The amalgam UV-C quartz germicidal lamp is a high-efficiency UV-C light source developed for professional disinfection applications. The lamp emits ultraviolet radiation at a wavelength of approximately 253.7 nm, which effectively damages the DNA and RNA of bacteria, viruses, moulds and other microorganisms, thereby preventing their reproduction and infectious activity.

Amalgam technology offers significant advantages over conventional germicidal UV-C lamps. The amalgam filling provides a more stable mercury vapour pressure, enabling higher UV-C output and more uniform operation across a wider temperature range. As a result, amalgam UV-C lamps can provide several times higher UV output, a longer service life and improved energy efficiency.

The special quartz glass envelope ensures excellent UV transmittance, maximising disinfection efficiency. When operated with a suitable electronic control gear or ballast, the lamp provides stable UV output, reliable performance and a long operating life.

One of the most important advantages of amalgam UV-C lamps is their stable lifetime output curve. While the UV output of conventional UV-C lamps may decrease significantly during operation, amalgam technology typically allows the initial UV-C output to decrease only from approximately 100% to 80% by the end of the lamp’s service life. This provides more predictable disinfection performance, greater operational stability and longer maintenance intervals.

Amalgam UV-C lamps are particularly recommended for high-performance industrial and professional systems, including water disinfection equipment, air-handling systems, industrial processes, food-processing applications and high-flow air or water UV-C systems where continuous and intensive disinfection is required.
