Hydro-Logic ARCS Automated Reclaimed Condensate System - 4 Stage Filter Array. The Hydro-Logic® Automated Reclaimed Condensate System (ARCS) works with any application that creates condensate water such as air conditioners and dehumidifiers, and successfully reclaims and purifies the condensate water that would normally go down the drain. Condensate water is low in pH, contains harmful heavy metals and can harbor pathogens and bacteria. Condensate water should never be used for any purpose without proper treatment.
