GB/GC range - Compact Mobile Ground Power Unit for General Aviation, Business Aviation & Regional Aircraft (Diesel Engine Driven)

Description
Specifications

Specially designed at conception for military use, the GUINAULT GA45, GB45/20 and GC20 Ground Power Units are the perfect solution for providing 400 Hz or 28 Vdc electrical power for regional aircraft.

Their compactness is unrivalled in the market (being only 1.1 m high), which significantly reduces the risk of accidents on the tarmac.

The strong performance of the dual voltage GUINAULT alternator makes it possible to use an oil cooled DEUTZ COMPACT engine, without water cooling. Maintenance and fuel consumption are reduced. The 9-phase GUINAULT alternator provides a high quality direct current (18 pulses).

A Low-Cost market-leading airline (being highly cost sensitive) selected the GUINAULT compact generator based on a comparative analysis of existing products available on the market.

The choice of the GUINAULT product was made, based upon the following criteria:

HIGH PERFORMANCES:

  • Permanent/peak current
  • Voltage/Frequency Transients

RELIABILITY AND ROBUSTNESS:

  • DEUTZ oil cooled engine
  • GUINAULT Alternator and electrical regulation
  • Stainless steel electrical box with excellent EMC
  • Full anti-corrosion protection: polyester canopy, plastic fuel tank and electro-galvanized steel chassis for long term utilization

EASY TO USE:

  • Excellent manoeuvrability due to reduced dimensions / weight and the leading front axle with ball bearing for low turning radius (= wheel base)
  • Control panel with clear indication and robust switches
  • Possibility to uncover entirely the device by swinging the canopy and opening the rear panel

REDUCING OF THE TOTAL COST OWNERSHIP:

  • Low maintenance cost
  • Optimized fuel consumption due to the excellent efficiency of the alternator
  • Integration of standard components as much as possible
  • Low cost of spare parts due to the choice of standard components as much as possible

MULTI-PURPOSE:

  • The GPU guarantees an adapted power supply for numerous types of aircrafts thanks to the high temporary overloads tolerated by the alternator and the Simultaneous Dual-Voltage operation possible for 400Hz and 28Vdc outputs.
