SIGMATWIN DOUBLE-WALL PLATE

SIGMATWIN – Enhanced security in production processes. with internal gaskets with laser-weldings We designed the SIGMATWIN double-wall plate to achieve the specific demands for a heat exchanger plate as a safety plate. Construction 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 only in the section of the four holes either with laser-weldings or with flat ring gaskets. In case of a plate crack the leakage at first escapes into the gap between the two plates and...
