Part Number Index

Every SWEP frame in the range, with the part numbers we hold data for beneath it. If you have a string and want it decoded, or a duty and want a frame, the fastest route is to call.

Index

The index below is organized by frame. Each frame page carries its specifications, the configurations we have on file, and the duty it suits.

Part numbers are configured rather than catalogued - the same frame appears in many plate counts, pass arrangements, materials and connection sets. The string is the specification.

Configured Part Numbernoun

A designation assembled from choices instead of taken from a list: frame, plate type, plate count, pass arrangement, material, pressure class and connections, written in a fixed order. Change any one field and it describes a different exchanger.

Series Index by Flow Band

Every SWEP series on this site, grouped by the maximum flow of its frame. The count beside a series is the number of catalogued designations with a page of their own; they are listed under Part Numbers on the series page.

How configured part numbers differ from a catalogue

A frame such as the B25T exists in many plate counts, several pass arrangements, four or five material combinations and a range of connection types. Each combination is a distinct orderable string, and the total is far larger than any list a distributor would publish.

That means searching for an exact string rarely succeeds unless someone has stocked that exact build. Searching for the frame and then specifying the rest is the reliable route.

It also means an existing unit's string is worth keeping. It encodes decisions - pass arrangement, material, pressure class - that someone made deliberately, and reproducing them is easier than rediscovering why.

Part Number Index: Questions From the Field

Model and size first, then plate type, then x and the plate count, a slash and the pass arrangement, the material code, the pressure class, and last the connections in port order. B25THx30/1P-SC-M 16+22U+2x1"NPT reads as a B25T frame with H plates, 30 of them, single pass, 316/316L stainless with copper braze, M pressure class, followed by four connections.

Knowing the order lets you check a string someone has copied by hand: a missing field is obvious once you know what should be there. The Model Number Guide takes each field in turn.

Both. The article number identifies one specific build and is the quickest match when it is on record. The designation is the one a person can read and verify, and it still works when the article number is not.

If only one survives, either is a starting point. A photograph of the whole nameplate beats a transcription, because it also captures the stamped pressure and temperature limits and any approval marks, none of which are in the string.

Dropping the trailing T is the first. B25T and B25 are different plate generations and physically different plates, so the wrong one may not match the existing piping.

The second is reading AS as All-Stainless. In a model name such as B250AS it means AsyMatrix, an asymmetric channel plate. Copper-free construction is shown by the material code - SN or SPS - not by the model.

The third is treating the digit after the plate letter, as in H0 or M2, as a performance grade. It tracks port size and port centre distance.

Not directly. An equipment maker's part number is their stock code for whatever they bought, and it does not decode into a frame or plate count.

Go to the exchanger itself. Under the insulation there is normally a SWEP nameplate on the front cover plate with the designation. If it has been painted over or lost, send the equipment make and model, the refrigerant or fluids, and the measurements described in the next answer. That is enough to identify the frame and work out the rest.

Height and width of the plate pack, the thickness of the pack between the cover plates, and the centre-to-centre distance between ports both vertically and horizontally. Those identify the frame, and the thickness gives the plate count.

Then note each connection: thread, solder, flange or grooved, its size, and which face it is on. Add the fluids on each side, since they decide the material and pressure class, which no measurement will reveal. A copper-colored line at the plate edges shows copper braze; that is worth photographing too.

Some can. Connections can usually be changed to suit new piping. The material code can move, for example from SC to MC where the water has turned out to be chloride-bearing, with no thermal consequence worth worrying about.

Plate count, plate type and pass arrangement are different. Each one changes capacity and pressure drop, so the unit should be rated again at your conditions before the order is placed. Pressure class should only ever go up, and only where it is offered on that frame. Tell us what you want to change and why.
