GUINAULT S.A

Aircraft Air Start Units, Ground Power Units, Air Conditioning Units & Frequency Converters

GUINAULT Company has been designing and manufacturing aircraft Ground Support Equipment (GSE) since 1949. Today, GUINAULT is an independent and privately owned company certified ISO9001/2015 which offers a very modern range of products dedicated to all type of aircraft.

Today, more than 20,000 GUINAULT GSE are in operation world-wide in more than 100 countries over the five continents. GUINAULT is the only company, exclusively focused on the design and manufacturing APU-OFF solutions, including GPU, ASU, ACU.

Specialization, and in-house expertise are key factors at GUINAULT to offer superior products, ensuring the highest reliability, the highest performance to really substitute to the APU on the ground:

400Hz alternator design, (manufactured by GUINAULT in France), digital electronics, power electronics, industrial refrigeration, thermodynamics are in house expertise.

Thanks to its unique specialized experience in the APU-OFF solutions for decades, GUINAULT claims to be the partner of choice for the airlines, handlers and any third parties looking for savings and emission reductions trough the APU-OFF at the airport.

Because the return on investment for an APU-OFF solution (GPU, ASU, ACU) is impressive, because the reliability of the equipment generates valuable kerosene savings, because too many APUs are still running on the airports due to GSE quality/performances/reliability issues,  GUINAULT pays a great attention to the quality of manufacturing, the selection of components, the tests, to ensure the highest performance and reliability. The digital technology is designed in house, to ensure the highest reliability in airport conditions, and to include dedicated service functions to the APU-OFF target.

For all these reasons, GUINAULT is a first choice GSE partner for providing power solutions to handlers, Airports, Airlines, Aircraft/helicopter OEM and Military Armed Forces.

Aircraft Ground Power Unit (GPU)

Whilst on the ground, an aircraft requires special electrical power: 400Hz or 28Vdc.

The use of a ground power unit (GPU) instead of either an aircraft engine or Auxiliary Power Unit (APU) ensures very significant savings in terms of fuel consumption and maintenance.

Also, it is environmentally friendly, as it greatly reduces noise level and CO2 emissions at the airport.

GA90, GA140 and GA180

The GUINAULT mobile 400 Hz Ground Power Unit for aircraft from 90 to 180 kVA ensures the supply of electrical power to both civil and military aircraft, of all types in the most extreme environments. Their ultra-sturdy design is fully protected against corrosion and is engineered to withstand harsh conditions in airport environments. The modular design enables the integration of numerous options within a universal standard. The logical commonality of elements assists in the functional understanding of the machine, and contributes to the quality of maintenance.

In remote area, mains power might not be available. A diesel driven ground power unit is then the suitable solution.

ADVANTAGES

  • Performance and efficiency under extreme conditions (- 40 / + 50ºC)
  • Sturdiness and reliability
  • Maintenance access, modular construction
  • Ease of use
  • Versatility
  • Low Total Cost of Ownership

GA45, GB45/20 and GC20

Another option for remote area is our compact Ground Power Unit; Specially designed at conception for military use, the GUINAULT compact 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).

SA90 and SA180

If 50 or 60 Hz power is available, the GUINAULT Frequency Converter will offer clean low harmonics, low noise and very reliable 400Hz or 28Vdc electrical power. Whether operated in a maintenance hangar, bridge mounted, fixed on the ground, or towable, the unit remains extremely reliable, quiet, and user-friendly.

ADVANTAGES

  • Versatility : synchronization, extremely cold and hot conditions, variable frequency, 28 Vdc options
  • Performance and efficiency
  • Robustness and reliability
  • Silence and comfort
  • Ease of use
  • Reduced maintenance

Aircraft Air Start Unit (ASU)

Although most aircraft are fitted with an onboard APU to start engines, an Air Starter is needed should the APU fail.

Even if the aircraft is allowed to fly if the APU is out of service, it cannot start its engines.

The Air Start Unit requires high reliability in order to avoid AOG (Aircraft on Ground) in case of failure of an APU (Auxiliary Power Unit). It must be able, at any time and for any type of aircraft, to provide the necessary compressed air (42PSI of pressure) to run the turbines and perform the start-up.

GS180, GS280 and GS400

GUINAULT designed the safest Air Start Unit in the world using components known for their reliability, such as Deutz, Scania, and MTU engines, coupled with GHH RAND screw compressors. The use of electronic regulation allows them to operate in the best conditions and thus improve their lifespan, to limit noise at airports, and significantly reduce fuel consumption.

ADVANTAGES

  • Sturdiness and reliability
  • Optimized design
  • Ease of use
  • Electronic control
  • Ease of maintenance
  • No risk of obsolescence of the control system

Air Conditioning Unit (ACU)

Air Conditioning units (ACU) are designed to take over the functions of the aircraft APU and maintain the appropriate temperature within the cockpit and the cabin of any aircraft during pre-flight servicing, loading and maintenance.

This alternative dramatically reduces CO2/NOx emissions and noise level while leading to major savings both in fuel and the maintenance cost ofthe on-board APU.

GUINAULT units integrate the latest industrial cooling technologies and offer the highest efficiency and performance in the market.

Available in trailer mounted, truck mounted, GUINAULT Air Conditioning units suit all types of aircraft in all climates.

Completely self-contained, with compact design and very low noise level, GUINAULT Air Conditioning units can be operated at the gate or for maintenance purposes in a hangar.

ADVANTAGES

  • Performance and efficiency under extreme conditions
  • Robust and reliable
  • Simple operation
  • Remote monitoring and maintenance
  • Optimized maintenance access, thanks to modular construction

Combo Unit (ACU combined with 400 Hz / 28 Vdc power supply)

GUINAULT GF15 Combo Unit combined Air Conditioning Units / 400 Hz are designed to replace an aircraft’s APU and maintain the correct temperature in the cockpit and cabin during pre-flight operations, boarding and maintenance. These Units make it possible to meet the needs and requirements of code B and C civil aircraft in continental, tropical or desert climates.

ADVANTAGES

  • Performance and efficiency under extreme conditions
  • Robust and reliable
  • Simple operation
  • Remote monitoring and maintenance
  • Optimized maintenance access, thanks to modular construction
  • Versatility

Its ultra-sturdy design is fully protected against corrosion and is engineered to withstand harsh conditions in airport environments. The logical commonality of elements assists in the functional understanding of the machine, and contributes to the quality of maintenance.

ADVANTAGES

  • Performance and efficiency under extreme conditions (down to -30°c)
  • Flow, pressure and temperature electronic control with aircraft selection
  • Maintenance access, modular construction
  • Low Total Cost of Ownership
  • Sturdiness and reliability
  • Approved by German Berufsgenossenschaft
