A brazed plate heat exchanger (100) including a plurality of first and second heat exchanger plates (110, 120), wherein the first heat exchanger plates (110) are formed with a first pattern of ridges (R1) and grooves (G1), and the second heat exchanger plates (120) are formed with a second pattern of ridges (R2a, R2b) and grooves (G2a, G2b) providing contact points between at least some crossing ridges and grooves of neighbouring plates under formation of interplate flow channels for fluids to exchange heat, said interplate flow channels being in selective fluid communication port openings (O1, O2, O3, O4). The first pattern of ridges and grooves is different from the second pattern of ridges and grooves, so that an interplate flow channel volume on one side of the first heat exchanger plates (110) is different from the interplate flow channel volume on the opposite side of the first heat exchanger plates (110). The heat exchanger (100) is provided with a retrofit port heat exchanger (400). A system and a method are also disclosed.

A heat exchanger including a sealed housing and a body positioned inside the housing, the body including a stack of least one first assembly of first and second plates pressed against each other, between which flows a first fluid, and at least one second assembly of third and fourth plates pressed against each other, between which flows a second fluid, the first and second assemblies being arranged so that they transfer heat between the first and second fluids. This configuration limits the risk of leaks and mixing of the two fluids.
