DT843 Dynamometer

General View

The newly patented Dyno Tech DT843 dynamometer provides agricultural dealerships the capability to load test 800 horsepower@1000 rpm, this, along with an impressive rated torque capacity of 4300 lb/ft.

This new dynamometer uses the innovation of a single rotor tube absorption unit, providing smooth dynamic operation during high horsepower test sessions. Combining smooth dynamic rotor operation along with equalized internal torque loading makes this new design superior to previous prony brakes which require multiple connected rotors.

With it’s patented design, the DT843 boasts a 20%+ increase in internal cooling efficiency. Direct cooling at the point of internal friction, combined with a 275 gallon supplemental cooling reservoir provides maximum dynamic high horsepower test sessions. During high torque load testing, it’s mass, provided by the supplemental water reservoir,  provides maximum stability during dynamic operations.

Exclusive Features

  • Single rotor absorption unit dramatically reduces the number of mechanical components which allows smooth dynamic operation.
  • Improved dynamic water sealing reducing long term performance issues.
  • Non-invasive service of drum, maintenance is performed externally.
  • Extended maintenance intervals due to advances in brake design and lubrication technology.
  • Large supplemental cooling reservoir with direct cooling at the point of friction provides maximum test sessions.
  • Extended dynamometer shaft provides compensation for through wall operation, as well as additional operator safety during pto hookup.
  • Ease of control and operation from the rear of the dynamometer increasing operator comfort and safety.
  • Unsurpassed product warranty, provided at your request prior to purchase.
  • Automatic water temperature shut down and reset.
  • Onboard absorption unit diagnostics using the Power Pro 1000.
