Multi-sectional heat exchanger

A sectioned heat exchanger comprising at least two heat exchanger units and at least one separating element adapted to be positioned in connection to a heat exchanger unit of a sectioned heat exchanger, the separating element comprising first openings adapted to align with first heat exchanger openings forming inlets of a first flow path (A) and a second flow path (B), respectively, through the heat exchanger unit, the separating element further comprising second openings adapted to align with second heat exchanger openings forming outlets of the first flow path (A) and the second flow path (B), respectively, through the heat exchanger unit, where the first openings are formed with first valves adapted to close for fluid flow to the first (A) and/or the second (B) flow path through the heat exchanger unit and where the second openings are formed with second valves adapted to close for fluid flow from the first (A) and/or second (B) flow path, wherein the first valves are formed with valve stems, each operated by an actuator, wherein the second valves for flow path (A) are connected to the same valve stems as the first valves for flow path (A), wherein the second valves for flow path (B) are connected to the same valve stems as the first valves for flow path (B), thereby providing coordinated control of the first valves and the second valves, and

• wherein each of the at least one separating element is arranged between two of the heat exchanger units, thereby separating the two heat exchanger units.
