Hydraulic and aeraulic equipment

Clemessy specialises in designing and integrating test systems for hydraulic and aeraulic equipment. From assistance to expressing requirements right through to commissioning, our specialists carry out the systems necessary for assessing the performance and behaviour of your components and equipment.

Established in the west of France, the hydraulic expertise centre is located in a strategic place at the crossroads of the aeronautical industries, the naval shipyards in the west and the new technology sectors.

Hydraulics businesses

  • Designing hydraulic power supply units, pools or functions blocks
  • Maintenance of hydraulic components
  • Off-Shore equipment: taking into account ATEX environments
  • Conditioning, lubrication, filtration and filling modules
  • Compliance with certifications : BV, DNV, MARPOL, LLOYD’S REGISTER, ABS…
  • Installation and piping on site

This centre also proposes its experience when it comes to designing and supplying test facilities for industrial laboratories and R&D projects. These test facilities are dedicated to hydraulic test benches for mechanical loads and fluid test benches for testing parts.

Systems for performing tests on hydraulic and aeraulic equipment for all fluids

  • Mineral oils
  • Drinking and sea water
  • Heat transfer fluids, ethylene glycol
  • Fuel, diesel, kerosene
  • Aeronautical oils, skydrol
  • Naval oils, fhari
  • Air, gas

In order to assess the performance and behaviour of your components or equipment, these test facilities make it possible to carry out tests like:

Endurance tests

  • Fatigue test benches
  • Fluids : Pressure/Flow/Temperature
  • Mechanical : Force / Movement / Vibration / Torque / Speed
  • Thermal : climatic tests / hygrometry / thermal shocks
  • Chemical : Erosion / Corrosion / Salt mist / Sprays

Performance and yield tests

  • Characterisation test bench
  • Tightness check
  • Monitoring machine: air / water / tracing gas / helium / sniffing
  • Vibration tests
  • Vacuum tests
