Our Services

Shell & Tube Exchangers

With more than 20,000 units delivered since 1961, Shell & Tube exchangers have been Southern’s core focus since the beginning. From small 4″ diameter units that could fit on a table top, to 350,000 pound behemoths – we’ve built them all. If you need thermal and mechanical design for a complete unit, a replacement bundle, repairs, or retubes, Southern has the expertise to help.

Design & Build

For complete turnkey design and build – Southern has the experience needed to ensure you get exactly what you need exactly how you need it. Our thermal design engineers are involved early in the quoting process – they can suggest a design even if all you have is some basic process information and desired metallurgy. They can also take an existing design and modify it while working to maintain existing connection points and footprint.

If you have a complex job that needs to be done in the field, Southern is ready to help. We offer a broad range of services, such as field retubes, weld repairs, tube plugging / pulling, field machining and more. The people we send are experts when it comes to shell & tube and air cooled heat exchangers.
