Aircraft Ground Power Unit (GPU)

Hydraulics International, Inc. is one of the world’s leading manufacturers of both military and commercial aircraft ground support equipment (GSE).  (HII) has over 40 years history of cutting edge aircraft ground support equipment (GSE) ingenuity  and new product technology innovation in three main business units:

1) Defense/Aviation/Commercial Ground and Engineering Support Equipment Systems (GSE).

2) Pneumatic Driven Liquid Pumps / Pneumatic & Electric Driven Gas Boosters / Air Amplifier Systems / Pneumatic & Electric Driven Nitrogen & Oxygen & Hydrogen & Helium & Argon & Carbon Dioxide & Mixed Gas Systems / Hydrostatic Test Pumps / High Pressure Components & Valves

                                                                                               3) Flow Metering / Analyzing / Totalizing Systems.

Hydraulics International, Inc. designs and manufactures 60 KVA & 90KVA diesel generated AC 400HZ and 28 VDC power units built for rugged military demand and environment with high performance. The system configuration is based on the most reliable and suitable state-of- the-art touch panel control and monitor technology with ease of operation and diagnostics in mind. The system is easy to operate, intuitive with an interactive data display and requires very low maintenance. The HII GPU provides the user with required maintenance power, automated built-in and diagnostic test features. The Cummins QSB 4.5, 165 HP, Tier III engine is quiet and efficient combined with a 400HZ generator with superior regulation.
