APEX Free-flow is a technology applied to reduce fouling and pressure-drop for easy operation of plate-type heat exchangers. It is the primary Technology applicable to all our plate-type heat exchangers (CORPEX and V-FLEX heat exchangers).

Heat transfer surfaces are formed and/or arranged in a way which ensures no obstruction for the bulk of the processed fluid flow.

APEX Free-flow Technology maintains a reduced obstruction in the flow path in-between the parallel smooth plates. There is no flow separation and the velocity profile is well defined: a thin laminar sub-layer adjacent to the wall and a turbulent flow core.

This flow configuration results in a relatively low level of energy dissipation. Therefore, this flow type is the most efficient, resulting in an optimum compromise between a high heat transfer coefficient and a reduced pressure drop.
