The upgrade was handled by MAN PrimeServ, the company’s global aftersales brand. It re-established safe and reliable operation and long-term availability of spare parts and service for Deutsche Bundesbank’s plant.
Since 1998, Deutsche Bundesbank ” one of the largest central banks in the world ” has operated the plant, which is driven by the MAN Diesel 6L 32/40DF engine.
The heat generated by the plant is used for heating and to produce hot water. During summer, the heat can be used for cooling by utilizing absorption refrigeration machines.
“While the 19-year old engine was still mechanically flawless, the old electronic engine automation system was causing problems,” said Dr Thomas Spindler, head of PrimeServ Augsburg Upgrade & Retrofit department.
“Compare it to your smartphone: even though the old hardware itself might still be fine, newer generation software will achieve better performance and offer more user-friendliness. At some point you need to upgrade your phone to the recent operating system to keep it running.”
MAN PrimeServ Engineering updated the engine with its Safety and Control System (SaCoSone). Since 2008, the system is used on hundreds of diesel and dual-fuel engines both in marine and stationary plants.
Thomas Pollak, development engineer at PrimeServ, explained that “it was the first conversion of an old dual-fuel engine automation system into a full SaCoSone system. We used the system for the 51/60 DF engine as a base, which is the 32/40 DF’s big brother so to speak. That way we did not have to program a new product for an old engine from scratch.”
