XL-UV series Disinfection/Sterilizer Units for potable and non potable water. Main feature this serie is units are able to treat large water flow-rates, while remaining compact in size due to powerful lamps. Every system is able to treat huge flow rate with a few lamps φρομ 1 το 4.
UV-C also provides a photochemical degradation effect. In addition, RXL-UV systems are particularly suitable for swimming pool applications, since they reduce the high combined chlorine concentration, which is the major cause of irritation and unpleasant odour.
The efficiency of ADTEC medium pressure equipment is guaranteed with few lamps being used, and it is used for applications in which large volumes of water also have to be treated (e.g. water supplies, post-disinfection of waste water, etc.).
In addition, they are particularly suitable for swimming pool applications, since they reduce the high combined chlorine concentration, which is the major cause of irritation and unpleasant odour.
On request we can supply with automatic cleaning system (wiper) of the quartzes.
Compatible with all other water processes (i.e., RO, filtration, ion exchange, etc.).
RXL.675 (67.5 KW)
*For bigger flow rates are available units with 7.5 kW lamps. Contact our offices for more information.
Method of operation
Η Ultraviolet light is electromagnetic radiation with wavelengths shorter than visible light. UV can be separated into various ranges, with short range UV (UVC) considered “germicidal UV.”
At certain wavelengths UV is mutagenic to bacteria, viruses and other micro-organisms. At a wavelength of 2,537 Angstroms (254 nm) UV will break the molecular bonds within micro-organismal DNA, producing thymine dimers in their DNA thereby destroying them, rendering them harmless or prohibiting growth and reproduction.
It is a process similar to the UV effect of longer wavelengths (UVB) on humans, such as sunburn or sun glare.Micro-organisms have less protection from UV and cannot survive prolonged exposure to it.
Ultraviolet disinfection of water consists of a purely physical, chemical-free process. UV-C radiation attacks the vital DNA of the bacteria directly. The bacteria lose their reproductive capability and are destroyed. Even parasites such as Cryptosporidia or Giardia, which are extremely resistant to chemical disinfectants, are efficiently reduced.
A UVGI system is designed to expose environments such as water tanks, sealed rooms and forced air systems to germicidal UV. Exposure comes from germicidal lamps that emit germicidal UV electromagnetic radiation at the correct wavelength, thus irradiating the environment. The forced flow of air or water through this environment ensures the exposure.
A key factor of UV water treatment too proper choose a model is the flow rate: if the flow is too high, water will pass through without enough UV exposure. If the flow is too low, heat may build up and damage the UV lamp.
