PRODUCT INTRODUCTIONHT-Bloc is made up of plate pack and frame. The plate pack is certain number of plates welded together to form channels, then it is installed into a frame, which is formed by four corner girders, top and bottom plates and four side panels. The frame is bolted connected and can be easily disassembled for service and cleaning. There are three different plate patterns, corrugated, studded, and dimpled pattern, to meet different process requirements.
WORKING PRINCIPLESThe cold and hot media flow alternately in welded channels between the plates. Each medium flows in a cross-flow arrangement within each pass. For multi-pass unit, the media flow in countercurrent. The flexible flow configuration makes both sides keeping the best thermal efficiency. And the flow configuration can be rearranged to fit the change of the flow rate or temperature in the new duty.
The plate pack is fully welded without gasket;The frame can be disassembled for repair and cleaning;Compact structure , high thermal efficient and small footprint;The unique design of π angle TM prevent "dead zone ";The butt welding of plates avoid risk of crevice corrosion;The flexible flow configuration can ensure consistent high thermal efficiency;Short flow path fit low-pressure condensing duty and allow very low pressure drop.A variety of flow form meets all kinds of complex heat transfer process.
