Can UVC lamps function when the coil is operating with cold temperatures?
Yes, if the long life Clarion UV unit is used. It is designed for the cold, hazardous conditions of the coil region. The Clarion unit is based upon the cold cathode method, with an electrical circuit across the lamp body to heat and stabilize the UVC plasma within cold temperatures. The answer is “No” if you are trying to use a hot cathode lamp at the coil. Cold temperatures will profoundly affect the UVC intensity of this type lamp, even at 50° F. Also, cold temperatures will increase “glass-blackening” of the hot cathode lamp, further reducing intensity. And finally, the cold temperature ages these type lamp filaments faster; so the lamp has to be replaced sooner (six to eight months) compared to its expected life (one year) at room temperatures.
