The UV oxidation lamp and 0.2 micron final filter support analytical and organic chemistry applications.\u003c\/p\u003e\n\u003ch3\u003eWhat voltage and power does this system require?\u003c\/h3\u003e\u003cp\u003eThe WC311UVTB operates on 220V at 50 Hz. Confirm your site power matches this specification before installation.\u003c\/p\u003e\n\u003ch3\u003eWhat are the dimensions and weight of the unit?\u003c\/h3\u003e\u003cp\u003eThe chassis measures 21.6\" × 14.7\" × 14.4\" (54.8 × 37 × 36.5 cm). Shipping weight is 36.4 lbs, and the unit installs on a benchtop or wall mount.\u003c\/p\u003e\n\u003ch3\u003eHow does the system reduce TOC?\u003c\/h3\u003e\u003cp\u003eA dual-wavelength UV oxidation lamp at 185\/254 nm reduces total organic carbon and sterilizes bacteria. An integrated TOC monitor provides real-time tracking, and TOC output stays below 5 ppb.\u003c\/p\u003e\n\u003ch3\u003eWhat feed water quality is needed?\u003c\/h3\u003e\u003cp\u003eFeed water must measure below 20 µS\/cm. Verify your incoming supply or pretreatment meets this threshold to maintain rated performance and flow.\u003c\/p\u003e\n\u003ch3\u003eHow are the cartridges replaced?\u003c\/h3\u003e\u003cp\u003eCartridges use a quick-change, no-tools design with premium ResinTech ion-exchange media.
