Used Dynamometers For Sale

Contact Froude For Used Equipment Availability

Why Buy a Used Dyno?

We often will take a used dynamometer absorption unit in trade as part of a new system order. Sometimes we will acquire a used dyno from salvage, at a close-out auction, or even by donation. If possible, these absorption units are refurbished and offered for resale, individually, or with a new data acquisition and control system.

Many times a refurbished dyno is comparable to new, but at a much lower cost, and quicker delivery time. Also, Froude refurbished equipment carries a one-year warranty. 

Please review the available dynamometers and related equipment below and contact us for additional details.
