Tronair 11-6644C1010 Towable Gas 28V DC Aircraft Ground Power Unit (GPU)

This 28V DC gas-powered GPU is designed for a broad range of fixed-wing and rotary aircraft that require reliable ground power for starting, servicing, or maintenance. Its compatibility makes it a versatile choice for commercial, military, and business aviation operations. Always consult your aircraft’s maintenance manual to verify compatibility with 28V DC ground power systems.

Gas-powered GPUs like the 11-6644C1010 are ideal for remote or ramp operations where access to grid power is limited. They provide high mobility and independence, which is especially important in FBOs, military flight lines, or regional airports. Electric GPUs are quieter and often preferred indoors, but gas units excel in flexibility and rugged outdoor performance.

This unit runs on standard unleaded gasoline, making it convenient to refuel in most locations without requiring special aviation fuels. The fuel tank is sized for extended operation on the ramp. Operators should always follow Tronair’s recommendations for clean, fresh fuel to maintain engine performance and reduce maintenance needs.

The GPU is designed with heavy-duty wheels and a durable tow handle, allowing easy maneuvering around ramps, hangars, or flight lines. Its compact footprint ensures it can be positioned close to aircraft without blocking service areas. This portability makes it especially useful in busy environments where space and time efficiency matter.

Multiple design choices address safety, including automatic circuit protection, voltage regulation, and engine safeguards. Emergency stop controls provide rapid shutdown in case of abnormal operation. These protections help prevent equipment damage and ensure operator safety during high-demand ground servicing.

Yes, Tronair designed the 11-6644C1010 with voltage regulation to protect modern aircraft avionics from surges or irregular output. Stable 28V DC output ensures that onboard systems can be powered safely during preflight checks, maintenance, or extended ground operations. This makes it a trusted choice for both commercial and business aircraft.

Routine maintenance includes periodic oil changes, air filter replacement, and inspection of electrical connections. Tronair recommends following a schedule similar to that of other small industrial engines, typically every 100 operating hours or annually. Keeping up with maintenance ensures reliable output and maximizes the unit’s service life.

While technically possible, gas-powered GPUs are not recommended for indoor use due to exhaust emissions. For hangar operations, Tronair’s electric GPUs are a better fit. The 11-6644C1010 is best-suited for outdoor ramp environments where ventilation is not an issue.

The GPU comes standard with large pneumatic tires that handle uneven ramp surfaces and rough outdoor conditions. A tow handle and balanced design allow a single technician to maneuver the unit safely. These mobility features ensure it remains practical and efficient in real-world ground support operations.

Yes, the “C” designation in the model number indicates that the unit is CE-marked and meets European safety and performance standards. This ensures the GPU is approved for international operations and adheres to strict compliance requirements.

The 11-6644C1010 features both high-pressure and low-pressure regulators, giving operators more precise control over output levels. This flexibility allows servicing of a variety of aircraft systems without the risk of overpressurization. It also reduces wear on onboard components by delivering only the necessary power.

Yes, the design supports short-distance towing on ramps or flight lines. The towbar and heavy-duty construction make it possible to reposition the unit quickly with small utility vehicles. However, Tronair advises keeping speeds low to prevent damage to the GPU or its wheels.
