Limescale deposits inevitably build up inside sanitary installations during operation. Lime deposits come from urine, in vacuum systems the sewage is more concentrated than in gravity systems and vacuum lowers the boiling point of water to increase scaling tendency. These deposits reduce the duct cross-section which increases the risks of piping clogging and reduces operating efficiency. 

Unlike traditional piping maintenance solutions, Evac CleanVac operates automatically by slowly dosing a small amount of CleanVac chemical into the system through our proprietary EDP dosing unit which is integrated into the canister. Cleanvac is a blend of naturally fermented organic acid and eco surfactants specifically designed to clean and descale vacuum piping toilet systems. The ingredients work synergistically, with the surfactants removing the loose, soft organic matter thereby enabling the organic acid element to reach and dissolve the scale deposits with maximum efficiency in the minimum amount of time. 

Cleanvac is designed to work with our STP solutions, unlike traditional strong acids this has no negative effects on the biological mass in the sewage treatment system. 

A separate cleaning procedure is also available for manual / problem solving where they system may have already generated urinal scale.
