Are you looking for a small and powerful 28 VDC solid-state Ground Power Unit? Easy to manoeuvre and not space demanding neither in its mobile nor fixed version?
ITW Ground Power Units

Reliable ground power solutions for aviation operations
Fieldair is New Zealand’s sole distributor of ITW GSE equipment, supplying ITW Ground Power Units (GPUs) to aviation operators across New Zealand and the Pacific.
Designed to provide consistent, efficient power to aircraft on the ground, ITW GPUs are a proven solution for reducing fuel burn, supporting maintenance operations and improving turnaround efficiency. Fieldair works with operators to supply the right equipment, ensure correct installation and provide ongoing support where required.

What are ground power units (GPUs)?

Ground Power Units supply electrical power to aircraft while on the ground, removing the need to run onboard auxiliary power units (APUs) or engines.
This supports:
- Reduced fuel consumption
- Lower operating costs
- Reduced emissions and noise
- Improved safety during ground operations
GPUs are commonly used during maintenance, pre-flight preparation and at fixed or remote operational sites.

Fieldair supplies ITW Ground Power Units as New Zealand’s authorised distributor for ITW GSE equipment.

ITW GPUs are widely used across the aviation industry and are known for:
- Reliable, stable power output
- Durable construction suited to demanding environments
- Efficient operation across a range of aircraft types
- Proven performance in both fixed and mobile applications
We work with operators to ensure the selected unit is appropriate for their aircraft, operating environment and infrastructure.
Product Models
ITW GSE 1400 28 VDC GPU
ITW GSE 2400 Compact 400 Hz GPU
The ITW GSE 2400 Compact GPU is the market’s best choice for point-of-use 400 Hz solid-state ground power units (GPU). It is small and simple, reliable and robust.

Fieldair’s role extends beyond supply.
We support operators through:
Equipment selection
Identifying the right GPU based on aircraft type, usage and site requirements
Installation and integration
Ensuring equipment is installed and configured for safe, reliable operation
Ongoing support
Providing advice, servicing coordination and support over the life of the equipment
This ensures GPUs are not only fit for purpose, but continue to perform reliably in service.

Lease options
Fieldair also offers fully maintained lease options for ITW Ground Power Units, providing a practical alternative to upfront capital investment.
Leasing can support operators by:
- Reducing initial capital outlay
- Providing predictable operating costs
- Including ongoing technical support
- Ensuring access to replacement units if required
Fieldair currently supports a number of leased units across New Zealand, with technical support available 24/7.
Applications
ITW Ground Power Units are used across a range of aviation environments, including:
Aircraft maintenance and MRO facilities
Commercial and regional operations
Business aviation and private operators
Remote or infrastructure-limited locations
Whether supporting routine operations or specialised requirements, GPUs provide a consistent and efficient ground power solution.
Supporting aircraft maintenance and operations
Ground power forms an important part of Fieldair’s broader aviation capability, supporting both aircraft maintenance and day-to-day operations.
