A dedicated hydraulic laboratory and specialist capabilities in multiple locations

Our PVT bench, which went into service in 2018, is an additional piece of equipment to the existing ones. It performs three types of stresses: in cyclic pressure, vibration and temperature in a climatic chamber. It is dedicated to all types of vehicle engine assembly such as cooling circuits, hoses and pumps. This versatile bench accepts very wide test ranges to meet the specifications of the main car manufacturers.

The climatic values of the new PVT bench from -40°C to + 140°C for the fluid(a mixture of Glycol and water), and from -40°C to +175°C for the outside temperatureare combined with a static or cyclic pressure between 0 and 5 bar.

The flow rate of this test bench can reach 15 m³/h allowing 6 to 8 specimens to be tested simultaneously according to the requirements of the different reference standards.

The vibration spectrumcovered ranges from a travel of up to 50 mm peak to peakto a random profile of up to 27g RMS.

The combination of all these test parameters allows us to propose new, very complete campaigns, carried out in a single step.  As the parameters are set to accept those of the main car manufacturers, the start of campaigns is fast, their frequency is thus fluidized; and waiting times for their completion are considerably reduced.
