The Hitzinger 400Hz Jet-Power Ground Power unit, was designed in conjunction with the military, offering the most compact solution to suit smaller loads of 30-60kVA. The design philosophy for the entire range of aviation equipment continues within our Jet-Power solution, providing minimal operating costs, reduced weight, smallest physical dimensions and designed to be extremely robust to ensure peak performance even in the more harsh conditions.

To minimise the weight and dimensions of the Jet-Power, a 2000rpm provides significant advantages including low fuel consumption, less maintenance and reduced running noise. Together with all these benefits, the Hitzinger diesel driven GPU provides improved emissions with engines up to a Tier4/COMMs4 standard.

Technical highlights

Hitzinger's design philosophy ensures that our 400Hz Ground Power Units for airport ground power systems are characterised by their lowest total cost of ownership, increased operational efficiency and low maintenance design.

The Jet-Power specifically offers additional space saving advantages and has proven to be an extremely compact solution for smaller loads <60kVA. The front vertical access door ensures ease of servicing throughout the entire unit and reduces maintenance times, coupled with the user friendly interface and touch screen display, explains why our 400Hz GPU's are market leaders.
