As part of the Professional Series, the E4-V+ offers outstanding performance for large residential and commercial applications, for flow rates up to 15.8 gpm (60 lpm).


  • System flow rates are validated to NSF 55 Class B Standards for maximum protection in larger homes and commercial properties.
  • LCD controller features a large backlit display, simultaneously displaying remaining lamp life, UV intensity status, and support information.
  • Optional monitored systems have a specialized UV intensity sensor and can stop the flow of water through the chamber should the UV performance fall below an effective level.
  • Built with 304 Stainless Steel to prolong life and eliminate degradation.
