DIABON block heat exchangers of this design consist of DIABON graphite blocks with horizontal and vertical passages.
The block is stacked on a corrosion-resistant base plate
The steel shell block with gaskets between each sits on top of the column and is bolted to the base plate
An upper pressure plate of the block column is bolted to the steel shell. Joint between steel shell and top
sealed with an O-ring cap
Allow free movement of the shell.
The thermal expansion difference is compensated by helical compression springs between graphite and steel.
