Abstract A plate heat exchanger includes a package of heat transfer plates. The heat transfer plates are provided with inlet ports therethrough forming an inlet channel through the package. A sealing means is arranged between the heat transfer plates and forms, together with the heat transfer plates, a first flow passage for one fluid in every second plate interspace and a second flow passage for a heating fluid in each of the remaining plate interspaces. The inlet channel communicates with each first flow passage through at least one inlet passage while being blocked from communication with each second flow passage by part of the sealing means located in a first sealing area that extends around the inlet channel. Every two adjacent heat transfer plates which delimit the first flow passage have an essentially tight surface abutment against each other in a second sealing area. The inlet passage is delimited by at least one of the two adjacent heat transfer plates between its inlet port and the first sealing area.
