The PURION DVGW ZERT is a powerful UVC system for effective and reliable disinfection of drinking water. With an output of 400 J/m² at 3.4m³/h, the system is perfectly suited for single-family homes, apartment buildings and commercial units. It is certified and approved according to DVGW DIN 19294-1 as well as ÖNorm M 5873-1:2020-01-01, the water to be treated is thus disinfected both reliably and legally.

The system is offered including a mounting set for easy attachment of reactor and control box to the wall. The PURION DVGW ZERT is ready to plug in, i.e. in contrast to other certified systems, the following is required for installation no electrician is necessary.

The compact design allows easy lamp removal and lamp replacement without tools, for example at the end of the emitter's service life. For cleaning purposes, the quartz immersion tube system can also be dismantled or mounted without tools.

By default, the PURION DVGW ZERT is equipped with a 1 ½ " male thread, but there is also the possibility of an upgrade with the industry standard Tri Clamp, please contact our customer service for this.

Due to the special lamp design, this unit is also approved for temperature ranges up to 90°C and can therefore be used for legionella prevention.

The installation of the unit can be done horizontally or vertically, but we recommend the vertical installation, because the maintenance can be done a little easier. It is necessary to consider the usual installation rules for UVC systems: as close as possible to the extraction stations, as well as the last link of the water treatment chain.

Häufig gestellte Fragen

At what point does the UV-C system have to be installed in the drinking water cycle?

A UV-C disinfection system is always the last link in a water treatment chain, since the path to the withdrawal point should be kept as low as possible. Water filters in particular offer ideal conditions for settlement by bacteria. The freshly disinfected water would therefore germinate again if it would continue through the drinking water cycle after going through the UV-C system. Printing boilers should always be installed in front of the UV-C systems.

Why does the UV-C lamp have to be changed after 10,000 hours even though it still works?

Each UV-C lamp has a technical drop in the UV-C performance. The manufacturer guarantees that the system will reach 60% UV-C output after 10,000 hours. The specified data on the systems always refer to this 60% performance. However, the drop in performance continues to increase from a term of 10,000 hours. Therefore, the lamp still works, but there is no longer enough UV-C output for an optimal disinfection result.

When do I need a life of life?

A service life monitoring is recommended for all users who do not permanently let the system switch on. A change of the lamp is recommended every 10,000 hours, since the manufacturer also does not guarantee the performance, i.e. the amount of UV-C radiation dose required for safe disinfection.

Can this system overheat?

If there is no water withdrawal when the lamps are operated, the water inside the system heats up. With the 10W, 17W and 36W systems, this effect is negligible because the water temperature does not increase above 40 ° C. However, if the water is heated more than 40 ° C, as is possible when the 48W and 90W variant is operated, the lifespan of the lamp can be negatively influenced. In these systems, it is therefore recommended to ensure a steady water flow.

Does the system automatically switch on the water flow?

The UV system should be permanently switched on for various technical reasons:
1.) The UV system needs about 1 minute to achieve full performance.
2.) When igniting the lamp, as much energy is required as for operation over two hours.
3.) Each on and off cycle is at the expense of the service life.

How do I know which UV-C system is the right one for me?

It is not important to the average water consumption per day, but what maximum acceptance quantities can occur. Therefore, the correct drinking water system is determined by the existing withdrawal stations and the number of people in the house. A tap has fully turned on an output of 300 to 500 liters per hour. If in doubt, the next stronger system should be used.

Do you recommend fuel germination?

No, we advise flow reactors, as the maximum distance between the water to disinfect and the UV-C lamp is precisely defined. A tank collision system can only ensure a complete disinfection if it has a previously calculated revolution. In addition, flow reactors are much more efficient.

What do I need a sensor for and to what extent does it differ from the life of life?

A UV-C sensor is used to measure the UV-C output released directly on the lamp. This ensures significantly higher security for the user, since a drop in performance is directly signaled. This can be too bad transmission or a natural drop in performance of the lamp due to the eore of the recommended maximum operating time of 10,000 hours.

Can I use these systems as drinking water systems?

If in doubt, this must be clarified with the health department. The operating certificate for the systems in the download area of ​​the respective product pages of this online shop are available for this. We will also be happy to advise you personally on this topic. Alternatively, with the Purion DVGW Zert, we also offer a UV system certified both according to DVGW and Ö-Norm.

Which UV-C dose is used?

We use a UV-C dose of 400 J/m² for safe disinfection. This performance is sufficient to achieve a disinfection quota of 99.99% in compliance with the specified flow rate and transmission. Thus, water from a tank or container can be prepared precisely.
