CastleGuard VIQUA ultraviolet water disinfection systems provide chemical-free point-of-entry treatment designed to help inactivate common waterborne microorganisms as water passes through a stainless-steel UV chamber. The product family includes compact Standard Series systems for residential whole-home applications and higher- capacity PRO Series systems for large homes and light-commercial applications. Digital maintenance reminders, high-output UV lamps, and model-specific monitoring features help support reliable operation and straightforward service.
UV-C light provides an additional barrier against common waterborne microorganisms as water enters the home.
Ultraviolet treatment works without adding chlorine, salt, or other treatment chemicals to the water.
Installed at the point of entry, the UV system treats incoming water before it travels to kitchens, bathrooms, fixtures,
and water-using appliances.
Choose from 9/18 GPM Standard Series systems or 10/20/30 GPM PRO Series systems based on the application
and required UV dose.
Digital displays and audible reminders help owners track lamp service intervals rather than relying on memory.
PRO Series systems use a flow meter and UV sensor to provide real-time UV dose information and support higher-
demand applications.
Water Enters the UV Chamber. Incoming water enters the stainless-steel chamber after any required prefiltration or upstream water treatment.
The UV Lamp Produces UV-C Light. A high-output ultraviolet lamp sits inside a protective quartz sleeve and emits UV-C light into the surrounding water.
UV Energy Reaches Microorganisms. As water passes through the chamber, microorganisms are exposed to ultraviolet energy.
Microorganisms Are Inactivated. The UV treatment helps inactivate common waterborne microorganisms so they cannot reproduce effectively.
The Controller Monitors Lamp Operation. The system controller tracks lamp life and provides maintenance reminders; model-specific alarms and monitoring features provide additional operating feedback.
Treated Water Continues Through the Building. Water exits the UV chamber and travels to faucets, fixtures,band water-using equipment throughout the home or light-commercial application.

High-output lamp technology provides strong UV performance in a compact stainless- steel chamber.
Digital countdown timers and audible lamp-change reminders make routine service easier to track.
Standard Series constant-current control helps maintain stable lamp output during power fluctuations.
A compatible solenoid valve can stop water flow if UV performance falls below the required level on applicable monitored systems.

CastleGuard VIQUA UV systems use powerful UV-C light to help inactivate common waterborne microorganisms without adding chlorine, salt, or other treatment chemicals, while leaving the water’s taste, odor, minerals, and chemistry essentially unchanged.
The Standard Series (CG-UV10 and CG-UV15) provides reliable residential treatment with lamp-life countdowns and maintenance reminders, while the PRO Series (CG-UV-P10, P20, and P30) supports higher flow rates with real-time UV dose monitoring, flow-meter technology, and advanced diagnostics.
Sediment, iron, manganese, hardness scale, tannins, and turbidity can interfere with UV effectiveness, making proper pretreatment and system sizing essential. Routine lamp replacement and quartz-sleeve inspection and cleaning help maintain effective UV performance over time.
A UV system exposes water to ultraviolet light to help inactivate common waterborne microorganisms as water passes through the treatment chamber.
UV is a disinfection technology, not a particle or chemical filter. It does not remove sediment, hardness minerals, metals, chlorine, PFAS, or other dissolved contaminants. Pair it with appropriate filtration when those concerns are present.
No. UV treatment does not add chlorine, salt, or other treatment chemicals.
The Standard Series is designed primarily for residential whole-home applications. The PRO Series supports higher-demand residential and light-commercial applications and adds real-time UV dose monitoring, flow-meter technology, amalgam lamps, Cool-Touch fans, and advanced diagnostic features.
CastleGuard replacement data lists annual replacement for CG-UV10 and CG-UV15 lamps. PRO Series sourcespecifications state that the amalgam lamp can last up to two years.
The CastleGuard SKU workbook lists a 24-month or as-needed replacement interval. The sleeve should also be cleaned during routine service and replaced sooner if it is cracked, scratched, cloudy, or permanently stained.
UV performs best on visually clear water. Water with sediment, turbidity, iron, manganese, tannins, or excessive hardness may require pretreatment before the UV chamber.
Yes. The supplied PRO10, PRO20, and PRO30 specifications state that vertical installation is mandatory.
Choose a system based on peak flow demand and the required UV dose. CastleGuard offers CG-UV10 and CG- UV15 Standard Series options plus 10, 20, and 30 GPM PRO Series models.
