Founded as machine works in 1899, Aabenraa Motorfabrik built their first marine engine in 1904. Since then many different engine types have been produced for many different purposes, but for many years CALLESEN engines have been used for propulsion of small ships like fishing boats, freighters, tugs and ice breakers. In 1995 Aabenraa Motorfabrik took over the production of BUKH diesel engines, extending the delivery programme to include small engines for pleasure boats, lifeboats and generating sets. Further, Aabenraa Motorfabrik have the facilities to act as sub-suppliers of various machined goods.
