CLEARFLOW P

CLEARFLOW P filtration systems in “hygienic design” are used in sensitive fields of biotechnology and food industry. Depending on the application, the filtration systems are designed especially with respect to the characteristic of the medium and the risk of contamination and fouling. Particularly when determining the filtration modules, all rheological and dynamic conditions of the medium being filtered are taken into account.

By interconnecting various filtration units in a filtration section, fractionated filtration procedures, for example, can be carried out. With this procedure, a target fraction of soluble or insoluble media components can be prepared.

In the control part, there are extended programme structures, safety devices and special sequences and regulations to guarantee a reliable and reproducable filtration. All filter systems are equipped with periodic backflushing to minimize the necessary amount of shut downs for cleaning purposes. Depending on the product sensitivity, the backflushing is carried out using sterile compressed air or with hygienic pumps and the filtered medium.

CLEARFLOW P systems consist of the following system components:

  • Pressure pump & circulation pump equipped with frequency converter
  • Circulation tank unit
  • Compressed air system
  • Filtrate pump with filtrate tank.
  • Stainless steel quality of all materials: 316L
  • Surfaces of Ra < 0.8 μm where they come into contact with the product, optionally with electropolishing
  • Filtration module made of polymers or ceramics
  • Hollow fibre modules, tubular modules or spiral wound modules
  • Pipework and fittings, e.g. in DIN 11864 and DIN 32676
  • CIP and SIP unit (optional) for cleaning and sterilisation
  • Compact frame to accommodate all pipes and units
  • Pre-filter units
  • Condensate system
  • Expanded sensor technology
  • Central control unit with SIEMENS PLC and touch panel


The systems are prefabricated as “package units” in the factory in Rheinbach and approved as part of a FAT (Factory Acceptance Test) in the presence of you as the customer.
