Shell & Plate Welded Plate Heat Exchangers


Heat Exchanger Description & Types

The two basic components of the Tranter Shell & Plate Welded Plate Heat Exchanger are the plate pack and the shell. Plate pairs are perimeter-welded together around both ports to form a cassette. Plate cassettes are then circumference-welded to each other to comprise a plate pack. End plates are perimeter-welded to the first and last cassettes. The first end plate has ports to which the inlet and outlet tubes are welded; the last end plate is blind. 
A flow director is inserted between a pair of longitudinal guide bars welded to the plate pack 90° from the inlet and from the outlet ports. These two diverters force the shell side flow to enter the plate pack channels instead of short-circuiting around the perimeter of the plate pack. Most exchangers are welded to a saddle frame for ease of handling and installation.

Configurations - Shell & Plate Heat Exchanger

The Welded Shell & Plate Heat Exchanger is available in 5 sizes.

The Standard Shell & Plate Heat Exchanger constitutes a welded pressure vessel of high integrity. The standard unit is not designed for access or cleaning by mechanical means.
The Removable Core Shell & Plate Heat Exchanger (available as an option in all sizes) is fully accessible for inspection and/or mechanical cleaning by removing the cover plate assembly. A full-face, flat-flange gasket is installed between the plate pack assembly cover and the shell assembly flange.
The Two-In-One Shell & Plate has two separate plate packs that share one shell. These cores can handle different or identical fluids. For flows that require a high flow rate and a short residence time (low hold-up volume), dual inlets and outlets can be piped together by means of special manifold options.
The Multipass Shell & Plate offers multiple passes through separate plate pack zones on both the plate and shell sides, with countercurrent flow through both passes. The unit has two plate pack units separated by a special one-port divider plate that directs the flow from the first pack into the second and changes its direction by 180°. Inlet and outlet ports are at opposite ends of the unit. The shell includes a special flow director that directs the shell-side flow through one plate pack and then the other.
