Larger saltwater pools up to 50m³ can be cleaned with a PURION 2501 P in an ecologically safe way. In order to take full advantage of the health benefits of a saltwater pool, cleaning must also be based on health aspects. The classic variant of pool cleaning with chlorine contradicts this insight, because the advantages that a salt water pool has for the skin are cancelled out by the disadvantages of chlorine. In contrast, the PURION 2501 P cleans with the help of the UV-C disinfection process. In this process, the pool water is irradiated with UV-C, which dissolves the DNA compounds of bacteria and algae. As a result, the saltwater pool remains free of algae and can become an oasis of well-being. The PURION 2501 P does not change the taste or smell of the water. Unlike cleaning with chlorine, the composition of the water is not changed. A saltwater pool should be cared for with the same care that you give yourself when you buy one.

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

Due to the PVC choke, the device is also suitable for salt water. Since the welding seams of stainless steel are attacked by the salt, there is no alternative to PVC for salt water.

In order to keep a pool permanently free of algae, the correct coordination between pump and UV-C system is necessary. The rule is that at least three times the pool content flows through the UV-C system during the day. The maximum flow rate of 14m³/h should not be exceeded, otherwise the water will not be disinfected properly. In certain cases it is necessary to let the system run longer: This is urgently required, for example, after heavy rainfall or if the water has stood in the basin over the winter.

If the initial situation is unfavorable with a lot of algae, it may be advantageous to use a biological flocculant to support the UV-C system.

Häufig gestellte Fragen

Can this system overheat?

The Purion's pool systems are not exposed to overheating problem if the UVC system should be switched on, but no water flow takes place.

Does the system automatically switch on the water flow?

No. We recommend that the UV system always put the UV system into operation in combination with the pump, which uses the full flow for disinfection. Since the system has a relative large diameter, there is no failure, the pump should be defective and this does not lead to water flow when the UV lamp is switched.

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

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. The circulation rate is therefore based on the respective performance of the pump used and sand filter. The net performance of the pump can be reduced by cable lengths and heights to be overcome.
Also interesting: In our compact systems, the pump, sand filter and UVC system are ideally coordinated and already pre -assembled.

How long does the system have to run to keep a pool with algae?

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.

Is chlorine also required for pool cleaning?

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.

What distinguishes Purion's UV-C systems?

The high-quality UV-C lamps of the Purion brand 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 Purion systems can be used in combination with other preparation procedures that e.g. chlorine.

Do you recommend the use of ozone?

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 excluded from the Purion 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.
