Daikin is committed to “Perfect the Air” develop air conditioning innovation for health with the launch of Daikin’s patented Streamer technology deactivate SARS-CoV-2 virus deliver pure, clean air to consumers


Mr. Akihisa Yokoyama, President of Siam Daikin Sales Co., Ltd., the world’s leader in air conditioning technology, reveals that Daikin has employed a strategy to create and develop air conditioning systems that “perfect the air” to deliver pure and clean air to consumers. The improved products would feature innovations for health and hygiene to accommodate the current SARS-CoV-2 pandemic that forces consumers to adopt New Normal lifestyle and look for health-improving devices and tools.

Daikin is delighted to announce the technology that fills this consumer’s need. The Daikin patented Streamer technology has been verified of its efficacy of successfully intercepting SARS-CoV-2 by The University of Tokyo and Okayama University of Science in Japan.

The test was completed scientifically and concluded that, when Streamer was turned on for 3 hours, it has the ability to deactivate 99.9% of SARS-CoV-2 virus and MHV-A59, and 93.6% of SARS-CoV-2 virus and 91.8% of MHV-A59 after 1 hour. However, the rest was conducted in a lab with a Streamer discharger and the efficacy is not inclusive when the technology is used in the actual environment.

To further ensure the consumers in Thailand, Daikin has collaborated with Environment Engineering Department, Faculty of Engineering of King Mongkut's University of Technology Thonburi to verify the efficacy of Streamer technology in ZETAS air conditioner, launched earlier in Thailand. ZETAS is the first Daikin air condition launched in Thailand with Streamer technology, which was previously launched in air purifier.

The test simulated actual consumer’s home environment in Thailand to make sure that the local climate will not affect or diminish the efficacy of Streamer technology. The test result shows that Streamer technology can deactivate 75 - 99.96% of virus, bacteria and fungus in the air conditioner unit in the first 8 hours of use and 99.9% of pathogens in the fourth day. It is confirmed that Streamer technology can deactivate virus, bacteria, fungus, allergens and harmful gases in the air.

Mr. Akihisa Yokoyama says that Daikin tested the technology with respected institute to ensure the Thai consumers of its validity and strengthen Daikin’s position as the air expertise company. Daikin will continue to test Streamer technology’s efficacy with more renowned institutions in Thailand to confirm the results.

Test results from The University of Tokyo and Okayama University of Science in Japan, as well as King Mongkut's University of Technology Thonburi show that Streamer technology embedded in Daikin air conditioner and air purifier has the ability to deactivate SARS-CoV-2 and reduce foul odor from bacteria and fungus in the air conditioner.

Mr. Akihisa Yokoyama continues that Daikin has been working closely with leading universities and state research institutes to test Streamer technology with harmful matters such as H5N1 virus, H1N1 Norovirus, harmful substances and bacteria that causes food poisoning. Streamer technology has also been tested against 60 harmful matters, which include 7 bacteria, 30 allergens and 19 dangerous chemicals and its efficacy was confirmed by a state research institute.

The streamer technology has been developed by Daikin Industries (Japan). In 2004, the technology was launched in the market with its highlight feature, the streamer discharge, that is capable of dissolving harmful substances in the air.

Streamer discharge is an air purifying technology that creates stable high-speed electrons – a technology that was hard to achieve at that time. Streamer’s ability to decompose matters with oxidation is higher than glow discharge. Moreover, when combined with the air’s molecule, these high-speed electrons can decompose matters with oxidation, allowing streamers to eliminate unpleasant orders, bacteria, and pollutants such as formaldehyde continuously and effectively.

This technology sets a new benchmark for household air conditioner and strengthens Daikin’s philosophy of not only cooling down the temperature but also perfecting the air. It also elevates the standard of air conditioner industry and inspires manufacturers to further develop technologies to the new height and deliver quality products with advanced technology to the consumers.
