The heart of the compressors is processed in the Airtec B shop of Atlas Copco Airpower in

Wilrijk: the cast iron casings, in which the rotor is placed. This has recently been done in an even

more automated cell, at four Starrag Heckert machining centers. Once this cell is fully

operational, cast iron housings can be machined in small batches for up to 70 hours, unmanned.

Certainty about the quality of the coolant is then a crucial success factor in the overall process.
