Coolers

Tube and air-cooled heat exchangers

We produce complete and highly efficient cooling heat exchangers in accordance with customer standards and specifications, for one or two passes of liquid flow. They can be installed in either horizontal or vertical positions. These heat exchangers consist of a shell (cylindrical or rectangular) containing a tube bundle fixed into a tubesheet. The thermal expansion difference between the shell and the tubes can be compensated either by a thermal expansion compensator on the shell or by U-tubes (for clean fluids, where cleaning is difficult), which allow independent expansion.

Coolers are manufactured from a wide range of materials according to environmental conditions and media type. Designs may include fixed tubesheets, floating heads, or U-tubes. Additional components may include shell compensators, clad tubesheets, and various types of baffles to improve efficiency. We also supply individual cooler parts such as tube bundles (straight or U-tubes) with clad or overlaid tubesheets. Tube-to-tubesheet joints may be strength-welded, strength-expanded, or a combination of both. The cooler delivery includes complete accompanying documentation with all required certificates and test reports, including a pressure vessel passport.
