According to the German Robert Koch Institute, an infection with Covid-19 via contaminated surfaces is considered possible. US virologists have shown in tests that the novel pathogen Sars-CoV-2 can remain on plastic and stainless steel for up to three days. The Austrian company Amadeo Systems GmbH, developer and supplier of smart access solutions, has developed a door handle which, thanks to oligodynamics, a new coating procedure and the right choice of material, should drastically reduce the risk of smear infection.
Vienna. April 2020. with the touch of a door lever, you inevitably leave bacteria and viruses behind. The next person who touches it absorbs these pathogens through the skin. An unconscious grip on the face and in all probability the infection has already occurred. To eliminate this scenario in the first place, Michael Makivic, founder and owner of the Austrian company Amadeo Systems, has developed a new process that leaves germs and viruses no chance of surviving on the surface.
Oligodynamics is an effect known for over 150 years and describes the damaging effect of metal ions on various pathogenic agents such as bacteria, viruses and fungi. «We have developed a process that uses the effect of oligodynamics. This enables us to create a harder surface for the AMADEO door handle ULC that is free of porous areas, can withstand the demands of everyday life and has a higher antiseptic effect,» explains Makivic. All visible parts of the handle, which is cast in stainless steel, make use of this effect by manufacturing the raw material of the handle from special oligodynamic metals. This is intended to completely prevent the growth of bacteria on the surface. According to Makivic, Amadeo’s new material is many times harder than lacquers or other coatings with which doorknobs have been equipped antibacterially to date.
Door handles with better hygienic properties are needed above all in hospitals, hotels, schools and public buildings and could reduce the risk of infection for patients, employees, guests and visitors in the long term. «However, the best way to avoid a smear infection is and remains touchless access,» says Makivic. For example, the Amadeo lever handle ULC in combination with the Amadeo i-Lock system opens doors for authorised persons autonomously/automatically using an NFC sensor.
In the next step, Amadeo Systems is striving to have the effect of the newly developed method proven by an independent institute. When asked about the exact composition of the new material from Amadeo, Makivic explains: «This remains our corporate secret».
The lever handle is available in the exclusive ULC shape, under service class 4, all visible parts are polished and made of high-quality stainless steel, the handle is cast and polished in high alloy stainless steel and the surfaces are treated with the highest possible antiseptic effect (oligodynamic).
Dimensions of the handle: 22mmx144mmX60mm solid cast iron
Escutcheon rotationally fixed and spring-loaded: DM52 mmx10,9 cast stainless steel with clip-on stainless steel lid.
The mounting is conventional and standardized by 2 pieces M5 Torx screws in 38 mm distance and 8 mm square
