Lamp Technology

atg UV Technology systems utilise two key lamp technologies: -

1. Low Pressure Amalgam lamps offer unparalleled electrical efficiency, long and predictable lamp life (generally 12000 hours), and are unaffected by changes in water temperature.  A correctly run Amalgam lamp is 38-42% efficient; so a 320watt lamp is capable of delivering 134 watts of UV at 254nm.  These lamps produce a monochromatic output at 254nm, the germicidal region for effective disinfection of all known micro-organisms.  

2. Medium pressure lamps offer the same disinfection properties as low pressure lamps at much greater levels.  Additionally medium pressure lamps also have the ability for TOC reduction, De-ozination, and chlorine removal.

For a number of applications, medium pressure lamps are incorporated due to their small footprint and short arc length. e.g. Retrofits into existing small footprint facilities.  Our UV monitors can be offered as NIST traceable devices , and fit into dry ports that permit reference monitors to be inserted without breaking a water seal to validate the lamp output. In all cases the sensor technology we use is specific to germicidal UV and blind to visible light and IR.
