Power Generation


Change is constant. Our systems adapt. It could be your business demands, a new location or the introduction of new regulations. An mtu upgrade can help you meet whatever changes come your way.


We adapt to your evolving needs.

Your generators may be needed in another country with different emission regulations.

You may want to raise or lower their output. Whatever the cause of the change, we can try to find an mtu upgrade to suit your needs.

NOx Box standalone solution

For the mtu 400 Series with MMC V6 controls and older: Standard mtu NOx sensor. Does not require no further sensors for temperature or pressure on modules.

NOx sensor retrofit package

Determines daily average values of NOx on the 400 and 4000 Series for natural gas and biogas applications.

Oxidation catalyst

Reduces formaldehyde emissions to let you meet legal emission targets and enable formaldehyde bonus.

Performance changes

Adapt the performance level of your engine with changes to software and hardware. Requires individual review and approval.

Emission adjustments

Adjust the emission values and certification of your engine to changed application scenarios. Requires individual review and approval.

Label changes

Change emission-related labels to suit different locations. Emission calibration may be necessary. Requires individual review and approval.

Calibration changes

Calibration changes include all conversions based on customer orders on engines/systems with regard to power, application group, frequency and certification (incl. emission level).

X4 maintenance switch

Disables the X4 cable automatically and delays engine start. This allows time for oil pressure to build, preventing engine failure and serves as a visual indicator to ensure all steps are performed after generator set maintenance.
