Flozone’s quality water management prevents the accumulation of scale, algae and biofilm. Our results have been proven again and again with chiller openings and examinations. In every instance examination of HVAC systems employing Flozone Services have revealed clean chiller tubes. If fouled or scaled chiller tubes are found to be caused by Flozone Services; we will reimburse our customer for the expense of having the tubes cleaned. By design, cooling towers will accumulate airborne particles which in time will accumulate in the sump, but with proper water treatment a cooling tower should not accumulate visible scale, algae or biofilm on the wetted surfaces. Our Comprehensive Service Plan includes periodic removal of accumulated dust/dirt/debris from the sump, and should a customer’s cooling tower ever display an accumulation of scale, algae or biofilm, we will clean the cooling tower at no charge.
