Heavy-duty solutions engineered to optimize airside cargo and baggage logistics.
Modern airport networks are experiencing a structural shift toward green airfield electrification. The reliance on the aircraft’s onboard Auxiliary Power Unit (APU) during gate turnaround is no longer viable due to massive jet fuel consumption, excessive noise pollution, and stringent local environmental regulations. High-efficiency Portable Aircraft Ground Power Units (GPUs) serve as the cornerstone of this transition, delivering stable 400Hz AC or 28V DC electrical power directly from the ground system.
As a global Tier-1 wholesale aircraft GPU manufacturer, we engineer systems that optimize ground operations (GSO) through advanced power electronics. Ground Power Units are no longer simple mechanical generator sets; they are intelligent power hubs integrated into the smart airport grid. The primary driver for modern fleet procurement focuses on energy conversion rates, total cost of ownership (TCO) reduction, and system reliability under extreme climatic fluctuations.

Pre-Conditioned Air (PCA) units and mobile cabin heating units to maintain optimal temperature envelopes for passengers during boardings.
The core topology of ground power units is split between solid-state (static) frequency converters and diesel-driven rotary generators. Solid-state portable GPUs utilize advanced Insulated Gate Bipolar Transistors (IGBT) and Silicon Carbide (SiC) power switching circuits. By rectifying standard utility grid power (50/60 Hz) to DC and then converting it back to highly regulated 400Hz AC power, static units achieve up to 96% energy efficiency compared to the 35%-40% limits of internal combustion engines.
Decarbonization plans require the total exclusion of diesel generators on airfields. Our next-generation Energy Storage Ground Power Units operate entirely on lithium-iron-phosphate (LFP) chemistry battery blocks. By storing grid energy during off-peak times or integrating directly with airport solar photovoltaic networks, battery-powered GPUs eliminate zero tailpipe emissions and drop acoustic footprints below 60 dB(A) at 1 meter. This represents a significant reduction compared to legacy turbine or diesel GSE units.
Modern fleets require flexible support architectures. Standard narrow-body and wide-body commercial jets (e.g., Airbus A320neo, Boeing 737 Max, Boeing 787) rely heavily on 115/200V AC at 400Hz, while regional turboprops, helicopters, and private aviation require 28.5V DC supply lines. Our integrated portable dual-output systems dynamically regulate both circuits with automatic voltage compensation algorithms, preventing load-shedding and potential avionic faults.
Ground operations represent a complex logistical system where Ground Support Equipment (GSE) downtime can cause massive cascading delays. Ground Power Units must align with the specific operational realities of various ground-handling sectors:
For high-frequency commercial fleets, turnaround windows are compressed to 25-45 minutes. Portable GPUs must feature ergonomic cable deployment systems, simple control panels with multi-language HMI interfaces, and quick-connect grid couplings to ensure immediate power delivery upon engine shutdown.
MRO stations require continuous, clean power for deep system avionics diagnostics. In this scenario, static converters are preferred due to the total absence of exhaust fumes indoors, minimal maintenance requirements, and the capability to run at full load for 24-hour cycles without thermal fatigue.
Military operational profiles demand portability, low thermal visibility, and resistance to environmental stress. Our specialized military portable units are built to meet MIL-STD-810G standards, ensuring reliable operation in sub-zero arctic fields or sandstorm-prone desert forward operating bases.
