Daikin VRV and Daikin Altherma are the most sold heat pump systems in Europe, with over 500,000 systems delivered to date.

Streamer & Coronavirus Technology

Daikin confirms the effectiveness of patented streamer technology, which successfully deactivated more than 99.9% of the new coronavirus (SARS-CoV-2) after irradiating the virus for 3 hours.

The study was conducted by Daikin Industries Ltd in collaboration with Professor Shigeru Kyuwa of the Department of Biomedical Sciences at the University of Tokyo and a research team led by Professor Shigeru Morikawa of the Department of Microbiology at Okayama University.

Experimental Results

The research team conducted an experiment where the viruses were irradiated for 3 hours with Daikin Flash Streamer technology.

The results of this experiment showed that:

Flash Streamer discharge deactivated 93.65% of coronavirus (SAR-CoV-2) after 1 hour irradiation time

Flash Streamer Discharge Disabled 99.97% of Coronavirus (SAR-CoV-2) After 3 Hour Irradiation Time

The tests described here only apply to patented Streamer technology. The effects of products equipped with Streamer technology or the effects on the actual user interface may differ. For more information on Daikin products that incorporate Streamer technology, see the related product information.

About Streamer Technology

Streamer technology, developed by Daikin in 2004, performs an oxidative decomposition of harmful substances. The Streamer discharge is a type of plasma discharge featuring an innovative air purification technology that stably generates high-speed electrons.

Its oxidative decomposition capability is much higher than the conventional plasma discharge (glow discharge). Moreover, when combined with air components, these high-speed electrons have a capability for powerful oxidative decomposition that continuously remove odours, bacteria and indoor air pollutants such as formaldehyde.
