From its Cincinnati base, comprex North America provides industrial and municipal pipeline cleaning services and builds mobile and stationary systems around its patented comprex® impulse-cleaning process. The company uses controlled pulses of compressed air and water rather than chemicals to remove deposits and biofilms from fluid-carrying systems, including complex plant equipment and heat exchangers. The comprex® process has supported drinking-water supply and industrial applications since 1997, with engineering services that range from onsite trial cleaning to customized system installation.
