QS-200 Domed End Compatible Viqua Sterilight Quartz Sleeve, S200RL models VH200, SPV-200, SC-200 (QJ23332DE)

This domed-end quartz sleeve, WrekinWater part QJ23332DE, is a compatible replacement for the Viqua Sterilight S200RL family of UV systems, including the VH200, SPV-200 and SC-200 models. It sits around the UV lamp, keeping it isolated from the water while allowing UV-C light through to disinfect the flow. Fit a new one when your existing sleeve has scaled, clouded or scratched.

Signs your quartz sleeve needs replacing

• Cloudiness, scale or scratching visible on the sleeve
• Brown or yellow staining building up on the glass
• Your S200RL-family unit's UV monitor sounding an alarm
• The sleeve has done around 12 months' service

Across the S200RL, VH200, SPV-200 and SC-200 models, the quartz sleeve does the same job: it keeps the UV lamp completely dry while letting UV-C light pass through the glass to disinfect the water flowing past it. As scale, iron staining or scratching build up on the sleeve, UV transmittance falls, so the water receives a lower dose even though the lamp still lights normally. Replacing the sleeve on schedule keeps disinfection performance where it should be.
