🛠️ Dyno Tech DT843: Power, Precision, and Patented Innovation
The newly patented DT843 dynamometer sets a new benchmark in agricultural power testing—delivering the ability to load test up to 800 horsepower @ 1000 RPM with an outstanding 4300 lb/ft torque capacity.
🔧 Engineered Excellence
At the heart of the DT843 is a single rotor tube absorption unit, a patented design that ensures:
- Smooth dynamic operation during high-horsepower testing
- Equalized internal torque loading, eliminating the inconsistencies found in multi-rotor Prony brake systems
❄️ Advanced Cooling Efficiency
With direct cooling at the point of kinetic friction and a 275-gallon supplemental reservoir, the DT843 delivers:
- Over 20% improvement in internal cooling performance
- Extended high-power test sessions without thermal saturation
- Structural mass stability for torque rise testing and dynamic load scenarios
Dyno Tech is proud to offer the DT843—the first of its kind to combine power, precision, and durability in one patented package. It’s built not just for today’s testing needs, but to meet the future of ag tractor performance head-on.
