Abstract: A fluid connector for providing an inlet/outlet connection to a connecting grid of a heat exchanger is disclosed in which the connector has a tubular body formed with an integral outwardly directed flange by means of which a fluid tight connection to the connecting grid can be achieved. The flange may be sealed relative to an aperture in a plate of the connecting grid. Alternatively, the aperture may be provided with a structural ring and the flange sealed relative to the structural ring for adapting the aperture to the size and/or position of the flange. A set of structural rings may be provided for use of the connecting grid with different connectors. The structural ring may allow the connector to be detached without disassembling the connecting grid. The aperture may be closed by a blanking disc.

Abstract: A plate heat exchanger includes first and second plates, a package of heat transfer plates arranged between the first and second plates, and a closure system. The closure system includes a plurality of tie bar assemblies. Each tie bar assembly includes a tie bar extending between the first and second plates, and a threaded member threadedly engaging the tie bar. The closure system and the first and second plates are relatively arranged and configured such that relative rotation between the tie bar and the threaded member of each tie bar assembly is operative to move the first plate towards and away from the second plate to close and open, respectively, the plate heat exchanger. The plate heat exchanger is arranged and configured such that the heat transfer plates can be removed from the plate heat exchanger without relocating any of the tie bars.
