Pretreatment System for Evaporative Cooling Equipment 

EVAPCO Water Systems has expanded its product offerings to include a capacitive deionization pre-treatment system focused on improving water efficiency. The EVAPCO Water Saver™ utilizes capacitive deionization technology to reduce dissolved ion concentration, thus lowering the makeup water conductivity prior to use in an evaporative cooling system. Makeup water entering the Water Saver™ passes through individual cylinders that contain oppositely charged supercapacitors. Dissolved ions (except silica) are removed from the water as they are absorbed onto the charged capacitors. A typical 50% ion reduction allows the operating cycles of concentration to be safely doubled without an increase in scale or corrosion potential. 

Water Saver™ Benefits

  • Improves water efficiency by increasing operating cycles of concentration
  • Reduces blowdown and treatment chemicals sent to drain
  • Routine monitoring by EVAPCO authorized service
  • Low cost of ownership
  • 75-90% recovery rate
