In the demanding world of aviation, efficient ground support equipment is essential for seamless operations. One critical component in this setup is the Ground Power Unit (GPU)—a machine designed to supply power to aircraft while on the ground. Among the various types available, the 28V GPU Diesel stands out for its versatility, durability, and suitability for small to medium-sized aircraft and helicopters. If you’re searching for reliable, high-performance diesel GPUs, this blog will help you understand their benefits and what makes the JTL series 28V GPU Diesel units a preferred choice since 2003.
What Is a 28V GPU Diesel?
A 28V GPU Diesel is an engine-driven ground power unit that supplies 28.5 volts of DC (Direct Current) to aircraft parked on the tarmac. This voltage is essential for powering avionics, lighting systems, onboard electronics, and air-conditioning systems during pre-flight checks, maintenance, or passenger boarding. These units are typically used with smaller commercial planes, private jets, helicopters, and military aircraft.
Diesel-powered GPUs are known for their portability and ability to function in remote locations where plug-in AC power may not be available. This makes them indispensable for both large airport hubs and off-site aviation maintenance centers.
Why Choose a Diesel-Powered 28V GPU?
1. Portability and Flexibility
One of the biggest advantages of diesel GPUs is mobility. Since they are engine-driven, they can be used in any location without depending on a fixed power infrastructure. This makes them ideal for regional airstrips, military bases, and temporary aviation operations.
2. Fuel Efficiency
Diesel engines are known for their higher fuel efficiency compared to gasoline engines. A well-engineered 28V diesel GPU can run for hours on a single tank, reducing the need for frequent refueling and lowering operational costs over time.
3. High Reliability and Durability
Engineered to work under harsh conditions, 28V GPU diesel units are built for rugged use. Whether in scorching deserts or icy runways, they provide consistent power, helping avoid costly delays and downtime.
4. Low Maintenance
With robust engineering and quality components, modern diesel GPUs require minimal maintenance. JTL series GPUs, for example, are designed for long service life with easy-to-access parts for routine service.

Typical Applications of 28V GPU Diesel Units
✈️ Aircraft Maintenance and Repair
Technicians need constant, reliable power to test aircraft systems, troubleshoot avionics, and carry out repairs. A 28V diesel GPU ensures that the aircraft’s batteries are not depleted during such activities.
🛫 Pre-Flight and Post-Flight Checks
From powering cockpit systems to running cabin lights and air conditioning, ground power units support many of the systems needed during boarding or deplaning.
🛩️ Remote or Temporary Airfields
Military missions, medical evacuations, or exploratory missions often involve remote landing sites. The portability of diesel GPUs like the JTL 28.5V unit makes them perfect for such scenarios.
🔧 Aircraft Assembly and Testing
Aircraft manufacturers use GPUs to supply power during testing and assembly stages. A high-quality diesel GPU ensures consistency and safety during these sensitive procedures.
Environmental and Safety Considerations
Modern diesel GPUs, including JTL models, are designed with environmental and safety standards in mind.
✅ Emission Control
Advanced engine designs meet stringent emission regulations while maintaining performance.
✅ Noise Reduction
Improved insulation and quieter diesel engines reduce noise pollution, a key requirement at busy airports or military installations.
✅ Automatic Shutdown Features
To prevent overheating or voltage fluctuations, most units come with built-in safety mechanisms like auto-shutdown for low oil pressure or high engine temperature.
How to Choose the Right 28V Diesel GPU?
When selecting a 28V GPU Diesel, consider the following factors:
✅ Aircraft Compatibility
Ensure the GPU’s voltage and amperage match your aircraft’s requirements. Over-voltage or insufficient amperage can damage systems or cause malfunctions.
✅ Mobility Requirements
If you’re operating in remote areas or across large airports, look for a model with rugged wheels, tow bars, or forklift pockets.
✅ Engine Quality
Opt for models using reputed diesel engine brands known for reliability and easy serviceability.
✅ Support and Service
Choose a manufacturer or distributor that offers spare parts, maintenance training, and 24/7 technical support.
