Hitzinger’s vision of reduced running costs and emission have been realised with our latest generation of 400Hz Ground Power Units (GPU) and Airport Ground Power solutions. Using modern processing technologies, innovative materials and ingenious engineering, the Hitzinger Ground Power Units can supply power ranges between 30-180kVA with multiple options possible to meet your exact requirements.

Using the lowest speed engine of any GPU, we can provide the lowest total cost of ownership with massive fuel savings available from reduce fuel consumption and high alternator efficiency. Together with significant running cost savings, our 400Hz Ground Power units (GPU) reduce the maintenance requirements and running noise, together with the use of engines up to a Tier4/COMMs4 standard providing lower emissions.

Technical highlights

The D POWER is characterised by its extremely low running costs when running at the lowest speed of 1500rpm. This provides not only lower fuel cost through optimised usage, but lower noise, better maintenance from less engine stress, better reliability and increased efficiency.

Maximum serviceability
The modular arrangement of the switchgear simplifies all service work. Large-size side flaps provide optimum access.

Simplified user operation
Our patented ACON Control unit is designed to provide ease of operation together with a simplistic navigation system.
