The gaps between the corrugated plates form flow channels, which primary and secondary media flow through alternately. Flow directors in the shell side prevent any bypass – flow between shell and plate pack, which reduces thermal performance.
The flow direction of both media can be arranged as counter-flow, co-current or cross-flow. The heat is transferred via the corrugated plates, which create turbulence and enhance heat transfer. When one or both media are evaporating or condensing partly or completely, it is called a two-phase application.
the most common form of flow configuration
for a reduced resistance on the primary and secondary side
for maximum temperature differences at the inlet, or to avoid temperature crossing
By means of deflections the plate and shell side can be configured for multi passes. This increases the thermal length.
For large volumetric flows on the plate side
For large differences in volumetric flow rates between plate and shell side
For optimizing the pressure loss and heat transfer on both sides
XPS plate heat exchangers are available in five sizes and with different corrugation patterns, i.e. with different corrugation angles and pressing depths.
