In cold storage and cold-chain work, standard UVC lamps don’t just underperform—they die fast. At -20°C, you’re not dealing with a textbook problem. You’re dealing with arc instability and a real drop in spectral output, day after day. When microbial control slips, the shop gets hit with recalls and downtime. We built a low-temperature UVC lamp to keep germicidal irradiance steady where conventional systems fade. What matters on the line isn’t marketing—it’s energy delivery. Our lamp holds stable 254nm output in sub-zero conditions by pairing a cold-tolerant arc tube with a thermally managed electrode and a pressure-matched envelope. The payoff is dose control you can count on, not guesswork. Rated lamp life is 1000 hours, so you schedule maintenance instead of chasing failures. Peak irradiance stays repeatable across the life curve, so disinfection performance doesn’t drift. Here’s why it holds up in practice. In refrigerated rooms and freezer tunnels, the system maintains arc stability without relying on external preheating, so you keep the UVC dose needed for microbial inactivation. The all-quartz envelope and ozone-free design are built for high humidity, frost cycles, and condensation. It’s the same hardware across stationary chambers, conveyorized lanes, and mobile sanitation rigs. Now, the real-world constraints. At -20°C, startup takes a bit longer. Let the lamp reach thermal equilibrium before you expect full output. Mounting has to account for reflector condensation—keep the fixture out of the cold airstream or use a sealed housing. And match ballast voltage and connector type to what you already run. Compatibility isn’t a nice-to-have; it’s what keeps performance consistent.
