than 100 countries. ENGIE Deutschland has also helped to ensure that chocolate production is as energy-efficient as possible: As part of an extensive efficiency project, the energy consumption for air conditioning a production building measuring around 6,000 square meters was reduced sustainably and over the long term.
Development of a customized system concept that included the retrofitting of variable volume flow controllers on four central air-conditioning units in the production building, which controlled the supply and exhaust air according to demand. In this way, the average volume of air conveyed was reduced from the previous 300,000 m³/h to around 165,000 m³/h. This is a significant reduction. Approximately 50 % of the electrical drive energy is saved. In addition to the energy savings, the required room temperatures are maintained more precisely.
The Federal Ministry of Economics and Energy (BMWI) has funded the measures with a six-figure sum to save electricity, as a special example of energy efficiency in industry. The funding shortens the payback period by 2 years.
All measures were implemented during ongoing production operations.
