UV Filter / UV Light for Water NORDIC TEC UV 55W-PH
UV water filter UV light for water - complete set with a power of 55 W
with PHILIPS brand filament
One of the most frequently chosen biological UV filters or UV lights for water based on ultraviolet radiation for single-family homes (the second most popular device is the 30W version). The 55W UV light for water is an excellent choice if you have water from your own well or if the water supply network is contaminated, such as with E. Coli bacteria. This size is ideally suited for home water purification, demonstrating effectiveness of up to 99.3% in removing bacteria, fungi, and viruses. It works well not only in homes with a traditional layout (kitchen + bathroom) but also in homes with two bathrooms.
Kit details - UV Light for water 55W:
- The main element is the so-called reaction chamber, i.e. a steel tube made of S304 stainless steel with dimensions of 975 x ⌀64mm
- It has a glass quartz tube to protect the filament
- Included 55W filament - easily accessible in case of replacement: model PHILIPS TUV 55W G55 T8, with an expected lifetime of up to 10,000 hours
- Connections with a diameter of 3/4 "
- Nominal flow at the level of 2.65 m3/h for the dose of UVC 300 J / m²
(or for UVC 400 J/m² - 1,85 m3/h)
- The most common application - an apartment / house for 2-5 people
Information about the selection is indicative, it does not take into account any additional factors of water consumption, such as watering livestock, watering plants or additional bathrooms.
Contact us if you need the help with sizing the UV light.
- Working pressure up to 10 bar (definitely allows for use in domestic and industrial conditions)
- Wall brackets and sealing O-rings included
- Power supply / transformer adapted to work on 220-240V / 50-60Hz, with a grounding cable included in the set - EU PLUG
- The power supply has a LED indication of the operation of the filament and the lack of operation of the filament (i.e. the need to replace the filament)
Direct contact with UV rays for the eyes is dangerous
Do not turn on the lamp when it is outside the so-called reaction chamber
Does the UV light for water treatment operate continuously or only when water flows?
For a UV light for water treatment - 55W, continuous operation is recommended:
- The 55W UV filter (or any other power) should operate continuously, i.e., 24/7, to provide an uninterrupted barrier against E. Coli and similar biological contaminants.
- It is not recommended to frequently turn off the UV sterilizer for short periods, such as when leaving for work or overnight. The 55W UV filter should only be turned off if the building will be unoccupied for longer than 1-2 days (e.g., weekend or vacation trips).
- Philips UV bulbs for water sterilization are designed for continuous (including multi-month) operation. This is not harmful to the bulb or other elements of our UV systems.
- It is advised against synchronizing the lamp with water flow (e.g., with a pressure tank). Such water sterilization is ineffective (as there is no UV barrier most of the time) and additionally leads to premature bulb damage. If you choose to sterilize water with a UV lamp, it's important to remember this aspect.

Important information and instructions for installing the UV water filter
There are some important tips to consider - as many installers try to assemble the UV water filter themselves, without the involvement of a plumber. Especially that not every plumber has experience in connecting a UV lamp and proper care. Naturally, caution is advised - for an obvious reason, the UV water filter contains glass elements.
- The first important tip is to install it in a place that will guarantee access to the lamp in order to replace the possible filament replacement (statistically, we replace the filament once a year, sometimes less often, if we travel frequently)
- The UV water filter, so the UV lamp - can be mounted both horizontally and vertically, depending on your convenience. However, it is worth plugging it into the installation with the use of rigid pipes, not hoses. It should be firmly mounted on the wall, which will not be provided only by the handles in the set - especially when we additionally burden the lamp with unnecessarily flexible hoses.
- We do not turn on the filament when it is outside the reaction chamber and do not look directly into the UV light, nor touch the active filament with our fingers. Generally, we avoid the exposure of the skin or eyes to UV radiation, as it is harmful to living tissues (on this principle it eliminates microorganisms). So we turn on the filament when it is inside the steel chamber, the instruction describes how to check if the filament is working. Additionally, the power supply has a LED indication of the filament operation.
- The glass part of the UVC filament should not be touched with your fingers, the filament should be grasped by the tips if possible. If there are fingerprints on the filament, it may burn out immediately after turning it on (a similar reaction as in the case of a car bulb touched before installation).
- Before installation, it is worth cleaning the filament and the quartz tube with a cloth soaked in alcohol. It is absolutely necessary if there is dust or fingerprints on these glass elements, especially the filament is sensitive.
- After installing the UV water filter, it is worth running the water for 1-2 minutes, without turning the lamp on to electricity. This will remove any dust residues that could be in the steel chamber.
- There should be mechanical filters in front of the UV water filter. In most cases - the lamp is mounted behind the pre-filters at the entrance to the house, which does the trick. The water must, however, be clear, free of mechanical impurities.
- Before and after the UV water filter - it is recommended to install shut-off valves. This will allow for possible service activities, such as replacing the filament, without draining the water from the installation, but only by cutting the UV water filter from the installation. An alternative route may also be considered, so that in the event of a longer service, run the water via an alternative route and cut off the lamp until it is restarted.
