VIQUA Arros - 9 GPM UV Sterilizer

The VIQUA Arros 9 GPM UV Sterilizer from Trojan Technologies represents the newest generation of whole-home ultraviolet water treatment, engineered for streamlined installation and minimal maintenance. With flow rates up to 9 GPM, the Arros is ideally suited to homes, cottages, and light commercial applications seeking dependable, chemical-free disinfection that fits easily into existing plumbing.

Validated through microbial testing, the Arros has generated performance data confirming its UV dose delivery for inactivating Cryptosporidium, Giardia, Escherichia coli (E. coli), and fecal coliform. That validation gives homeowners confidence that the system is genuinely protecting their water against the pathogens that matter most, rather than relying on unverified claims. Because UV disinfection adds no chemicals and creates no disinfection byproducts, it preserves the natural taste of the water while keeping it microbiologically safe.

Innovative Features

• Treats flow rates up to 9 GPM for homes and cottages
• Tidal Chamber aligns inlet and outlet ports on a single plane for easier plumbing
• PolyProtect blocks UV light, allowing direct connection to PEX and other polymers
• All-in-one lamp design combines lamp and quartz sleeve in a single connection
• Stream Technology tracks lamp hours for timely replacement
• Flexible vertical or horizontal chamber mounting with rigid steel bracket

The Arros is packed with thoughtful engineering aimed squarely at simplifying the installer's life. Its Tidal Chamber aligns the inlet and outlet ports on a single plane, reducing the need for complicated plumbing rerouting and cutting the number of fittings, which lowers pressure drop. A more efficient chamber means a smaller, lower-power lamp can be used, resulting in a more compact and energy-efficient system overall. PolyProtect technology blocks stray UV light so the unit can plumb directly to PEX and other polymer materials without risk of UV degradation of the pipe.

The all-in-one lamp design unites the lamp and quartz sleeve in a single connection, eliminating the lamp harness and simplifying both installation and routine maintenance. A rigid steel mounting bracket ensures clean, repeatable alignment between bracket and chamber, eliminating sloppy installs, and the chamber installs either vertically or horizontally with a controller that accepts flow from either direction. Stream Technology tracks the actual hours the lamp is powered, enabling timely replacement for continued optimal performance. For modern, hassle-free whole-home UV disinfection, the VIQUA Arros 9 GPM delivers optimized performance with refreshingly simple upkeep.
