Energy-Efficient Cooling for Confectionery Production in Germany

To uphold its climate-neutral status across all German sites, Katjes required a cooling system tailored to its needs, one that could operate around the clock, deliver high efficiency, and fit within limited space. The solution had to ensure reliability and support the company’s sustainability goals while enabling production growth.

To meet its climate-neutral production goals and ensure reliable 24/7 operation, Katjes adopted a water-cooled York YZ Magnetic Bearing Centrifugal Chiller as part of a compact container solution. This design allowed all components; hydraulic systems, pumps, and controls; to be housed in a single, space-saving unit, making installation possible during ongoing production. The chiller’s magnetic bearing technology eliminates the need for oil, reducing maintenance and wear, while its ability to operate with mechanical free cooling optimizes energy use throughout the year.

The new chiller system helped Katjes improve operational efficiency and support its sustainability goals. By replacing two older units with a single advanced solution, the company achieved higher performance and reduced energy consumption while maintaining reliable, year-round operation.

• Efficiency rating increased from 6 to 9
• Lower electrical power demand for compressors and pumps
• Continuous operation with minimal wear
• Enables climate-neutral production across all German sites
• Uses Low-GWP refrigerant R1233zd
