Welded Heat Exchangers - Shell & Plate

When To Consider Shell & Plate Welded Heat Exchangers

Whenever you are confronted with heat exchange under difficult physical or flow conditions, the Tranter Shell & Plate Exchanger is worth consideration (Download technical article on good engineering practice in Shell & Plate applications.pdf). The unit can overcome footprint constraints, extreme pressures/temperatures, fouling/scaling conditions and corrosive attack with liquids, gases, steam and two-phase mixtures. The turbulent flow created by the corrugated plates produces high heat transfer efficiency and limits fouling, or freezing in refrigeration/cryogenic service. The exchanger’s wide temperature/pressure ratings offer good performance with natural refrigerants such as ammonia and carbon dioxide.

The exchanger can handle close temperature approaches. Small hold-up volume provides fast start-ups and close following of process changes. Refrigerant charges are significantly low in refrigeration and cryogenic service, which results in lower operating and disposal costs.

The Tranter Shell & Plate Exchanger is designed for pressures to 100 barg (1450 psig) and temperatures from -58° to 900°C (-50° to 1650°F) for standard range units. Extended range units are available. Fluids can undergo phase change on either the plate or shell side. The exchanger is particularly suited to applications having a flow imbalance, allowing higher flow rates on the shell side. The Tranter proprietary welding method used for the port hole and perimeter welds has been preferred for demanding chemical processing applications.

Tranter Shell & Plate vs. shell & tube equal duty footprint 

Amazing, but true. For equivalent duty, the Shell & Plate Exchanger’s significantly higher heat transfer rate versus the shell & tube mean less cost for materials, simpler fabrication, shorter delivery lead times, easier installation, simpler support structures and vastly smaller footprints, especially considering dead space required to pull the tube bundle for cleaning.
