Calorimeter Test Stands

A calorimeter is a special purpose wind tunnel for testing thermal and flow characteristics of air-cooled heat exchangers such as automotive radiators, charge air and industrial machine coolers.

  • Customized to test your product and your test procedure.
  • Test over a wide range of performance conditions.
  • Reliable and robust with a low life-cycle cost.
  • Precise instrumentation provides accurate, repeatable results.
  • Test a variety of products including radiators, heat exchangers, and other flow devices.
  • Closable nozzles for high flow turn-down.

Whether you are looking for an upgrade of existing facilities or considering a new project, Emprise can work with you to go from concept, to design, to turnkey installation of your new test facility. Let Emprise show you how to make the testing of your product a breeze.
