Information about the MDG16-1

mobile disinfector


"the driveable"


Since UV-C light only develops its full power on surfaces and in the room air, the combination of UV-C light and OZON is required to disinfect a room completely.


The MDG16-1 is available for 3 different disinfection applications:


  1. Version 1, only with UV-C light, the surface and room air are cleaned. With this application, the room or workplace can be used again immediately.


  1. Version 2, with UV-C/OZON - tubes ozone-forming, here the surface, the room air, as well as places, which the UV-C - light does not reach, are disinfected, thus also behind freely standing devices and objects. With this application a ventilation after the application is urgently to be recommended.


  1. Version 3, with UV-C/OZON - tubes strongly ozone-forming, here is, like with 2. a ventilation after the application compellingly necessary, since the OZON formation is still stronger, like with operation 2.


With all 3 versions with the MDG16-1, nobody should be in the room to be disinfected.


The application time is approx. 20 minutes!

(This time can also be set individually by us, depending on the customer's wishes).


With application 1. the room can be used again immediately after the application.


With application 2. and 3. the rooms should only be entered again when the OZON-containing air has been "degraded" again.


A commercially available fan is recommended for this purpose.


The 9 most important arguments for

clean & healthy

disinfection & cleaning

with UV-C & OZON


UV-C - disinfection and cleaning devices.


  1. there is no change in smell or taste (when using UV-C devices without OZON) in the rooms to be disinfected or cleaned,


  1. by simply exchanging the tubes, you can choose between:

1. only UV-C, 2. UV-C & OZON (ozone-forming) and 3. UV-C & OZON (strongly ozone-forming) decide which application is particularly suitable for you.


  1. no pollution of the environment, since a purely physical application takes place,


  1. Low maintenance requirements, as all parts are easily accessible,


  1. low space requirement,


  1. easy operation,


  1. low operating costs


  1. no danger of under- or overdosage,


  1. Disinfection especially of chemically resistant pathogens.


For all applications,

"take urgent care of your safety".


We would be pleased to prepare for you, Before - After - Test with test reports, which are evaluated by renowned German microbiological laboratories and according to international standards.


Upon request, we will gladly send you convincing and meaningful test results.


Also we can show you with Quick test, on-site an evaluation of the cleaning carried out by them so far and which "impact" the disinfection reaches by the MDG16-1.


Disinfection with the MDG16-1 takes only a short time and does not harm our environment!


If you request us, call us, or send us an e-mail, we will reply immediately.


The MDG16-1 has an infinite range of applications,

here are just a few suggestions for you


- doctor's surgeries and retirement homes -


- Camping sites and camper vans -


- Military -


- Red Cross and Technical Relief Organisation -


- Home care -


- Hotel´s and pensions -


- Hospitals and rehabilitation clinics -


- Food production - Bakeries -


- Food production - Butcher's shops -


- Schools and children's garden -


- Livestock breeding and keeping -


What cannot be "reached" with the MDG16-1 (e.g. in kitchens, bathrooms or toilets),

This is what our handy MDG15-1 is designed for.

In our planning is a "new device", the MDG19-2,

which is built like the MDG16-1, but has smaller dimensions.



Technical details:


The development concerns the mobile disinfection unit MDG16-1, for chemical-free sterilisation, sterilisation and disinfection of all surfaces and room air, particularly suitable in the above-mentioned "areas of application".


The MDG16-1, consists of high quality parts.


In the "lamp body" are the 8 ballasts and the holders of the 8 UV-C - tubes.


The 8 UV-C tubes have a wavelength of 253.7 nm (nm = nanometer).


The total consumption of the MDG16-1, with an output of 8 UV-C tubes of 36 W/h each, is approx. 388 W/h. Compared to other processes, it is environmentally friendly and economical in operation, as no chemicals are used.


The stand with its 5 castors is tilt proof and thanks to its "span" of approximately 65 cm suitable to fit through any standard door.


The two aluminium tubes supplied are 2 x 1,000 mm long and twist securely, the "lamp" is attached to these aluminium tubes.


The lower aluminium tube is screwed into the tube holder of the mobile stand by means of a knurled nut.

The MDG16-1 has an approx. 10 meter connection cable, depending on customer requirements, it can also be supplied in other lengths.


In the lower "part" of the MDG16-1, the electrical connections and operating elements are located.


The MDG16-1, is easy to operate and equipped with high-quality built-in devices that comply with the latest technology and standards.



For more details, please refer to the instructions for use and safety,

that come with every MDG16-1.



KBE (colony-forming units)


KBE is the abbreviation for "colony-forming units". The English name is "Colony Forming Units", abbreviated CFU.


A colony-forming unit is a microorganism that is capable of reproducing and that leads to the formation of a single colony during cultivation. If a solution containing microorganisms is applied to a nutrient medium, the microorganisms multiply and visible accumulations (colonies) are formed. By counting the colonies, the microorganism content of a sample is determined. Ideally, the number of colonies is equal to the number of microorganisms contained in the sample. In fact, however, some individuals often lie so close together that they form a colony. In this case, the sample contains more microorganisms than the number of colonies would mean. For this reason, the concept of colony-forming units was introduced, which includes both single individuals and individuals attached to each other.


CFUs are a decisive criterion for the quality of pharmaceutical water as well as in clean rooms in medical and pharmaceutical areas. There, there are limit values for microbiological contamination prescribed especially for the rooms in the GMP guideline EG-Annex 1, which are collected and documented by air samples, sedimentation plates and contact plates.


Clean room class Recommended limit values for microbiological contamination












duplicating plates

(RODAC), are

used by us.



- Guidance on the level of contamination -


Within the framework of hygienic microbiological tests, the VDI guideline is applied to germ count.









The following bacterial count data can therefore be used as a guide for the degree of condamination, for example, in surgical departments:
