Welcome to the world of air and water.
Welcome to HAMMANN!
At HAMMANN company, we keep piping systems flowing since 1998. For 20 years we successfully apply our patended COMPREX® technique to municipal networks, drinking water installations and industrial systems removing residues of various kind efficiently and sustainably.
Developed by us, COMPREX® means efficient cleaning based on impulse flushing processes of air and water only – No chemicals needed. Personal site surveys by our experts allow applying COMPREX® tailored to your individual issues. Through science and innovation, we enable complete flow remediation for all kind of piping systems.

Developed by HAMMANN:
Our impulse flushing technique COMPREX® is solely driven by the fundamentals of physics: filtered air and water are fed into the corresponding pipeline passage by controlled impulses. This process creates air-water-packets passing the pipe with high speed. Subsequently, huge turbulences on the phase boundaries induce high forces of shear stress on the residues settled at the pipe walls until they are removed completely. The results are clean pipes and clean water – expeditiously, efficient and environmentally compatible.
Municipal water pipe systems
Raw water, drinking water or pressure mains - we are taking care of any issue related to the condition of your piping systems. Our portfolio comprises cleaning of piping systems as well as maintenance of instruments such as gate valves.
Drinking water installations in buildings
Problems with impurities and scales in drinking water installations in a building? We ensure that hygienically clean water comes from each tap as it is delivered by the water supplier. This can be done preventively, in cases of turbidity of the water or even in case of contamination with legionella.
Industrial (water-) pipe systems
Pipes in industrial networks are transporting liquids of various kinds. However, all these applications come along with the formation of scales such as biofilms and fouling. We are solving our costumer's problems with technical know-how and experience.
Maintaining pipe networks
With our COMPREX® netcare programm, we are offering reliable care service to municipalities to ensure hygienically and hydraulically proper conditions in the pipe network. This service package contains the inspection and remediation of hydrants und gate valves.
Always state of the art
Progress through research is one of our strongest driving forces which can be proven by our research activities with strong partners, e.g. the BMBF joint research project 'Mikrobielle Verockerung' (“formation of ochre by microbes”) in technical systems.
