View DetailsIn the highly complex grid of modern airports and maintenance hangars, flight readiness depends heavily on the performance of ground support infrastructure. An Aircraft Ground Power Unit (GPU) serves as the primary system that supplies clean, electrical energy to an aircraft while parked on the tarmac. By delivering 400Hz AC or 28.5V DC output, GPUs allow pilots and maintenance crews to run flight controls, navigation systems, and on-board electronics without running the aircraft’s fuel-thirsty and emissions-heavy Auxiliary Power Units (APUs).
This ground-level electrical support is crucial not only for saving fuel but also for meeting modern environmental targets. As airports push toward carbon neutrality, the shift from traditional diesel engine-driven generators to solid-state (frequency converter) and battery-powered towable GPUs has accelerated. Ground service providers rely on these advanced power systems to handle the demanding electrical needs of next-generation aircraft like the Boeing 787 and Airbus A350, both of which require robust, regulated power during turnarounds.
Aviation ground operations rely on a wide range of specialized GSE. We manufacture and supply equipment across key categories to keep operations running smoothly:
CD5207GJJ, CD5580GJJ, CD5341GJJ: Aircraft refueling trucks featuring high-capacity pumps, advanced filtration systems, precise metering, self-circulation, and dual pressure control valves. Designed for safe, efficient underwing and overwing fuel operations.
Slave & Castle Dollies: Designed for rapid pallet transit across busy tarmacs. High-tensile steel frames with multi-directional roller decks, secure locking pins, and heavy-duty braking assemblies ensure safe cargo handling.
GPU, PCA, & Cabin Heaters: Energy storage towable GPUs, 90KVA aircraft ground static power, PCA Unit - CD190, and aircraft cabin heaters provide reliable ground electricity and temperature control to parked aircraft.
The ground power industry is moving through a major technological shift. Historically, airports relied on diesel engine-driven generator sets (rotary GPUs) to produce the required 400Hz frequency. While effective, these systems produce high emission levels, require heavy maintenance, and run at relatively low energy efficiency. Today, the industry is transitioning toward two modern technical pathways:
These units connect directly to the airport’s local grid, taking 50Hz or 60Hz utility power and converting it into highly stable 400Hz aviation power using advanced power electronics. With no moving parts, solid-state converters achieve efficiencies over 95%, reduce maintenance costs, and run virtually silent on the apron.
Battery-based GPUs represent the zero-emission future of ground operations. Equipped with heavy-duty Lithium Iron Phosphate (LiFePO4) battery packs, these mobile units can power multiple aircraft turnarounds on a single charge. When charged from renewable energy sources, they enable completely carbon-free ground operations.
Modern GPUs now feature integrated IoT sensors that monitor power quality, battery health, and plug-in status in real time. This data feeds back to central airport fleet management systems, allowing ground crews to predict maintenance needs and avoid gate delays.
Aviation ground support equipment must perform reliably in diverse and challenging environments. Our custom GPUs and GSE are engineered to operate in extreme conditions globally:
In regions like Scandinavia and Northern Canada, equipment must operate in temperatures down to -40°C. Our units feature insulated battery systems, critical component pre-heaters, and specialized hydraulic fluids to ensure reliable start-ups and deicing runs in heavy snow.
In regions like the Middle East, ground equipment faces ambient temperatures over 50°C and fine dust. We build our units with heavy-duty cooling loops, dust-tight IP65 enclosures, and multi-stage filtration to protect electrical components from overheating and dust ingress.
Coastal and tropical airports present high humidity and salt spray, which can accelerate corrosion. We use hot-dip galvanized steel frames, stainless steel fasteners, and marine-grade epoxy coatings to extend the service life of our dollies, stairs, and service trucks.
Our manufacturing base in China delivers significant efficiency and cost benefits for global airports and ground handlers. By working within a highly integrated industrial cluster, we secure high-grade raw steel, advanced hydraulics, and premium electrical systems quickly and reliably.
This mature supply chain ecosystem allows us to reduce production lead times while maintaining strict quality control. Combined with precision robotic welding, automated testing bays, and large-scale manufacturing, we deliver durable, high-performance GSE at competitive prices. Every step of our manufacturing process—from initial steel fabrication to final electrical checks—is carefully managed to meet global delivery schedules.
We leverage advanced design, engineering, and continuous R&D innovation to build efficient, state-of-the-art ground support equipment.

Compliance with international aviation standards is non-negotiable for airport ramp operations. Every GPU, PCA unit, and passenger stair we build undergoes a rigorous testing program to ensure safe operation alongside multi-million dollar aircraft. Our manufacturing processes and products align with key international standards:
Our equipment complies with the IATA Airport Handling Manual (AHM), specifically safety protocols AHM 910, 913, and 915. These guidelines ensure our designs integrate safely with ramp personnel and airport operations.
Our 400Hz converters and GPUs are engineered to meet ISO 6858 and SAE ARP 5015 standards. This guarantees stable voltage regulation, low harmonic distortion (THD < 2%), and reliable power delivery without voltage spikes.
From initial design to final load-bank testing, our facilities operate under an ISO 9001 certified quality management system. This ensures traceabilty for all materials, structural components, and critical electrical sub-systems.
We provide flexible, customer-focused OEM and ODM services to adapt our products to your specific fleet operations. From custom branding and color schemes to specialized electrical configurations and structural modifications, we manage the process from design through to after-sales support.
