ACC Cleaning System

Keeping the finned tube surfaces of your air cooled condenser or fin fan unit clean is imperative to maintaining optimal performance and reliability. Units fouled with dust, dirt, debris, pollen, leaves and other deposits can rob your plant of precious output. And as ambient temperatures climb, the impact of surface fouling will cost you even more. Utilizing the latest in precision high-pressure water jetting technology, Constant’s ACC cleaning system has been used in hundreds of power plants, petrochemical plants and refineries worldwide.
