The result of 26 months of hard work in our development center -- this is the brand new R-series. Based on analyses of an enormous amount of data from applied metrology in diagnostic fields, as well as data from the sectors of development, manufacture and service of agricultural machines and equipment, we have produced the most modern dynamometer on the market.

“This robust instrument combines a maximum amount of technologies and precise engineering, with emphasis on, and respect to, the elementary principles and maintenance of reliability,” says František Humpolíček, ATX-dyno Technical Director & CTO. A combination of modern technologies and pure reliability

is the fundamental DNA of the R-series dynamometers.

“It was very important for us to develop the R-series dynamometers in close cooperation with specialists from the fields for which these instruments are intended. This allowed us to understand important details of their ongoing use in development and testing laboratories, and to design ergonomic devices and work environments of the highest standard, meeting the expectations of these specialists,” says Jakub Klobása, ATX-dyno CEO.

The future belongs to ATX-dyno dynamometers. Expert attention, precise workmanship and high quality are the basic attributes of this rising star.

Performance is top priority

A redesigned chassis has been reinforced and spatially optimized at critical points in order to capture longitudinal torsion from the extreme power outputs with which these dynamometers are able to work. These parts contain only components that meet the strictest requirements for quality and precise workmanship. The twisting movement is transmitted to the eddy-current absorbers via effective transmission with the highest possible efficiency. 


 Quiet cooling power

 When working with dynamometers, it is critical to remove any generated heat. Heat removal capacity is one of the main criteria for the usefulness of dynamometers. The optimal performance of the instrument is paramount, and can be indirectly influenced by unnecessary heat. Equally important, however, is that the dynamometer can maintain its high efficiency for as long as possible.

The two cooling circuits of the R-series are optimized by CFD methods and allow a remarkable extension of the duration of power-tests without using additional fluid or resistor cooling systems. (Over time, even good dynamometers have been stopped dead by poor fluid or resistor systems.)  


Smart design

The SW architecture, together with the electronic control features and ECU of the R-series dynamometers, make up the most evident necessities for correct collection, evaluation and interpretation of the test data. There is no room for a compromise, but you don’t need to. The smart control system is ready to do what you say. The dynamic and static modes provide everything you need for an individual approach to specific tests, all with maximum simplicity and intuitiveness.


Crafted to perfection

Perfection is in the details and the R-series dynamometers are perfect. We have included only the best components and craftsmanship in these instruments and this care is evident. Every element of these tools is accessible, intuitive to use, and exactly how you might design it yourself. You will always have precisely what you need, because everything is carefully integrated in the design, including 3 cardan sets, supporting foot, box for work and safety equipment, control elements, handling frame, fixtures, inspection windows and the like. External ducts may be attached to the cooling exhaust pipes to use the warm air for heating the premises or to lead the warm air outside, e.g. during work in a climatic chamber. 


 Do you work in a test laboratory? Or do you need to be mobile? We are ready to fulfil all your requirements and meet your needs. The R-series dynamometers allow any mounting - to a box chassis, utility vehicle or a pick-up.
