Viqua D4 Premium

Ultraviolet (UV) disinfection is a highly effective means of neutralizing microbes without the use of chemicals. If you are on a private water supply, it is your responsibility to ensure your water’s safety. Installing a UV system on a municipal water supply provides peace of mind when aging municipal infrastructure fails.

The D4 Premium is the last innovation from VIQUA, combining the reliable D4 model with the new LCD Interactive Screen.

  • Highly featured whole-home UV disinfection system with graphical interface designed for recommended flow rates up to 12 gpm (45 lpm)
  • Overall foot print is extremely compact due to advanced lamp/chamber technology

This new controller features a large LCD backlit display for easy reading, simultaneously displaying lamp life remaining, UV Intensity Status, support contact information, and a lamp replacement reminder that indicates when the lamp needs to be replaced, ensuring continued water safety.
