What our customers say

Success stories from practice and partnership

"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."

"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."

"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."
