Inherited from our automotive background, all our fuel cell compressors produced, are assigned a unique serial number with full traceability. 

The serial number reveals all critical information about each component and its lot number, enabling full traceability all the way back to the melter/material certificate, quality control report etc. 

Additionally, the extended end-of-line test results are stored under the serial number, along with its unique encoder off-set tuning value (mobile only).
