"Our vision"

With our UV-C – disinfection- and cleaning appliances, we want to contribute to environmental protection and minimise the use of chemical cleaning agents.

Chemical cleaning agents cannot be completely replaced but they can be used sensibly and their use can be reduced by using “environmentally friendly” technology.

We have committed ourselves to UV-C – technology, to enable a reasonable cooperation with our environment also in the future.

The risk of overloading our environment with chemicals is huge!

"Use a spray for something and the job is done ".

"NO"! unfortunately it isn‘t!

One just needs to consider the amount of chemical cleaning agents used to disinfect an “isolated” room in a hospital ward.

Areas of application: Intensive care and isolation wards, as well as in all patient rooms.

Chemical cleaning agents

UV-C – Light

The isolated room must be completely treated with chemical cleaning agents by specially trained staff

The isolated room cannot be used by severely ill patients for a longer period of time.

The patient has to be moved for the period of time in which the room is cleaned and whilst the fumes vapourise.

UV-C – lights are installed in the isolated room. These are used for 60 minutes


After a short time, the patient can return to the room.

The 9 main arguments for Electro-Service-Dönges

UV-C – cleaning appliances


  • there is neither a change of smell nor of taste (when using UV-C devices without OZON)in the rooms to be disinfected or cleaned,
  • by simply exchanging the tubes, you can choose between: in the cleaned and disinfected rooms,

1. UV-C only,

2. UV-C & OZON (ozone forming) and

3. UV-C & OZON (strongly ozone-forming) decide what comes into question for them,

  • no pollution of the environment, since a purely physical application takes place,
  • low maintenance requirement as the parts are easily accessable,
  • little space requirement,
  • ease of use,
  • low usage costs,
  • no danger of under or over dosage,
  • sterilisation of chemically resistant pathogenic agents.

Now a very weighty criterion and clear argument:

The cost factor!

Chemical cleaning agents: when they are used up, they need to be repurchased.

UV-C – lights: one purchase and a small amount of chemicals to disinfect the UV-C lights as a maintenance procedure.

Facit: The UV-C – light solution is, in the long term, considerably more cost efficient, not as personnel intensive and also considerably more environmentally friendly.


Tests have shown that:


Between 99.8 and 100 percent fewer germs, viruses and bacteria!


UV-C radiation is the most effective and smartest way to purify room air - and so easy.


UV-C radiation is like air purification with the power of sunlight.


People recognized the cleansing effect of sunlight early on. I'm sure you all know the clean scent and the wonderful freshness of sun-bleached laundry. The English scientists Downes and Blunt discovered the reason for this particular cleanliness in 1878. They found that microorganisms did not proliferate under the influence of sunlight.


Much later, it was discovered that especially the invisible ultraviolet light in a wavelength range of approx. 253.7 nm has a germicidal effect on bacteria, viruses, spores, yeast and moulds.


Ultraviolet radiation (UV-C) has properties that we only know from chemical or toxic disinfectants. It effectively and safely destroys pathogens. Only with one decisive difference: UV-C radiation, free of harmful substances and ozone! UV-C radiation is the most effective and smartest way to purify room air.


With the following articles and videos, it is not our intention to attack employees of hospitals or similar institutions,

After all, they are the real heroes of daily life.


We want to emphasise that our methods bring substantial advantages to the factors “cost, time and environment”.
