Establishing new benchmarks for the industry

The MAN Energy Solutions product development strategy is to design GenSet solutions that produce energy at the lowest possible cost per kW without compromising on quality. This strategy requires a resolution of the conflicts inherent between five key market requirements: Operation on the cheapest fuel, easiest possible daily maintenance procedures, longest safe intervals between overhauls, unlimited load patterns, and worldwide environmental regulations. Over many years, MAN Energy Solutions has achieved the right balance between these requirements by applying an innovative approach to engine and generator design. This approach has assured MAN GenSets a substantial global market share and the opportunity to set new standards in the world market.
