Technical Updates  

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

The 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.

Gaskets Patented Hybrid Lock System

Lock-in method

Lock-on method

Optimized unique shape of the gasket

Highest production standards


Model JAG Plate Heat Exchanger Design

Metal roller

Connection size: DN32 to DN250
