Sterilight Dmd Qrtz Slv, Spv15, Sp740-Ho

This Sterilight domed quartz sleeve, a genuine Viqua-brand component, is a direct replacement for SPV15 and SP740-HO ultraviolet disinfection systems. In any UV system, the quartz sleeve is the clear, precision-made barrier that surrounds and protects the UV lamp, allowing germicidal ultraviolet light to pass freely through into the flowing water while keeping the lamp itself completely dry and isolated from the water stream. Because the sleeve is the medium through which all of that disinfecting light must travel, its optical clarity directly determines how much UV energy actually reaches the water, which is precisely why keeping a clean, intact sleeve in service is so essential to effective disinfection.

Over time and with continued use, quartz sleeves inevitably accumulate mineral scale, iron deposits, and film on their surface, and they can also crack from thermal stress or careless handling during maintenance. A fouled or damaged sleeve blocks UV light from reaching the water, reducing the system's disinfection effectiveness and potentially allowing microorganisms to pass through untreated. Replacing the sleeve restores full UV throughput so the system can once again deliver its rated disinfection performance against the bacteria and other waterborne pathogens it is designed to inactivate.

• Maintains maximum UV light transmission into the water
• Protects and isolates the UV lamp from the water flow
• Genuine Viqua / Sterilight replacement component
• Lightweight at approximately 1.0 lb
• An essential part of routine UV system maintenance

Ultraviolet disinfection is a popular and effective chemical-free method for treating well water and other private supplies against microbiological contamination, and sleeve maintenance is a central part of keeping it working properly. When cleaning or replacing a sleeve, handle the quartz very carefully and avoid touching the surface with bare hands, since the oils from skin can leave a residue that affects UV transmission. Always refer to your specific system's manual for the correct sleeve replacement interval and the proper installation procedure to ensure continued, reliable disinfection. Many owners coordinate sleeve cleaning or replacement with their annual lamp change, since the system is already opened up at that point and addressing both components together restores the unit to peak performance in a single service visit, minimizing the number of times the water supply must be taken offline for maintenance.
