Flender Implements Waste Heat System to Cut Gas Use and Emissions

Flender has introduced a new heating system at its Bocholt facility that reuses waste heat from hardening furnaces to warm its buildings. By incorporating a high-capacity heat pump, the company says it can reduce natural gas use by 2.4 million kilowatt hours annually and lower CO2 emissions by 400 tons. This process helps make its production more sustainable by cycling heat back into the system instead of relying solely on gas.

The heating system works by extracting heat from cooling water used in the hardening process, transferring it through a heat exchanger and using a 622-kilowatt heat pump to raise the water temperature to 60 degrees Celsius for building heating. The water then returns to cool the furnaces in a closed-loop system, which the company explains maximizes efficiency. Construction included new water piping across the site and updates to the heating system to enhance energy savings.

“We have a significant responsibility to society and our climate to make our production as sustainable as possible. This new heating method is a major milestone toward our goals, demonstrating our commitment to reducing resource consumption and lowering our carbon footprint.” said Flender CEO Andreas Evertz.
