This UV-Set consists of a single-sided sealed quartz protection tube, which is mounted at the other end in a stainless steel immersion head, a UV emitter, the control box with an electronic ballast, and the connecting cables.

The immersion head sits tightly in the supplied threaded sleeve DN 40. The threaded sleeve can be easily welded onto a curved tank surface. The supplied hex nut DN 40 also secures and stabilizes the system. The function of the UV emitter, which is housed in the quartz protection tube,
can be monitored through the transparent cap on the immersion head. A control light indicates, for example, lamp failure or cable break. A potential-free contact associated with it can be used for external signaling or for switching actions.

**Optionally, the PURION weld in UV-Set can be equipped with shard protection.**

The UV emitters used are characterized by long service life, high disinfection performance, and low energy consumption.
The compact design allows for easy and tool-free lamp removal and replacement, for example, at the end of the emitter's service life. For cleaning purposes, the quartz immersion tube can be easily disassembled or assembled.
