Why are we using 300 kW engines to do 60 kW of work? 🚛♻️
In a traditional Refuse Collection Vehicle (RCV), the math is broken. To get roughly 60 kW of hydraulic power for the compactor, you need a massive 300 kW diesel engine. Why? Because 80% of the energy is lost in thermal waste, mechanical transmission, and inefficient PTO systems.
At Hydro Puls, we’ve found the "Hydraulic Shortcut."
By using the HPDD v26 TRT, we achieve a verified 62.0% Fuel-to-Hydraulic efficiency.
-
Direct Conversion: Our pistons generate hydraulic pressure directly from carbon-free fuel.
-
No Oversizing: We don't need a 300 kW "buffer." We deliver high-torque hydraulic power on demand, exactly when the press needs it.
-
The Result: A cleaner, quieter, and lighter truck that does the same work with a fraction of the energy input.
Check out the Sankey comparison below to see how we eliminate the "Thermal Trap" and turn a 15% efficiency baseline into a 60% performance reality.
Practical impact? We replace a bulky, high-maintenance 300 kW diesel setup with a single 205 kW HPDD module and a hydraulic accumulator. Because the system only runs when work is being done, the energy savings are twofold: extreme efficiency during operation and zero waste during standby. It’s time to stop oversized engines from burning your margins
