Dunn Heat Exchangers, Inc. is your one-stop shop for all your heat exchanger needs. In addition to our expert cleaning and repair capabilities, our Engineering Services department provides thermal and mechanical design, drafting, price estimates, and purchasing of materials.

Thermal Design

  • Dunn Heat Exchangers provides a thermal design, which is rendered using Heat Transfer Research, Inc. (HTRI) to achieve an optimum design. This method provides the most suitable exchanger technology with maximum reliability and efficiency, at a minimum cost.
  • All exchangers are designed in accordance to the Tubular Exchanger Manufacturers Association (TEMA) designation of heat exchangers including shell and U-tube exchangers for single phase, multi-phase and multi-component condensers (horizontal, vertical, and reflux) and reboilers (kettle, thermo siphon, and falling film).
  • Dunn's experienced engineering team can also provide troubleshooting to analyze exchanger performance issues and propose practical solutions to restore or enhance function.

“Our capable Engineering Services department provides you with thermal and mechanical designs, drafting, price estimates, and purchasing of materials.”
