Many headlines in recent months and years repeatedly refer to the problem of legionella. These bacteria feel very comfortable especially in hot water circuits, which led to the fact that in some apartments showering was prohibited by the health department. In this situation, which is very annoying for tenants, the PURION 2500 H can provide relief. The landlord is saved a lot of costs if he uses this system instead of heating the water by 20°C to 70°C at extremely high cost. The principle of UV-C disinfection is based on the fact that the DNA of the Legionella bacteria is dissolved and these are killed absolutely reliably. Low energy costs and comparatively low replacement lamp costs are easy on the wallet. Due to the special design, the UV-C lamp of this system can be replaced during operation, although this will rarely be necessary due to its long service life. With a capacity of 5,000 l/h, this UV-C system can also supply larger apartment buildings with legionella-free water without any problems.
Due to a wide voltage ballast, this system is designed for a voltage range of 85-264V and can thus be used in many different countries. The system is equipped with a Euro plug and can also be used with an adapter (not included) for other types of plugs.
The UV-C lamp has a natural power loss over its lifetime. We guarantee that after 8,000 hours the lamp will have reached exactly the promised flow rate. After this time the lamp must be changed, the lamp runtime meter and the lifetime monitoring (OTC) will signal the right time. The hours that the lamp is on are counted and the values are output via an LED display. Up to 9,000 hours a green LED lights up, between 7,000 and 8,000 hours the pre-alarm is indicated by a yellow LED and after 8,000 hours a red LED lights up. Thus, the right time to change the lamp is not missed.
This UV-C disinfection system from PURION meets all the technical requirements of the Drinking Water Ordinance. The used stainless steel 1.4571 is also used in the food industry and therefore meets the standard. In compliance with the prescribed maximum flow rate, the required UV-C dose of 400 J/m² is achieved with a UV-C transmission of 90% T1 cm. This UV-C system thus achieves a disinfection rate of 99.99%, which is required by law. For trademark protection reasons, this system does not have a DVGW certificate, so in individual cases it must be clarified with the health authority whether the UV-C disinfection system can be used.
In addition to the system, this bundle also includes another spare lamp, the matching mounting frame and a service kit for intensive cleaning.
