5.5. Connector Grid and Bosses
The connector grid divides the plate heat exchanger into separate sections that may
operate independently. The connector grid is equipped with removable connector
bosses (Figure 15).
The connector bosses can also form the connections between sections of the plate heat
exchanger and provide external connections to and from these sections. On some
models, two connections can be provided in the same connector grid boss with
connections to both adjacent sections.

5.6. Solid Divider Plate
A divider plate (Figure 16) is typically a solid plate between 6mm and 10mm (1/4 in. –
3/8 in.) thick. The divider plate has the same outer shape as the flow plates. A divider
plate is used to divide a heat exchanger into two separate operating sections and have
no external connections but may allow flow from one section to the next through their
ports.
