Viqua Sterilight QS-320 UV Quartz Sleeve

Description

The Viqua QS-320 UV Quartz Sleeve is a genuine replacement quartz sleeve designed for select Viqua/Sterilight UV water disinfection systems. Made from high-purity quartz glass, this sleeve protects the UV lamp from direct contact with water while allowing maximum ultraviolet light transmission for effective, chemical-free microbial inactivation.

Quartz sleeves are critical to proper UV performance — when they become cloudy, scratched, or impossible to clean, they should be replaced to ensure your system continues to deliver reliable disinfection.

Maintenance & Replacement

• Inspect Annually: Check the quartz sleeve whenever you replace the UV lamp.
• Clean as Needed: Mineral deposits, iron, or other buildup can reduce UV transmission — clean gently with a soft cloth and appropriate cleaner.
• Replace When Required: Replace if the sleeve is scratched, cracked, or cannot be restored to clear transparency after cleaning.
• O-Ring Care: Replace O-rings during maintenance to ensure a proper seal.

Proper maintenance helps ensure that the UV system continues to deliver the correct UV dose for effective disinfection.

Why Quartz Sleeve Matters

The quartz sleeve protects the UV lamp and ensures maximum UV light reaches the water. Over time, scaling or deposits on the sleeve can block UV transmission, significantly reducing system effectiveness even if the lamp is still operating. Replacing the quartz sleeve as part of your annual maintenance cycle is essential for reliable, chemical-free water treatment.
