Cost Reduction

  • No use of filter aids like DE
    • No purchasing, quality assurance, storage, preparation, health and safety risk management or disposables
  • Reduced beer losses
    • Solids discharge with high % of dry matter
    • Single pass process without any beer retentates after batch end or brand changes
    • Special membrane block design reduces dead volume
    • Empty modules by forward flow using CO2
  • Reduced energy consumption
    • “Zero retentate” crossflow filtration with minimum energy input
    • Low crossflow velocity
    • No internal cooling
  • Reduced water and chemical consumption for cleaning
    • Low hold-up volume in membrane blocks
    • Intelligent cleaning liquor management in terms of media re-use
  • Environmental friendly cleaning
    • No use of chlorine
    • Only simple technical grade chemicals
  • High production safety
    • Cluster technology allows Module Functioning Test (MFT) and enable ongoing production availability
  • Reduced labor costs due to full automation
  • Reduced CAPEX
    • No need for internal cooling or retentate tank due to single pass crossflow filtration
    • Eliminates need for additional particle or fine filtration
    • Continuous operation resulting in smaller system and footprint (standard PROFi system)
    • Flexible operation resulting in less bright beer tank (BBT) capacity required
    • No pre and post runs even when changing from dark beers to light beers
  • Reduced OPEX
    • Continuous filtration (standard PROFi system)
    • Stable filtration cycles nearly independent of incoming beer, yeast and particle load
    • 24/7 operation (standard PROFi system)
    • Very flexible on different brand changes and whatever the beer stabilization method used
    • Low energy, water and chemical demand
    • Low waste stream
  • Higher system availability
    • Fully automated, 24/7 operation
    • Clearly defined filtration and cleaning cycle times
    • Forward flow module emptying
    • No additional handling of pre and post runs
    • Cluster technology

Excellent Beer Quality

  • Low crossflow velocity with reduced shear forces
  • High clarification efficiency of centrifuge and membrane system
  • Negligible oxygen pick-up from process
  • No differences in analytics and sensory to traditional filtration methods

Microbiological safety due to MFT

  • Modules can be tested in-situ before production and removed from service if any defect detected


  • No filter aids to dispose
  • Reduced water consumption and waste stream
  • Reduced chemical consumption
  • No use of chlorine and only simple technical grade chemicals used for cleaning
  • Low energy consumption
  • Low CO2 footprint
  • Low water footprint

Consumer Protection

  • Best product traceability
  • High process safety
    • In-situ module functioning test
    • Fully automated system


  • Low investment costs for increased capacity due to modular design
  • Fast product / brand change due to forward flow module emptying
