In continuous water lines, you can’t afford to wait on microbial control. When flow rates ramp up, the usual tricks stop working, and microbes slip past. The only answer that makes sense is a UVC system that hits the germicidal dose in seconds—no chemicals, no residue. What actually matters under the hood We spec low-pressure, high-output mercury vapor lamps with a stable 254 nm output—the wavelength microbial DNA and RNA soak up hardest. Peak irradiance is engineered to clear 30 mW/cm² at the sleeve surface, and the quartz sleeve keeps UVC transmission above 90%. The lamp arc length and reflector geometry are matched to the channel cross-section so you get even dose across the stream, not a hot spot in the middle and a cold edge. Dose is irradiance multiplied by exposure time; get the hydraulics right and you can hit 40–60 mJ/cm² in under 3 seconds—enough to knock out bacteria and viruses on the fly. Why this fits continuous water work It runs with the flow. Lamps are mounted inline, so the entire stream gets irradiated as it moves, not in batches. No waiting for heat-up, no chemical contact time to chase. Energy draw is modest—typical arrays pull far less than the pumps and heaters you’d lean on for thermal disinfection. Maintenance is straightforward. Lamp output decays predictably; plan replacements around the 8,000–9,000 hour mark to keep dose consistent. The shop-floor details you can’t skip UVC intensity dives when fouling builds up. Hard water and organic films cut transmission fast, so pre-filtration and periodic cleaning aren’t optional—they’re mandatory. Alignment matters as much as anything. Even a 1–2 mm offset can throw a shadow and gut your effective dose. Don’t eyeball sleeve clarity—verify it with a UVC radiometer. Treat ozone-free as the baseline, but still confirm lamp type and sleeve so you don’t get ozone formation at the short wavelengths.
