From ten to one bar

Ensuring the precision of a component isn’t always just a matter of highly accurate measurement. Unwanted particles can still escape detection. That’s why components need to be washed. In 2024, we made our washing process more energy efficient.

Nearly all components from our production go through an alkaline wash, where the majority of oil and metal shavings are removed through various cleaning stages. To reduce energy consumption, we tested lowering the spray pressure from ten to one bar in certain parts of the process – without compromising the result.

”In fact, the results have actually improved slightly, as it turns out that oil is easier to separate at lower pressure,” says Emil Claesson, wash technician.

We also reduced the temperature in all five washing tanks by 3 to 10 degrees and improved their insulation to help retain heat for as long as possible.

”For long-term evaluation of the energy optimisation, we’ve also installed electricity meters on the washers to compare and monitor power consumption,” adds Patrik Hessne, wash technician.
