The new Tronair 90 kVA diesel ground power unit 11-4290-0000 remains ahead of the curve with the latest EPA Tier 4 Final emissions compliant diesel engine. This GPU is designed to serve as a 90 kVA 400Hz AC & 28V DC power source for parked aircraft.

The second output is available providing 28.5V DC power up to 600 amps continuous for aircraft servicing and 2,000 amps peak for starting.

The award-winning Doosan diesel engine with industry leading three-year warranty has electronic controls for more precise control over engine performance. This GPU requires no diesel particulate filter, reducing maintenance interval requirements and improving fuel economy.

SCR regulation and RC circuit ripple filtration ensure a finely tuned unit cable of operating with the most sensitive of aircraft. A large Murphy Digital Controller/Display allows the operator to monitor engine parameters in addition to fault codes. An aircraft end cable interlock circuit alerts the operator to a poorly connected cable. End of cable voltage sensing and output voltage drop compensation ensures full power is provided to the aircraft. A large 35-gallon fuel tank allows for 8 or more hours of run time at the rated load.

John was great to work with! There were some hold ups from the manufacturer when receiving our GPU but, John was always in communication with me and updating me on the status of the shipment date. Even after we had received the GPU which, was damaged from UPS, he did everything to again contact the manufacturer and get quotes for the damaged parts. The GPU itself has worked great and other than the damaged fender we are happy with what we've received!
