Schenk water brake dynamometers

Water-brake dynamometers are mainly used as loading units for production testing of combustion engines (primarily diesel engines) on engine test stands. They are also used as loading units for powertrain and gearbox test stands, as well as chassis dynos.

Features

The water brake dynamometers type D are known for the following features:

• High measuring accuracy
  
• Simple construction
  
• Robust design
  
• High-quality materials (water bearing parts: sea-water resistant!)
  
• Reliable operation even in case of not optimal cooling water conditions
  
• Wide range of standard sizes for different engine power
  
• Many variants for a great variety of applications
  
• Excellent ratio between price and power (USD/kW)
  
• High power density
  
• Compact construction for low requirement of space
  
• Low power requirement
  
• No remarkable reactive current
  
• Extensive accessories, also for their adjustment to different cooling water supplies
