The tube bundle is the heart of your shell and tube heat exchanger, and when it fails, your whole process slows down with it. At KAM Thermal Equipment, we manufacture exact-match replacement tube bundles for virtually any shell and tube unit, including obsolete equipment and bundles originally built by other manufacturers. Made in the USA, engineered to spec, and built to get your operation back online fast.
A tube bundle is the removable core of a shell and tube heat exchanger, the assembly of tubes, tubesheets, baffles, and support structures where heat transfer actually happens. Over time, tubes corrode, foul, crack, or perforate, and the bundle can no longer perform. Rather than compromising on efficiency or risking an unplanned failure, replacing the bundle restores your exchanger to full performance.
We build each replacement bundle to match your unit’s exact specifications: tube count, diameter, length, pitch, material, pass arrangement, and baffle configuration. The result drops into your existing shell and performs like the day the exchanger was new, or better.
Here’s what sets KAM Thermal apart: you don’t need the original manufacturer to still be in business. We maintain a comprehensive database that allows us to cross-reference and duplicate tube bundles originally fabricated by other manufacturers, even when the OEM is long gone or the documentation is lost.
If you have an aging, discontinued, or undocumented heat exchanger, we can reverse-engineer and reproduce the bundle so you can keep the equipment you already own running, without replacing the entire system. This is one of the most cost-effective ways to extend the life of legacy industrial equipment.
Not every failing exchanger needs the same solution. Here’s how the options compare, andwhere a replacement bundle makes the most sense.
| Option | Best For | Consideration |
|---|---|---|
| Tube plugging | Minor, localized leaks (typically under ~10% of tubes) | Fast stopgap, but reduces capacity and doesn’t address systemic wear |
| Retubing | Tubes worn but tubesheets, baffles, and shell still sound | Reuses the existing frame; not viable if support structures are corroded |
| Full bundle replacement | Widespread corrosion, damaged baffles/tubesheets, or an obsolete design | Restores full performance and lets you upgrade materials or design |
An honest note: KAM Thermal does not perform on-site repairs. Because heat exchangers endure intense heat, pressure, and corrosive service, a bundle that has reached the end of its life is often safer and more economical to replace than to patch. When tubesheets, baffles, or the shell show systemic wear, a new bundle built to current standards is the reliable long-term fix, and frequently the better value over the life of the equipment.
Yes. We maintain a comprehensive database that lets us cross-reference and duplicate tube bundles originally built by other manufacturers, including obsolete and undocumented units. You do not need the original manufacturer to still be in business.
We do not perform repairs. We manufacture exact-match replacement bundles and replacement heat exchangers. Because of the wear and tear from intense operating conditions, it is often safer and more cost-effective to replace a failing bundle than to repair it.
Retubing can work when the tubes are worn but the tubesheets, baffles, and shell remain sound. If there is widespread corrosion, damaged support structures, or an obsolete design, a full replacement bundle built to current standards is the more reliable solution.
Ideally the original specifications or drawings, but we can also work from the exchanger’s nameplate data and physical dimensions to reverse-engineer an exact-match bundle, including tube count, diameter, length, pitch, material, pass arrangement, and baffle layout.
We offer material flexibility for harsh conditions, including stainless steel, copper-nickel, and specialty alloys, so the replacement is matched to your specific service environment.
