Harrison Hydra-Gen

Summer heat doesn't stop emergency response, and neither should your power system.

hPower helps ambulances stay powered and cool whether the engine is running or not. By reducing unnecessary idle time, crews can maintain climate control and operate critical onboard systems while lowering fuel consumption, emissions, and engine wear.

Reliable power. Greater comfort. Smarter idle mitigation.

Power should be part of your equipment, not something you have to add on and manage separately.

Harrison Hydra-Gen PTO and hydraulic generators are built directly into your system, delivering reliable power without the need for extra machines, fuel sources, or setup time.

When power is built in, operations run cleaner, faster, and more efficiently from start to finish.

Hands-on training for a brand-new hPower unit.

Brian Goldberg and Azael Garcia spent time with the Keller team walking through their new unit and helping make sure they are ready to get the most out of hPower in the field.

With dependable onboard power built right into the vehicle, their crew can stay prepared without relying on a separate portable generator. hPower gives teams the flexibility to run essential equipment with the engine on or off, helping reduce idle time, lower fuel use, and limit unnecessary wear on the vehicle.

Excited to see this unit hit the road and thank you to the Keller Public Safety team for having us out there!

Maximum power. Minimal footprint.

Harrison Hydra-Gen hydraulic generators deliver high-quality AC power by transferring horsepower from your main engine through hydraulics—no secondary gas engine required. That means no added emissions, fewer components, and fewer common failure points in the field.

Designed to be mounted out of sight and out of mind, these systems keep your setup clean while still providing reliable, on-demand power. With multiple AC voltage options and flexible mounting capabilities, they are built to adapt to the way you work across industries like construction, fire and emergency, oil and gas, and more.

This Memorial weekend, we honor and remember the brave men and women who made the ultimate sacrifice in service to our country. Their courage, dedication, and selflessness continue to inspire us every day.

At Harrison Hydra-Gen, we are proud to support the people and industries that help protect and serve our communities, including the military and emergency response teams who rely on dependable power in critical moments.

This weekend, we remember those who gave everything for our freedom.

New delivery highlight: Wilson County.

Wilson County's newest hPower-equipped unit is ready for service, giving crews access to reliable onboard power directly from the vehicle. With hPower, teams can run essential equipment with the engine off, helping reduce idle time, lower fuel use, and protect the vehicle's engine from unnecessary wear and tear.

The results are already adding up. On their current hPower-equipped units, Wilson County has reduced idling by about 50% and avoided an estimated 87,000 ghost miles that would have otherwise been added to their engines through idle time.

Now, they are adding another hPower unit to the fleet.

No separate portable generator. No extra setup. Just dependable mobile power when and where it is needed with the engine on or off.

Thank you to Wilson County ESD #4 for your business. We are excited to see the continued savings this new unit will deliver.
