Block type heat exchanger

liquid/liquidcorrosion-resistant

DIABON block heat exchangers of this design consist of DIABON graphite blocks that incorporate horizontal and vertical passages. The blocks are stacked on a baseplate with corrosion-resistant gaskets between each. A steel shell fits over the block column and is bolted to the baseplate. The block column is secured by a top pressure plate bolted to the steel shell. The joint between the steel shell and top header is sealed with an O-ring to allow free movement of the shell. The difference in thermal expansion between graphite and steel is compensated for by helical compression springs.
