Description

The W-ST Series Water Brake Engine Dyno is built for testing diesel engines in on-highway, construction, mining, power generation, and marine applications. With multiple power capabilities and operational speeds up to 4,000 rpm, the W-ST Series supports testing a broad variety of engines. Designed as the next-generation replacement for the legacy 45X Series, including models 46X06, 45X07, 45X08, 45X09, and 45X10. This trunnion-mounted, fixed-base water brake engine dynamometer is ideal for continuous-duty engine power verification, quality assurance, endurance testing, and certification.

  • Dyno Rating: Recommended operating conditions for tests up to 8 hours long.
  • Intermittent Rating: Available capacity for no more than 10% of the test time and 10 minutes per test whichever is shorter should be spent in the power range between dyno rating and intermittent rating.
  • Testing requirements more than 8 hours should be evaluated per application.
