SmartBLOCK-Fully welded heat exchanger
SmartBLOCK is a welded plate type heat exchanger that can be opened at both sides and designed without any seal gaskets installed between heat transfer plates, it can provide large heat transfer area within a compact space, and can be opened at two sides for cleaning.
SmartBLOCK is such designed that the heat transfer plates, frame columns and cover panels are bolted into a plate bank assembly, this assembly is bolted with the rigid rectangle shaped side panels to form a unit. Sealing strips (gaskets) are installed between the plate bank and side panels (4 gaskets are required for each heat exchanger). Side panels are served to separate the fluid loop and enhance mechanical strength, and removable baffles can be installed for each fluid loop.
