About GUINAULT S.A
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.
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.
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).
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
