Cleaning with the comprex® process


“Ushe conclusion: The test of the Comprex unit can be rated as quite positive. The cleaning effect can be seen as very good, in some cases even blockages could be dissolved. 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.”
