WrekinWater supplies it as a direct replacement when the original sleeve has scaled, clouded or cracked with age. The sleeve sits inside the UV chamber around the lamp, so getting the right part number matters for a proper fit.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e320204-1028-01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible system\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHanovia 230 UV disinfection unit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSleeve type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOpen-ended quartz sleeve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFused quartz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eWrekin Water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eSigns you need this part\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThe Hanovia 230 controller shows a low UV-transmittance or dose warning.\u003c\/li\u003e\n\u003cli\u003eThe sleeve looks cloudy, scaled or scratched when you inspect it.\u003c\/li\u003e\n\u003cli\u003eWater taste or clarity has changed even though the UV lamp is still lighting normally.\u003c\/li\u003e\n\u003cli\u003eThe sleeve is original to the system and has never been replaced or descaled.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe quartz sleeve sits between the UV lamp and the water, shielding the lamp from direct water contact while still letting UV light pass through to do its job. Over time the sleeve can pick up scale, staining or fine scratches, and even a small drop in UV transmittance through the sleeve means less effective disinfection reaching the water, even though the lamp itself may look and behave as if it's working fine.\u003c\/p\u003e\n\u003cp\u003eWrekinWater is a family run water treatment specialist based in Bettisfield, Shropshire, with more than 50,000 customers served over 15 years and an \"Excellent\" Trustpilot rating.
