Feature
The exchanger in 3D, as you design it.
Dimensions, pass arrangements, and nozzle orientations show in the model as soon as you change them.
Interactive model
The reference exchanger, in your browser.
HX-123, the reference exchanger: TEMA type AET, a 40 in shell, and 554 tubes. You can turn it, open it up, and look inside.

The model, the component tree, and the timeline.
In PlutoHX the 3D view sits beside a component tree that lists the objects of the design with their attributes. The model can be seen in perspective, as an x-ray or exploded, and an assembly sequence timeline plays the build step by step.
About this viewer
An illustration, drawn from the reference dimensions.
The model on this page is generated from the dimensions of the reference exchanger and drawn in the CAD line style of the other drawings on this site. It is an illustration of HX-123, not a design output.
Colors follow the convention used across PlutoHX material: tube side nozzles in mint, shell side nozzles in blue, and the tubes in copper.
The same exchanger, stage by stage
The fabrication sequence shows how this exchanger is built, from the front end to the saddles.
Coming Winter 2026
We would be glad to show you PlutoHX.
PlutoHX launches at the end of this year. A live demo shows how it fits the way your team works.
Visit us at the booth for a deep dive into PlutoHX.
