UV-C Technology

How does disinfection using UV-C work?

Ultraviolet (UV) is electromagnetic radiation that is just outside the area of the light spectrum that is visible to the human eye.

UV-C radiation, with a wavelength ranging from 200 to 280 nanometres, has the most lethal range for micro-organisms. This makes UV-C radiation capable of causing permanent damage to many different undesirable micro-organisms found in water, air or on surfaces. In order for the disinfection process to succeed, each type of micro-organism must be adequately exposed to UV-C radiation. When micro-organisms are directly exposed to the correct intensity of UV-C radiation for long enough the radiation penetrates through the organism’s cell wall. The radiation disrupts the micro-organism’s DNA, so it no longer functions. The reproductive capacity of the micro-organism is damaged or the organism is destroyed entirety.


What value does UV-C add?

Environmentally friendly
UV radiation is environmentally friendly and sterilises without the use of chemicals: toxic chemicals require specialised storage and handling. Since no chemicals are used, overdosing is not possible.

This technology has low initial investment costs and offers reduced operating costs.

Efficient and effective
UV radiation treats water, surface or air immediately and there is no need to have tanks or long retention/lighting times.

UV radiation functions extremely well with other air and water processes, as no changes are made to the taste, smell, pH, conductivity or chemical properties of the air/water in which it is used.

How does UV-C water disinfection work?

Germicidal UV-C systems work by irradiating running water using UV-C light. The lamps are fitted in a treatment chamber, which disinfects the water within a few seconds. 

Can UV-C radiation break down ozone?

Yes, UV-C lamps operating at 254 nm can effectively break down ozone.

How much experience do you have with UV?

We have almost 35 years of experience using UV-C disinfection. Besides that we are a proud member of the IUVA (International Ultraviolet Association). Our membership ensures that we are kept continuously up to date on the latest developments in the field of UV-C. It allows us to develop and improve our systems using the latest techniques and in keeping with safety and efficiency requirements.

Which UV dose do I need?

The size of the UV-system is determined on the basis of 3 factors:

  • Flow rate
  • Lamp power
  • UV transmittance in the water

The UV dose is determined based on customer demand and the above factors. The dose is expressed in mJ/cm².


Which UV-systems does VGE Pro offer?

VGE Pro offers a wide range of UV-systems;

INOX series
The high quality 316L stainless steel reactor of the VGE Pro INOX series have been designed to perform. After the high quality welding process the units are leak tested. After this process they get a pickling and passivation treatment which drastically improves the corrosion resistance and lifetime of the unit. Another last treatment with glass pearls (shot peening) gives the units a nice, matt grey surface.


HDPE series
The high quality HDPE reactors of VGE Pro HDPE series have been designed to treat highly corrosive water. They are suited for all kinds of disinfection and UV-C treatment applications and can even be used for the production of ultrapure water, semiconductor-, pharmaceutical- and cosmetic industry. 


Immersion series
No pressure loss is a great advantage of the VGE Pro Immersion series, because the UV-C lamps are integrated into your water system without a housing. The luminaires are made of high quality stainless steel. The immersion units are designed for a working pressure of 6 bar


Medium pressure series
The medium pressure UV lamps emits a wide spectrum of Ultraviolet (UV) light which not only gives very good disinfection results but is also excellent for photolysis applications like the reduction of chloramine in pool applications.


Air disinfection series
The air disinfection system is designed to safely disinfect air in ventilation systems.


Surface disinfection series
The surface disinfection system is designed to disinfect any kind of surface safe and quick. The handheld is made of stainless steel and is easy to use.

Which UV-systems do I need?

Depending on the area of application and the problem or question, the best UV system for your application is considered. This could be one or maybe several units, but a custom build solution is also possbile. Take a look at our site at the different applications or UV solutions for more information and which UV series are suitable for your application.

How often should UV-C lamps be replaced?

The average effective life of a UV-C lamp is 13.000 hours and 9.000 hours for medium pressure lamps. Although the lamp will still continue to work after this period, its disinfecting value will rapidly decline from then on.


What is VGE Pro?

VGE Pro is the professional disinfection brand of VGE B.V.

VGE B.V. contains three different disinfection brands: VGE Pro (professional), Blue Lagoon (swimming pool and spa) and Xclear (pond).
