Moran Iron Works was awarded the contract to fabricate a complex silencer and plenum heat shields for a 40 plus year old Frame 5 unit. This silencer stack had three levels of baffles for maximum performance. The plenum heat shields were replaced due to age and replacements were installed without the removal of the diffuser.

This unit was shipped via oversized load to Douglas in one piece with lifting lugs installed for both rolling and lifting.

The project was completed and delivered in three months.
