USWF-4CR1 Rack Mounted Whole House Ultraviolet Light Disinfection System 8 GPM

The USWF-4CR1 Contractor Series UV disinfection system is a reliable, economical, and chemical-free way to control microbiological contaminants including E.coli, Cryptosporidium and Giardia lamblia in residential and light commercial applications up to 8 GPM.

This system combines the power of UV disinfection with an integrated 10"x4.5" sediment prefilter. Because UV light only travels in a straight line any shadow or obstruction will reduce its efficiency. The integrated sediment prefilter ensures suspended particles like silt and sand that can block the UV light are removed for optimal system performance.

Designed with ease of operation in mind the system uses a bayonet style UV lamp connector which allows for quick lamp changes without tools, and the prefilter housing has a built-in drain plug to make changing the filter and quartz sleeve a breeze.

This UV system utilizes a low pressure, standard output UV lamp rated for 9,000 hours of continuous output, housed in a commercial grade axial flow UV chamber made from 316L grade stainless steel which offers better durability and corrosion resistance compared to the 304 grade stainless steel chambers used by many other brands.

The controllers for the USWF Contractor Series provide both visual and audio lamp out indicators in a splash-proof case. The ballast in the controller is also fully potted to further protect against possible water damage and to improve heat dissipation.

By purchasing a USWF-4CR1 you're not only getting a high quality UV disinfection system, but also peace of mind that the water in your home will have an extra level of protection.

Ultraviolet (UV) water treatment systems use specialized lamps that emit UV light at a wavelength designed to disrupt the cellular function of microorganisms. This light damages the DNA of bacteria, viruses, and other pathogens, preventing them from reproducing or causing infection. Because UV treatment neutralizes these organisms without chemicals, it offers a clean, safe, and low-maintenance solution for water disinfection. Once installed, the UV lamp operates continuously, disinfecting water around the clock with only minimal annual maintenance required.

Since UV light travels in a straight line and doesn't penetrate solids or shadows, prefiltration is essential. Removing sediment, silt, and other particles ensures the UV light can effectively reach and treat any microorganisms present. Additionally, minerals found in hard water can accumulate on the quartz sleeve that protects the UV lamp, potentially reducing its effectiveness. In areas with hard water, a water softener is recommended as part of the pretreatment process.

For water drawn from natural sources, professional testing and proper treatment are strongly recommended before it's used for drinking, cooking, bathing, or recreational purposes. UV disinfection provides a dependable, chemical-free, and environmentally responsible method for treating water and protecting against microbiological contaminants.
