With a total capacity of 8,000 l/h, the PURION 2500 90W Dual is an extremely large UV-C disinfection system that is mainly used in hotels and large apartment buildings. Technically, this system is based on two normal PURION 2500 90W, which are connected in series. This doubles the dwell time of the water in the system and therefore more water can be disinfected. The UV-C disinfection process specifically dissolves the DNA compounds of bacteria and viruses, which means that they are considered to have been killed. The taste and smell remain unchanged and the composition of the water is retained. With this low-maintenance and reliable UV-C disinfection system, the lamps can be easily changed during operation. Such a change is rare, as the lamps have a very long service life. The PURION 2500 90W Dual gives customers and tenants the certainty of drinking clean and germ-free water.

Thanks to a wide-voltage ballast, this system is designed for a voltage range of 85-264V and can therefore be used in many different countries. The system is equipped with a Euro plug and can also be used for other plug types with an adapter (not included).

This system is a flow-through system. It requires a low, permanent water flow, as the UV-C lamp heats the water to such an extent that the service life of the UV-C lamp can be impaired.

This UV-C disinfection system from PURION meets all the technical requirements of the Drinking Water Ordinance. The stainless steel 1.4571 used is also used in the food industry and therefore complies with the standard. The required UV-C dose of 400 J/m² with a UV-C transmission of 90% T1 cm is achieved in compliance with the prescribed maximum flow rate. This UV-C system therefore achieves a disinfection rate of 99.99%, as required by law. For trademark reasons, this system does not have a DVGW-Therefore, in individual cases it must be clarified with the health authority whether the UV-C disinfection system can be used.

Frequently asked questions:
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.
