DYNAS3 HD - Heavy Duty

Heavy Duty Series - AC Dynamometer

The DYNAS3 HD series of heavy-duty dynamometers is intended for diesel engines. These machines feature extremely large torques, making them ideal for the output range that characterizes the medium and heavy diesel engines used in the commercial vehicle industry.

Segment: Automotive
Division: Mechatronics
Manufacturing Company: HORIBA Europe GmbH
Base product: DYNAS3

The HD product family is available with various cooling concepts. Pure air cooling allows easy installation on low-power machines of the HD product range. The high power AC machines are equipped with water cooling as well as a radial fan.

The HD LC (Heavy Duty Liquid Cooled) series of loading units feature especially powerful torques. They benefit from low noise levels as a result of liquid cooling. In addition, they generate less heat in test rooms due to heat dissipation via the coolant.

Key features

  • Wide power range from 255 kW up to 1,000 kW for all kinds of heavy-duty test applications
  • Highest rated torques up to 5,150 Nm
  • Lower power dynamometers are air cooled for easy installation and upgrading of existing test cells
  • High power motors are equipped with a radial fan combined with water cooling
  • Liquid Cooled (LC) version with heat exchanger for better heat dissipation and for noise sensitive applications (NVH)
  • Measuring flange for highest torque measurement accuracy of real shaft torque
