Basic
The UV-C lamps of PURION have a natural drop in performance over the duration of their lifetime. We guarantee that the lamp has reached the promised flow output after 10,000 hours. After this time, the lamp must be changed in order to guarantee the disinfection performance. The basic variant does not have a measurement of the lamp life and no sensor monitoring, so you are instructed to measure the term yourself, check the lamp at regular intervals and to check the reactor for any contamination.
Plus (OTC)
The UV-C lamp has a natural drop in performance over the duration of its lifetime. We guarantee that the lamp has reached the promised flow output after 10,000 hours. After this time, the lamp must be changed, the lamp runtime knife and the service life monitoring (OTC) signal the right time. The hours in which the lamp is switched on are counted and the values are output via an LED display. A green LED shines up to 9,000 hours, between 9,000 and 10,000 hours the pre -alarm is displayed with a yellow LED and after 10,000 hours a red LED lights up. So the right time is not missed to change the lamp.
Extra (OPD)
Sensor monitoring is integrated in this system to control the UV-C lamp. The UV-C performance of the lamp is permanently measured via a sensor that is attached in the middle of the stainless steel reactor and output via an LED display. If the UV-C lamp has more than 70% of the starting intensity, a green LED shines, between 50 and 70% a yellow LED shines as a pre-alarm and under 50% a red LED lights up. If the display is red, there is no longer enough UV-C intensity to ensure the promised flow. This can be due to the natural drop in performance of the UV-C lamp, for example, or pollution within the reactor.
Ultra (ESM)
The UV-C output of the lamp is measured directly via the sensor monitoring of this system. The sensor is attached in the middle of the stainless steel housing and always measures the current UV-C output, which is output using an LED display. With a rate of more than 70% of the start intensity, a green LED shines, between 50 and 70% a yellow LED appears as a pre -alarm and below 50% a red LED lights up. If the red LED lights up, it means that the promised flow output can no longer be guaranteed. The reasons for this can be the natural drop in performance of the system or pollution within the system. As soon as the red LED lights up, the additional built -in solenoid valve is automatically closed, so that there is no danger to the user. This solenoidal valve is powerless and therefore closes fully automatically even when the power fails.
