How does a plate heat exchanger work? Heat transfer theory The law of physics always allows the driving energy in a system to flow until equilibrium. Heat dissipates when there is a temperature difference. A heat exchanger follows the equalisation principle. With a plate heat exchanger, heat cuts through the surface and separates the hot […]

The two fluid medium in the system follows a counter flow path with; one fluid getting in from top while leaving at bottom and another entering at bottom and leaving at top. The rate of flow is controlled in the system to avoid negative effects of turbulence flow such as erosion. The type and length […]

A single metal plate can have high or low tetra pattern which aids in efficient heat exchange between the liquids. These corrugated structure types create turbulence in the flow; creating much better heat exchange between the two media. The complete plate pack assembly is as such; that the hot medium flows on one side of […]

Gasketed Plate Heat Exchangers The plate-and-frame or gasketed plate heat exchanger (PHE) consists of a number of thin rectangular metal plates sealed around the edges by gaskets and held together in a frame The frame usually has a fixed end cover (headpiece) fitted with connecting ports and a movable end cover (pressure plate, follower, or...
