Keeping drinking water, extinguishing & heating systems reliably in operation

"I wouldn't have believed it if I hadn't seen it myself at the Landau test center. In detailed trials cleaning our products in test pipelines, we reached up to 60% savings in cleaning time and up to 90% in water consumption."

"The MCU-300 from Hammann represents an important component of our innovative industrial hygiene concept. The system is used at Meffert AG both for flushing pipelines and for cleaning stand-alone systems.
The cooperation with the colleagues from Hammann has worked very well since the beginning of the project.

Project planning and commissioning were transparent and professional. All inquiries are processed promptly, and ideas and optimization requests are discussed openly with our technical department even months after commissioning.
The MCU300 is intuitive for our employees to operate, can be used almost anywhere due to its dimensions, and works very reliably."

"Before flushing the main pumping station, we had a pump runtime of almost 20 hours and a pumping capacity of 250 m³ of wastewater. As a result of the flushing action, we were able to determine that on some days we achieve a pumping capacity of 270 m³ of wastewater with a pump runtime of 15 hours. This clearly shows an improvement in the efficiency of our system.We would also like to mention that thanks to Comprex® we were able to remove around 14 m³ of residue from the pipe that had accumulated over the years. This cleaning has helped to improve the performance of our system and prevent future problems."

"It is no longer possible to imagine our maintenance of injection molds without the cleaning technology from HAMMANN. The Comprex® cleaning is without alternative in very many applications. Thank you for the excellent and pragmatic service."

"The Hammann company was commissioned to clean the stainless steel gas pipe using their Comprex process. Success was already evident when the cleaning was carried out, as the escaping rinse water was heavily contaminated.
After cleaning and recommissioning, the aforementioned pressure fluctuations did not occur again. It was not easy to create the necessary inlet and outlet to the gas pipeline. It is also problematic to take a gas pipeline out of service for a longer period of time when there is no redundancy. Nevertheless, the effort was worth it, as the cleaning has had the desired effect."

"Our initial skepticism that comprex could be too intense for our piping system was unfounded. The pulse pressure always remains below the network pressure and so we don't have to worry about pipe bursts due to excessive pressure. The pulse flushing process can reduce the deposits in our old network so significantly that maintenance is absolutely economically viable compared to replacement."

"Our conclusion: The test of the Comprex® unit can be rated as thoroughly positive. The cleaning effect can be seen as very good, in some cases even blockages could be loosened. Due to the rather simple operation, the unit could be operated without any problems after the short instruction. No problems were encountered during the test phase.

At this point, we would like to thank you again for the test opportunity and the trust you have placed in us."

"We have had very good experiences with comprex and are very satisfied with the cooperation that has grown over the years. The Hammann GmbH technicians know our network, arrangements are quick and uncomplicated and the assignments are already a fixed part of our annual planning for network maintenance."
