The low pressure UV lamps typically find application in the disinfection of water, air and surfaces in the food and beverage industry as well as in waterworks, air conditioning and water sewage treatment plants.
About 40% of the electrical power can be used for disinfection as UVC radiation at 254 nm. If synthetic quartz glass is used as the lamp material, UV radiation at 185 nm is also emitted for oxidation processes.
The low pressure lamps are available in three types with varying lengths and different pinches and connectors:
- Classic mercury low pressure lamps have high efficiency, peak spectrum lines at 254 nm and are ozone-free
- Classic mercury low pressure lamps of synthetic or natural quartz glass with peak spectrum lines at 254 and 185 nm, and ozone-generating
- U-shaped lamps supplying high power in a compact design
