RCUV Ultraviolet Water Disinfection System

RainSoft’s Water Disinfection System Uses Ultraviolet Light Technology to Protect Your Family from Waterborne Cysts, Bacteria & Viruses

The RainSoft RCUV Series system reduces some of the most common microorganisms found in water without the use of chemicals.

The time-tested ultraviolet light technology used in the RCUV water disinfection system will provide many of the same benefits as distillation without removing beneficial minerals from your water. Additionally, unlike chemical treatments, it doesn’t leave behind unwanted residue or by-products that negatively affect the water’s flavor and odor. The system works by bombarding microorganisms with lethal doses of UV light. It is designed for use with visually clear water. Water that enters the UV disinfection system should be filtered to a minimum of 5 microns. Your authorized RainSoft dealer can help determine whether the RCUV Series is the best water treatment solution to meet your needs.

RAinSoft® RCUV Features & Benefits
Energy-Saving Process

Disinfection requires only a few short seconds of UV light exposure, requiring less energy than a typical household lightbulb. This makes the RCUV highly cost effective to operate.

Almost No Maintenance Required

Replacing the UV lamp once a year is the only service needed to maintain the RCUV system. Your RainSoft dealer will perform this task for you.

Ease of Operation

Visual and audible alarms let you know in advance when it’s time to contact your RainSoft dealer and have your system’s UV lamp replaced.

Step-by-step How Does It Work?
Installation & Water Entry

The RCUV water disinfection unit is installed in your home’s main water line. Water enters the unit and passes into the stainless steel UV light chamber.

UV Light Exposure

The water passes under an ultraviolet lamp that’s centered within a protective quartz sleeve inside the chamber, which is precisely engineered to evenly distribute the UV energy.

Effective Disinfection

Waterborne microbes receive short but lethal blasts of UV light, which destroy bacteria and render many viruses harmless. The disinfected water exits the unit, ready for use throughout the home.

Protection from Waterborne Cysts, Bacteria & Viruses

Understanding UV Water Disinfection

In RainSoft RCUV Series water disinfection systems, an ultraviolet lamp is centered within a protective quartz sleeve in the unit’s precisely engineered and polished stainless steel disinfection chamber. This ensures even distribution of UV energy to all water passing through the unit. Microorganisms are bombarded with a lethal dose of UV light, destroying bacteria and inactivating many viruses.

Ultraviolet disinfection provides many of the same benefits as distillation without removing beneficial minerals from the water. UV disinfects water using high intensity light energy. Unlike chemicals, it does not leave unwanted residuals or by-products in the water. Since there are no chemicals, UV does not affect the taste, odor or clarity of the water. For this reason, UV is often combined with other water treatment devices such as carbon filters, water conditioners and reverse osmosis to provide complete water quality solutions. Incoming water to the ultraviolet disinfection system should be filtered to a minimum of 5 microns. Your authorized RainSoft distributor can assist you in making this determination.

Do not use the RainSoft RCUV Series with water that is microbiologically unsafe or of unknown origin. For such applications,the RainSoft RCUV-NSF Series is required. These systems are not intended to convert wastewater or raw sewage to drinking water. The system is intended to be installed on visually clear water. Your local RainSoft dealer can assist you in making these determinations.
