Scott Pure Water System Features


  • Clean Contact

    Anti-microbial touchpad surface and surrounding surfaces are manufactured and tested to protect against cross-contamination of germs within the workplace. Keep your point of use water purification system clean and your employees healthy.

  • 24/7-System Monitoring

    At the core of PHSI’s patented technology is a microprocessor that controls and monitors activated oxygen injection, filter life, water quality, and all other system functions 24 hours a day. Only the 3i water purification system can deliver this level of programmability and performance that keeps your water fresh and pure.

  • Activated Oxygen Injection

    During the ATS process, the water is oxygenated delivering FRESHNESS YOU CAN TASTE™. No other bottleless water cooler delivers this level of quality.

  • Pure Touch Dispensing

    The ergonomic design delivers an optimum dispense height and spacious dispense area for large containers which prevents germ contamination of the dispense nozzle. Since the 31 is a bottles point of use system, it can fit just about anywhere!

  • ATS-Auto Tank Sanitization

    ATS eliminates microbiological contamination and does away with the tedious and often overlooked task of sanitizing the holding tank.

  • Adjustable Temperature Control

    The cold water dispenses at 37degrees and will chill a glass for clients wanting that cool fresh glass of water. The hot water dispenses at 198 degrees great for teas and other hot beverages.

  • Sediment Filter – removes dirt, rust and silt
  • Carbon Block Filter – removes chemicals, solvents and chlorine
  • 80 GPD Reverse Osmosis Membrane – removes lead, mercury and arsenic
  • Granular Activated Carbon Filter – final polish
