Descriptiontext

Hammann GmbH, operating commercially as Comprex®, is a family-owned German industrial services company founded in 1997 and headquartered in Landau in der Pfalz. The company specialises in mechanical, chemical-free pipe cleaning using its patented Comprex® impulse flushing method — a process that injects precisely controlled air-water pressure pulses into pipe systems to dislodge deposits, biofilms, and contaminants without chemical additives. An additional proprietary procedure, ExtraQt®, is offered for specialised applications. Service delivery is on-site and project-based, supported by field-deployed cleaning units such as the MCU-300. The company is led by Managing Directors Dipl.-Ing. Hans-Gerd Hammann (founder) and Vincent Hammann M.A., representing the second generation of family leadership.

Hammann serves four primary verticals: Municipal (water extraction, water distribution, wastewater disposal, and wastewater treatment infrastructure); Buildings (drinking water installations, fire suppression systems including PFAS removal, heating and district heating); Industry (production lines, CIP cleaning, cooling and tempering circuits, cooling lubricant systems, heat exchangers, viscous-media applications); and Medical (automated endoscope pre-cleaning). Named customers include Beiersdorf AG, Meffert AG Farbwerke, Framas Kunststofftechnik, MEG Rossbach, Stadtwerke Rüsselsheim, Stadtwerke Steinburg, Gemeinde Jemgum, and Eigenbetrieb Stadtentwässerung Langenhagen.

The business model is professional-services based: revenue is generated through project-based cleaning engagements, consultation, custom solution development, and related equipment sales or leasing. Go-to-market is direct enterprise field sales targeting municipalities, building operators, industrial facilities, and medical institutions, with international reach delivered through a global partner network that includes Downer, KraussMaffei, IES, EWR, Drain Jet Robotics, and others. The company markets quantified performance outcomes — up to 80% cleaning-time reduction, up to 90% water-consumption reduction, and up to 100x stronger cleaning effect versus conventional flushing — supported by customer test facilities in Landau.
