Operating Parameters

Western Quartz recommends an operating ultraviolet (UV) lamp wall temperature range between 650° and 750° centigrade. Higher temperatures can cause devitrification and/or distortion of the quartz envelope resulting in short lamp life. Temperatures below 650° centigrade can cause condensation of the mercury resulting in an unstable environment and premature darkening of the lamp body. The end seals have a temperature limitation starting at 250 centigrade and above as molybdenum starts to burn at this temperature and higher. Temperatures higher than this can result in oxidation of the molybdenum with subsequent seal failures.
