Plate and Shell Design

The APV Plate-and-Shell Heat Exchanger is constructed with the plates in a stack, surrounded by an outer shell enclosing the plate pack. The product plates are welded together in pairs with the service medium then circulated through the outer case and between the plate pairs. The end cap can be fully-welded or manufactured so that it can be opened for inspection. The service medium is routed through individual passes via a baffle plate similar to the shell in the tubular type of heat exchanger.

Compared with the normal plate-and-frame heat exchanger, the plate-and-shell type has the advantage of a higher working pressure limit (up to 70 bar) and working temperatures up to 350°C, and yet it has the compactness of the plate system.

Typical applications have been water/refrigerants cooling and water/water heating and cooling.

Product range

• Three models giving flow rates from 100 to 850,000 kg/hour.
• Operation at high temperatures to 350°C, and with extremes of temperature fluctuation.
• High pressures to 70 bar.
• Surface areas to 500 m2.
• No gaskets - plate-and-shells are virtually maintenance free.
• Space saving - uses only a third of the space required by a traditional tubular exchanger.

Features/benefits

• Choice of materials to suit application: Plate are available in stainless steel, titanium, or other alloys; the shell in carbon steel, stainless steel or titanium.
• Choice of size to match required throughput: PSHE2, PSHE3, PSHE5 & PSHE9 (300, 500 & 900 mm diameter plates), from 20 to 600 plates.
• Compact: offers considerable reductions in size and weight compared with shell and tube heat exchangers.
• Thermal efficiency: significantly higher levels of heat transfer than shell and tube heat exchangers.
• The shell can, optionally, have a removable end flange to facilitate shell-side cleaning.
• Computer design optimizes parameters of flow rate, inlet and outlet temperatures with other key parameters.
