The SIGMATWIN double-wall plate heat exchanger has been specifically designed to meet specific requirements for a heat exchanger as a safety plate.
Contruction and Functional Concept
Instead of a single SIGMA plate we apply a SIGMATWIN plate pair, which has been moulded together and put into each other. The sealing of the gap is realised with flat ring gaskets or laser welded.
This prevents a contamination of the two fluids / products which are engaged in the heat exchange process in the event of a leakage. A leakage escapes into the gap between the two plates and can be seen during an inspection.
SIGMA plate heat exchangers equipped with SIGMATWIN double-wall plates can be opened like standard plate heat exchangers for inspection, or maintenance purposes.
