When it comes to service dynamometers, the PT 401 K / W covers the complete spectrum, including all performance categories. Whether the PT 401 W (workshop version) or PT 401 K (mobile in van trailers), performance is key here.

With performance of 900 kW for the rapid test and 510 kW for a full-load curve, it can handle any engine and also achieves unrivalled precision, thanks to the inclusion of a torque measuring device in the drive train. This dynamometer provides all you need for the future. Given the ever-bigger agricultural machinery and related performance requirements, forward-looking businesses should look no further than EGGERS dynamometers.
