PURION Pool 20 PVC-U Basic

PURION pool systems are not subject to overheating problems if the UVC system is switched on but there is no water flow.

For optimal effect, we recommend circulating the entire pool contents at least three times a day. However, the system should be in operation for at least 8 hours a day to ensure sufficient aeration and filtration. Our customer service will be happy to help you determine the appropriate sizing.

There is a simple calculation for this: the pool contents should flow through the UV-C system at least three times a day in order to kill a large part of the algae through appropriate mixing. If algae growth is increased, for example during periods of extreme sunshine or after heavy rainfall or a thunderstorm, we recommend setting the circulation rate to four times a day. Regardless of the circulation rate, we recommend that the system be in operation for at least 8 hours a day to allow for sufficient aeration and filtration.

If all three basic recommendations for the use of UV-C equipment in the pool area are taken into account, the pool can be operated completely without chlorine. If necessary, the selective use of a biological flocculant is recommended. However, our high-quality UV-C lamps allow a combination of chlorine and UV-C, since no ozone is produced, which would be reactive with chlorine.

PURION's high-quality UV-C lamps are long-lasting and very powerful. They produce a very high UV-C content. The lamps we use in the pool area are also used in other systems for drinking water treatment. The UV lamps used do not emit radiation below 250 nm, which excludes the formation of toxic ozone. This means that PURION systems can be used in combination with other treatment processes that use chlorine, for example.

Our compact systems can be operated via regular sockets, which are fused with 10A or 16A as is usual in households. Ideally, these are also protected by a separate FI/LS switch rated at 30mA or better 10mA.

No, in our view, ozone should not be used in pool areas under any circumstances. Ozone is highly toxic. Excess ozone must be destroyed again at great expense, and it is usually unclear how much ozone is left. In addition, ozone reacts with chlorine, so the effect of both processes is greatly reduced. Cheaply produced UV lamps often also emit radiation below 250 nm, which can cause ozone to form. This is excluded with the PURION systems.

Every UV-C lamp has a technically caused drop in UV-C output. The manufacturer guarantees that the system will still achieve 60% UV-C output after 10,000 hours. The data given for the systems also always refer to this 60% output. However, from a running time of 10,000 hours, the drop in output continues to increase. Therefore, the lamp still works, but there is no longer enough UV-C power for an optimal disinfection result.

Lifetime monitoring is recommended for all users who do not leave the system switched on permanently. Replacement of the lamp every 10,000 hours is recommended, as the manufacturer does not guarantee performance beyond this, i.e. the amount of UV-C radiation dose required for safe disinfection.
