R&D: Filtration experts

• Software for pressure vessel construction, e.g. AD, ASME
• 3D-CAD
• Multi-focus stereo microscopy, e.g. for researching filter media
• Gravimetric determination of amount of dirt with precision scales
• Online particle count for oil and water
• Mobile screw spindle pump 8 bar / 16 m³/h with FI
• Flow simulation: Computational Fluid Dynamics (CFD) with commercial and open source software
  • Calculation of transient flow behaviour for optimising e.g. back flushing processes and for investigating damage due to pressure variations
  • Particle simulations for optimising filter media, cyclones and filter housings
  • Calculation of stationary flow conditions for determining pressure losses and for optimising the technical flow of filter housings
• Structure analysis: Finite-Element Method (FEM)
  • Heat transfer and thermal expansion calculation
  • Tests and optimisation of prototypes
  • Contact analysis
  • Determination of force-deformation characteristics
  • Determination of natural frequencies (modal analysis)
  • Optimisation of component and material behaviour
  • Calculation of component deformations taking non-linear component and material behaviour into account

We test new designs again and again, using strict procedures in laboratory experiments and simulations on test benches, before the products are ready for the market. Selected suppliers are also involved in the development of innovative solutions.
