Hoenle UVC water disinfection WDS
The Hoenle WDS UVC water disinfection system is a robust and highly efficient solution for the disinfection of drinking and process water as well as for numerous industrial applications. It can be used in a wide range of industries, from domestic drinking water supplies to the chemical and pharmaceutical industries to in-house swimming pools and whirlpools. Those who rely on chemical-free yet powerful water treatment benefit from a technology that leaves the taste, smell and all valuable minerals in the water unchanged. In contrast to other methods, UV-C light enables a very high reduction rate of germs and microorganisms. This effectiveness can be similarly tested, for example, by comparing the principle with [Hoenle UVC air disinfection LQ] in the indoor air sector, which underlines the performance approach of UVC technology.
Powerful disinfection on a physical basis
Disinfection is purely physical, without any chemicals and without changing the pH value or color of the water. This technology reliably neutralizes germs and prevents the formation of unwanted by-products. With a wavelength of 254 nm, the UV-C light is optimally designed to render microorganisms inactive and prevent them from reproducing. Another advantage: the process is tasteless and saves running costs because no consumables such as disinfectant chemicals are required.
The construction made of electropolished stainless steel (usually AISI 316 / V4A) has a high-quality finish and is optimally protected against external influences thanks to the quartz protection tubes. LED indicators for monitoring operation and an easily accessible operating hours counter make maintenance easier. The ballast and control electronics are integrated in a control cabinet to save space, which further reduces installation work.
Important key technical data
- Stainless steel housing (AISI 316 / V4A) for high corrosion resistance
- Flow rates up to 65 m³/h (depending on model)
- Working temperature from 2 °C to 45 °C
- UV-C lamp with a service life of up to 9000 hours
- Mounting position control: working pressure range between 5 and 10 bar
- 230 V ±10 % (50-60 Hz) power supply
- LED indicator lamps for quick function checks
In addition, there is also the option of retrofitting a solenoid valve or thermostat switch if temperature equalization is required. The standard models have various connections from ¼ inch to 4 inch, so that the system can be variably integrated into existing pipes. Thanks to the compact design, simple installation is guaranteed without the need for a direct water shut-off. The removal of individual components (e.g. to replace lamps) can be implemented in just a few steps.
Certifications and standards
The manufacturer produces its UV-C lamps in Europe and undergoes stringent quality tests in accordance with ISO9001. This ensures consistently reliable operation over the entire service life of the emitters. In addition, the device complies with the applicable legal requirements for food irradiation, as no disruptive by-products such as ozone are produced. Particularly in the sensitive area of drinking water treatment, compliance with strict norms and quality standards is essential in order to guarantee safe and flawless disinfection.
Application examples
- Drinking water supply in private households and public facilities: The effective use of UV-C significantly minimizes the risk of bacterial contamination.
- Cold and hot water systems in hotels, spas or wellness areas: without chemical additives, the comfort for guests remains high as neither taste nor smell is affected.
- Process water in production lines (e.g. chemical and pharmaceutical industry): Even with high flow rates, UV-C disinfection ensures microbiological safety.
- Swimming pools and whirlpools in the private and commercial sector: the system significantly reduces the risk of germs, while the water quality and pH value remain stable.
If your business relies on continuous pure or ultra-pure water disinfection, UV-C technology can also help to protect the environment as there is no need for additional disinfection chemicals.
FAQs
How often do the UV-C lamps need to be replaced?
As a rule, the lamps should be replaced after 9000 operating hours. This varies depending on the operating conditions, for example if the water is heavily contaminated or the ambient temperature is extreme.
Does the water need to be pre-filtered?
A pre-filter is recommended if the water has a very high level of turbidity. Clear water conditions increase the efficiency of the UV-C radiation, as suspended particles can weaken the intensity of the radiation.
Do pollutants escape into the water during irradiation?
No, no additional chemical substances enter the water during UV-C treatment. The process is purely physical and does not generate any unwanted by-products such as ozone.
What happens to the minerals in the water
Minerals remain unchanged. The technology relies exclusively on UV light, so the composition of the water is not affected.
Can several devices be connected in series?
Yes, at very high flow rates it is quite common to connect several units. This adds up the capacity without affecting the water quality.
Conclusion
Thanks to reliable disinfection without the use of chemicals, this UVC system offers a safe and economical alternative to conventional methods. Thanks to its high-quality stainless steel housing, long lamp life and ISO9001-certified lamp production, it meets the highest quality standards. At the same time, the purification process is so gentle that the taste, pH value and important minerals in the water remain unchanged. This makes it a durable and environmentally friendly solution for safe water quality in many industries.
