Customer Services - Older Dynamometers

Does Your Older Froude Equipment Need Service or Parts?

Froude dynamometers are built for durability, as evidenced by the fact that many have been operating for over 50 years. The dynamometers listed below are no longer available built new. However, our Customer Service Team may still be able to refurbish these dynamometers, or be able to supply them as second-hand machines “As New.”

We also have power curves, spares, and manuals* for most, if not all of the dynamometers listed here. Please click on the PDF icons in the far right-hand column in the table below to view the Specification documentation or Power and Torque Capacity diagrams for some of our older dynamometers.

* Manuals may be purchased via Customer Service - please use the Request Information tab below. 

If you don't see the dynamometer you are looking for in the table here, please use the Customer Service tab at the bottom of this page to request the information.

Our range of Wet and Air Gap machines have a wide range of uses and, being built for durability, some of our earliest dynamometers are still in use over 50 years later.


The Specifications supplied for the listed dynamometers are based on the standard versions.

If you believe that you have a “Special” version of a dynamometer type, please use the Request Information tab to contact us, ensuring to include all details from the dynamometer nameplate, so that we can trace the specific curve used in the original build of your machine.
