  Product Features  
Intensity Monitor:
The controller visually displays the remaining lamp life and will go into alarm if the lamp fails. Monitored systems are equipped with a UV sensor which provides a continuous readout of UV intensity.
Space Efficient:
High UV output lamp technology allows for a smaller footprint while providing the same UV performance as a longer chamber.
Ease of Maintenance:
Audible lamp replacement reminder and countdown timer with digital display. A controller will also go into alarm if the lamp fails.
The constant current feature ensures stable UV lamp output, regardless of power fluctuations. High-performance UV lamp, rigorously tested to provide a consistent output over the entire lamp life (9000 hours).
Perfect for a wide range of whole-home, point-of-entry water treatment solutions in homes, cottages, or light commercial business applications.  
  Specially designed and tested Sterilume™ -HO lamps provide consistent and reliable ultraviolet output over the entire life of the lamp (9000 hours) to ensure continuous purification. High output lamps allow for small footprint while providing the same UV performance as a standard output lamp in a longer chamber.
Built with a durable stainless steel chamber to prolong life and eliminate ultraviolet light degradation.

Equipped to inactivate chlorine-resistant parasites such as Cryptosporidium and Giardia, harmful bacteria like E.Coli, and viruses not visible to the naked eye.
The system is simple to maintain and service allowing for easy lamp replacement.
  Safety-Loc™ connector with interlock that ensures power is disconnected before lamp can be removed.

Product Questions & Answers

Have a UV question that hasn't been answered? Live chat with a RainDance specialist for a quick answer!

Q: How does the UV system remove bacteria?
A: As water flows past the UV lamp(s) in a UV disinfection system, microorganisms are exposed to Ultraviolet light energy. Ultraviolet light alters the DNA material in cells so that bacteria, viruses, molds, algae and other microorganisms can no longer reproduce. The microorganisms are considered dead, and the risk of disease from them is eliminated. The process of UV Disinfection is accomplished without adding any harmful chemicals to your drinking water and does not distort the water or effect its pH value.

Q: Will a UV system remove iron bacteria?
A: No, iron bacteria is a different variety of bacteria that will coat the entire UV system in a slimy substance, causing fouling and costly replacement. Iron bacteria is not necessarily a harmful bacteria, it is more of a nuisance and requires a chemical oxidation followed by filtration for effective removal

Q: Do I need a water softener with a UV system?
A: If your water hardness is over 7gpg (120mg/L) a water softener is recommended to prevent scale build-up on the quartz sleeve and reduce cleaning and replacement frequency.

Q: Do I need a sediment prefilter?
A: Sediment, debris, and turbidity can "shade" the UV lamp intensity which prevents effective disinfection and may cause bacteria to pass through the UV system. To ensure the most effective treatment, we include a free 5 micron washable sediment prefilter for optimum performance of your UV system.

Q: Do I need a plumber to install?
 A: If you are handy and have basic plumbing skills you should have no problem with this installation. We provide detailed installation instructions, pictures, and offer several means of tech support for you or your plumber.
