- Restores UV System Effectiveness – Ensures your UV system delivers the required UV dose to protect water quality.
- Reliable Annual Service Part – Designed for routine replacement as part of normal UV system maintenance.
- Easy Installation – Direct replacement with no special tools required when servicing compatible systems.
Compatibility
Matching UV System
The UV Dynamics 400434 UV Lamp is a genuine replacement lamp for these UV Dynamics ultraviolet disinfection systems:
✔ UVD180
✔ UVD245
These systems are designed to treat residential or light commercial water supplies with effective UV-C disinfection.
Matching Quartz Sleeve
To pair with the 400434 lamp, the correct quartz sleeve is:
UV Dynamics Replacement Quartz Sleeve – Part #400435
- Fits UV Dynamics systems like the UVD180 & UVD245
- Protects the UV lamp from water contact while allowing maximum UV transmission
- Includes replacement O-ring for a water-tight seal
Why This Combination Matters
When servicing a UV system, both the lamp and quartz sleeve should be refreshed regularly:
- The lamp produces germicidal UV-C light to deactivate microbes.
- The quartz sleeve protects the lamp and ensures that the UV light passes through the water stream efficiently.
- Over time, quartz sleeves can become mineral-fouled or discoloured, which reduces UV effectiveness even if the lamp is new.
