Abstract
A plate heat exchanger comprising a stack of heat transfer plates which together with sealing means define first and second flow passages for first and second fluids respectively. The heat transfer plates are formed with through holes defining an inlet channel communicating with the first flow passages and a gasket is arranged around the through holes in the gap between each pair of heat transfer plates forming a first flow passage. The gasket can be inserted in and/or removed from the gap between a pair of permanently joined heat transfer plates and can include a tube for producing a pressure drop for flow of fluid from the inlet passage to the first flow passage.
