Together with Arcadis and Kenbri Fire Fighting, Comprex® enables complete cleaning and decontamination of PFAS-containing foam extinguishing systems.
This is how the switch to fluorine-free foams (F3) succeeds – legally compliant, documented and sustainable.
Why action is needed now
PFAS (“per- and polyfluorinated alkyl compounds”) are among the so-called perpetual chemicals. They are contained in older foaming agents (AFFF) and can cause permanent damage to people and the environment. The EU is planning a far-reaching ban on these substances, and foaming agents containing PFAS may no longer be used in many applications.
This means for operators of extinguishing systems:
-
Old foam concentrate must be disposed of properly.
-
Systems must be cleaned and decontaminated before fluorine-free foams can be used.
-
Proof of cleaning is mandatory for authorities and insurers.
We accompany you every step of the way – from the analysis to the clean, certified conversion of your extinguishing system.
Strong partnership for reliable results
Three specialists work hand in hand on PFAS decontamination:
- Comprex® ensures the mechanical deep cleaning of the pipe network with air-water impulses.
- Arcadis supplies Fluorofighter®, the chemical component that reliably dissolves PFAS residues.
- Kenbri Fire Fighting contributes its expertise in foam concentrate technology, mixers and recommissioning.

Together we implement a two-stage cleaning process:
Pre-cleaning with Comprex®
The system is completely flushed, old foam concentrate residues and loose deposits are removed.
Deep Clean with Comprex® + Fluorofighter®
The system is flushed with increased temperature and chemical support in order to completely dissolve even deep-seated PFAS residues.
The result is a fully coordinated process that removes all residues from the system – documented, tested and ready for the use of fluorine-free foams.

Scientifically sound, proven in practice
Our cleaning principle is based on the Sinner’s circle – the interplay of mechanics, chemistry, temperature and time.
While conventional water flushes only rely on time and flow, our method makes targeted use of all four effective factors: Mechanics through the Comprex® impulses, chemistry through Fluorofighter®, increased temperature for intensification – and optimized flushing time for maximum effect.
The result: fast, deep cleaning with minimal water consumption, ideal for PFAS-contaminated foam extinguishing systems.
Advantages at a glance
Comprex® dissolves deposits and PFAS films using impulse energy, while Fluorofighter® breaks the chemical bond of the residues.
Partially filled pipes and pulsating flow ensure intensive flushing without long downtimes.
All flushing media are collected, filtered and disposed of properly.
After cleaning, the result is confirmed by laboratory analysis. The risk of a rebound is also significantly reduced by removing the contaminated sites in the PreClean phase.
Every cleaning is monitored, logged and documented in a traceable manner.
