An energy converter comprises functional elements that comprise at least the fol lowing: an electrical turbo-machine (101) for converting energy contained by va porized working fluid into electrical energy, condenser (102) for condensing the vaporized working fluid outputted by the electrical turbo-machine, and a feed pump (103) for pumping the condensed working fluid to a vaporizer. The energy con verter can be based on for example the Organic Rankine Cycle. The energy con verter further comprises a frame element (140) arranged to act as a mechanical support frame for the functional elements. Furthermore, the piping between the functional elements is at least partly implemented as ducts of the frame element. Therefore, the mechanical structure of the energy converter can be compact, ro bust, and cost effective to manufacture.
