With heightened vigilance and closer attention paid to hygiene issues as a result of the COVID-19 pandemic, so the requirement increases for decontamination and disinfection – particularly in areas frequented by large numbers of people. As a specialist in decontamination solutions that have proven themselves worldwide in civil defence, disaster control and military operations, Kärcher Futuretech has CBRN decontamination systems and agents for the biological disinfection of people, equipment, vehicles, interiors and infrastructure that can effectively help contain the spread of the virus.

For the disinfection of surfaces and interiors, Kärcher offers the universal, highly effective disinfectant, BDS 2000. It is a combination of the active component Wofasteril SC and the buffer component Alcapur diluted with water. The entire virus spectrum (enveloped + unenveloped), which includes not only influenza but also rota, vaccinia, HIV, BVDV and hepatitis B, is reliably inactivated by BDS 2000 within a few minutes. The disinfectant is best applied in the form of a foam via suitable portable equipment featuring a spray or foam lance, by spray extraction or aerosol application.

DS 5 and DS 10 pressure sprayers (with 5 and 10l capacity respectively) are suitable for surface disinfection. The DS 5 generates working pressure of up to 3 bar using an integrated air pump. The transparent tank makes the filling level easy to read at any time. With its low empty weight of only 2.3 kg, this device is particularly easy and flexible to handle. The stainless-steel DS 10 has an integrated device for mixing of cleaning and decontamination agents and can optionally be equipped with a compressed air connection. With both units, BDS 2000 can be applied as foam to the surface to be disinfected.

The SXM 30 C spray extraction module is also used to spray disinfectant directly onto a contaminated surface. By spraying and simultaneous suction back into the integrated waste water tank, dirt and the adhering dangerous pathogens are completely removed from the surface and simultaneously inactivated by the sprayed-on disinfectant in one step. The SXM 30 C has an area output of 45 m² per hour and can be equipped with three activated carbon filters, which can be very easily replaced and disposed of to prevent carry-over by aerosols.

The mobile HD 5/11 Cage DJ is a compact electric high-pressure washer for the cleaning of surfaces using high- or low-pressure jets at up to 110 bar pressure. It cleans surfaces with cold water and additionally enables the discharge of aqueous disinfectants or cleaning agents based on one or two components, such as BDS 2000 as foam.

The SN 50 Decon thermal aerosol generator is suitable for supportive disinfection of interior rooms, as may be necessary in public facilities. The disinfectant is converted into fine aerosol droplets and a floating mist  created. A disinfectant aerosol generated in this way can thus react with infectious particles in the air and inactivate them. In addition, surface disinfection can be achieved to a limited extent by the slow deposition of the reactive aerosols. Sprayed with a special mist nozzle, even hard-to-reach areas can be disinfected. The SN 50 Decon is compact, self-sufficient due to petrol operation and can be carried and handled by one person.
