Plate & Shell

The plate and shell heat exchangers from Sondex utilize a fully welded plate pack, laser/TIG welded together and mounted inside a traditional cylindrical shell. With a high thermal efficiency and lower purchase cost, the Sondex plate and shell heat exchanger combines the benefits of a traditional shell & tube type heat exchanger but with the high efficiency provided for in a plate type exchanger.
