PDc Personnel Air Shower

Safe disinfection of surfaces with light and dyes

Human risk factor. Humans pose the greatest risk of contamination. 

Conventional personnel air showers are designed exclusively for cleaning off particles and as barrier systems between cleanroom classes. Scientific studies confirm the very low cleaning efficiency of traditional products, techniques and processes from various manufacturers.

PDc technology as an absolute innovation: the Ortner PDc personnel air shower is a highly effective, certified personnel air shower with a JET nozzle technology for physical cleaning of particles and a photodynamic disinfection technique to minimize microbiological contamination.

The new photodynamic technology (PDc) patented by Ortner represents an absolute innovation in the field of safe and effective decontamination of persons. 


Ein großer weißer Schrank, auf dem in blauer Schrift „Turning light into cleanliness“ steht. Die Tür ist komplett aus Glas, hat einen schwarzen Griff und ist geschlossen. Im Türrahmen sind ein roter, ein grüner und ein gelb-roter Knopf. In der Kammer des Schranks sieht man hinten von oben nach unten sechs schwarze runde Kreise. Unter dem ersten ist ein kleiner Bildschirm. Mittig ist wieder ein rot-gelber Knopf. Unter dem obersten Kreis sieht man einen ganz kleinen Bildschirm. Auf der linken Seite in der Kammer sieht man Lichtröhren.
In one chamber you can see the upper left corner of a glass door, the upper right part of the wall with a glass pane installed, and the corner where a narrow ledge is inserted. Behind the glass area in the wall is a switched on light tube. In the narrow bar, are among themselves three black circles, from which white rods come between the top circle and the circle below is a very small screen. The ceiling has frosted glass optics.
Microbiological decontamination and particle cleaning in one process
 A person wearing blue protective clothing, a protective hood and gloves is standing in a shower with his back to the camera. At the persons head level there are black handles that the person is holding on to. To the left and right in front of the person are several lights that are not turned on. On the left between the lights is a red and yellow button.
Sensors monitor the correct position of the person during the decontamination process
Detail of the interior of a chamber. The ceiling is made of frosted glass. On the left and right side of the wall, two fluorescent tubes can be seen. Between the two fluorescent tubes, a short black rod is attached at the top. In the left and right rear corners, a black circle can be seen, from which a short white rod looks out.
The JET nozzle pulse system generates targeted vibrations on the textile and optimizes particle cleaning

Proven Highest Possible Decontamination of the Personnel in the Clothed State

All Ortner Personnel Airlocks are designed for reproducible processes.

The nozzle technology used was developed on the basis of the simulation results of an air flow and particle transport as part of an extensive research, working in cooperation with Graz University Research Center of Technology to ensure efficient particle removal.

With the aid of the patented photodynamic technology, it is possible not only to remove particles but also to reduce microbiological germs on the surfaces.

Effective Disinfection of Cleanroom Clothing

 A woman stands in a chamber. There is a closed glass door on the back wall. The woman is dressed in a blue protective suit and wears a protective hood, cap and gloves in white. She has both her arms raised above her head and is holding on with her hands to black rods coming out of the side walls to her left and right. On the left edge of the chamber go from top to bottom evenly distributed several small black circles, from which comes a small white rod.
Microbiological germ reduction up to 98%.

Our PDc Technology has a Very Positive Response on the Market

"In the research area at the German Heart Center Munich, we have relied on Ortner's photodynamic decontamination technology for several years. By using PDc clothing in combination with the PDc personal air shower, personnel can be effectively decontaminated while clothed. After work, the clothing is placed in the PDc wardrobe, decontaminated and ready for repeated use. This system eliminates the need for disposable clothing and constant changes of clothing. The added benefit is that the special PDc garments are comfortable to wear compared to other RR protective suits."

"Im Forschungsbereich am Deutschen Herzzentrum München vertrauen wir seit mehreren Jahren auf die photodynamische Dekontaminationstechnologie der Firma Ortner. Durch die Verwendung von PDc-Kleidung in Kombination mit der PDc-Personenluftdusche kann das Personal in bekleidetem Zustand effektiv dekontaminiert werden. Nach der Arbeit wird die Kleidung im PDc-Garderobeschrank abgelegt, dekontaminiert und ist somit zur wiederholten Verwendung bereit. Dieses System erspart die Verwendung von Einwegkleidung und ständigen Kleidungswechsel. Der zusätzliche Vorteil: Die spezielle PDc-Kleidung bietet im Vergleich zu anderen RR-Schützanzügen einen hohen Tragekomfort."
