Additionally corrugated distribution area is designed to enhance turbulent flow in the entrance part of the plate. It also allows even flow through the plate which increases heat transfer by optimal use of its surface area. Specifically corrugated distribution area strengthens the plate and increases the stability of the whole construction. Carefully designed groove together with specially modelled gasket makes the exchanger withstand high pressure.

Triple Plate Positioning System Features
• Gasket aligning system – special protruding
• Elements align the plates in relation to one another
• Point locking system – dedicated corrugated
• Elements on the plate
• Stellar suspending system – alignment in position to the upper and lower bar

Hexonic-JAG-Heat-Exchanger-Heat-DistributionThe Finite Element Method Analysis (FEM) optimized the design of the JAG plate heat exchanger in terms of strength, mainly by improving the stress distribution on the cover plates and modifying the location of the fasteners, which contributed to the extension of the operating parameters.
