The company's pool systems PURION If there is no overheating problem, the UVC system should be switched on, but no water flow takes place.

For an optimal effect, we recommend changing the entire pool content at least three times a day. However, the system should be in operation at least 8 hours a day so that there is also sufficient ventilation and filtration. Our customer service will be happy to help you determine the right dimensioning.

There is a simple calculation for this: the pool content should flow through the UV-C system at least three times a day in order to kill a large part of the algae by mixing a corresponding mixing. If the algae growth is reinforced, for example, if the phases of extreme solar radiation or after strong rainfall or a thunderstorm, we recommend the circulation rate to four times upheaval. Regardless of the circulation rate, we recommend that the system have min. 8 hours a day in operation in order to enable sufficient ventilation and filtration.

If all three basic recommendations for the use of UV-C system in the pool area, the pool can be operated completely without chlorine. If necessary, the selective application of a biological flocculation means is worthwhile. However, our high-quality UV-C lamps allow a combination of chlorine and UV-C, since no ozone is created that would be reactive with chlorine.

The high-quality UV-C lamps of the brand PURION are durable and very powerful. They produce a very high UV-C content. The lamps we use in the pool area are also used in other facilities in drinking water preparation. The UV lamps used do not emit any radiation below 250nm, which excludes the formation of toxic ozone. Thus the systems of the PURION In combination with other preparation procedures that are used e.g. chlorine.

Our compact systems can be operated via regular sockets that are customary in household with 10A or 16A. Ideally, this is also secured with a separate FI/LS switch laid out on 30mA or better 10mA.

No, from our point of view, ozone should not be used in the pool area under any circumstances. Ozone is highly toxic. Excess ozone has to be destroyed again, whereby it is usually unclear how much ozone is left. In addition, Ozon reacts with chlorine, so that the effect of both procedures is greatly reduced. Cheap produced UV lamps often also emit radiation below 250nm, which means that ozone can be formed. This is with the systems of the PURION excluded.

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.

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.
