An overview of the different monitoring levels and their characteristics

Basic

The UV-C lamps from PURION have a natural performance drop over the duration of their lifetime. We guarantee you that the lamp will reach the promised flow performance exactly after 10,000 hours. After this time, the lamp must be replaced to ensure disinfection performance. The Basic variant does not have a lamp life measurement or sensor monitoring, so you are dependent on measuring the runtime yourself, regularly checking the lamp, and inspecting the reactor for possible contamination. 

Plus (OTC)

The UV-C lamp experiences a natural decline in performance over its lifetime. We guarantee that the lamp will achieve the promised flow performance after 10,000 hours. After this time, the lamp must be replaced, and the lamp runtime counter and lifetime monitoring (OTC) will signal the right time. The hours the lamp is on are counted and displayed via an LED indicator. Up to 9,000 hours, a green LED lights up, between 9,000 and 10,000 hours, a pre-alarm is indicated with a yellow LED, and after 10,000 hours, a red LED lights up. This ensures the right time for lamp replacement is not missed.

Extra (OPD)

For safe monitoring of the UV-C lamp, this system includes sensor monitoring. A sensor located in the middle of the stainless steel reactor continuously measures the UV-C performance of the lamp and displays it via an LED indicator. If the UV-C lamp has more than 70% of the initial intensity, a green LED lights up, between 50 and 70% a yellow LED lights up as a pre-alarm, and below 50% a red LED lights up. If the indicator shows red, there is no longer enough UV-C intensity to ensure the promised flow. This could be due to the natural decline in performance of the UV-C lamp or contamination within the reactor.

Ultra (ESM)

Through the sensor monitoring of this system, the UV-C output of the lamp is directly measured. The sensor is mounted in the middle of the stainless steel housing and always measures the current UV-C output, which is displayed via an LED indicator. At a rate of more than 70% of the initial intensity, a green LED lights up, between 50 and 70% a yellow LED appears as a pre-alarm, and below 50% a red LED lights up. When the red LED lights up, it means that the promised flow performance can no longer be guaranteed. Reasons for this can be the natural performance decline of the system or contamination within the system. As soon as the red LED lights up, the additionally installed solenoid valve automatically closes, so there is no danger to the user. This solenoid valve is de-energized and therefore also closes fully automatically in the event of a power failure.
