Daikin Industries Ltd was founded in 1924 as Ōsaka Metalworking Industries LP (大阪金属工業所, Ōsaka Kinzoku Kōgyōsho) by Akira Yamada. In 1953, Daiflon or polychlorotrifluoroethylene was developed. In 1963 the company was renamed Daikin Industries, Ltd. (ダイキン工業株式会社, Daikin Kōgyō Kabushiki-Kaisha; Daikin deriving from the combined reading of the first kanji of 大阪 Ōsaka and the first of 金属 Kinzoku) and developed Neoflon. In 1982 it was renamed to the current Daikin Industries Ltd.

Daikin entered the North American air conditioning market in 2004.[7]

In 2006, Daikin Industries acquired McQuay International, a Minneapolis, Minnesota–based global corporation that designs, manufacturers and sells commercial, industrial and institutional heating, ventilation and air conditioning (HVAC) products.[8] In 2008, McQuay International was rebranded as Daikin-McQuay as Daikin began implementing many of its technologies (including the Daikin Inverter Compressor) and manufacturing processes into McQuay equipment and factories. However, in November 2013, the Daikin-McQuay group was again rebranded as Daikin Applied,[9] ending 80 years of business for the McQuay name in the United States. Meanwhile, the McQuay brand continues to be used in mainland China and Hong Kong.[10]

In the filtration realm, Daikin acquired American Air Filter (AAF) in 2007,[11] and Flanders in 2016.[12] The resulting entity is known both as AAF International and AAF Flanders.

In 2008, Daikin purchased a 75% share of All World Machinery Supply based in Roscoe, Illinois.[13] In 2009, Daikin Airconditioning Philippines was established.[14]

In August 2012 Daikin agreed to acquire Goodman Global from the San Francisco–based private equity firm Hellman & Friedman for $3.7 billion,[15] after first planning to buy Goodman the previous year. In January 2011, Daikin had announced plans to buy Goodman Global at approximately US$4 billion valuation;[16] however, the plans were delayed for a year by the 2011 Tōhoku earthquake and tsunami.[17]

The acquisition was expected to expand Daikin's presence in the United States and in duct-type and split-system air-conditioners, and was expected to make Daikin the world's largest maker of heating, ventilation and air-conditioning systems.[18][needs update][19]

Later in 2013, they launched a split air conditioner, the Ururu Sarara FTXZ-N.[20]

As of April 2014, Daikin Hydraulics marketed a line of piston pumps, vane pumps, manual pumps, solenoid valves, and flow and control valves, claiming their pump technology to be 50–70 percent more energy efficient than conventional technology.

In 2017, Daikin opened the Daikin Texas Technology Park, its largest plant and the fifth largest factory in the world. Costing $417 million, this 4.1-million-square-foot facility in Waller, Texas, will consolidate Goodman's manufacturing operations.[21][22]

As of 2021, other companies representing additional Daikin brands include Motili and Quietflex.[23]

On March 2, 2023, Daikin announced they had acquired the San Diego–based custom air-handling equipment manufacturer Alliance Air Products.[24]

In 2024, Daikin bought the naming rights to Minute Maid Park, home of Major League Baseball's Houston Astros, renaming it to Daikin Park on January 1, 2025. The deal is expected to run through 2039.[25]

On February 27, 2025, Daikin announced that the company will stop producing white phosphorus shells.[26]

Centennial celebration

[edit]

On April 28, 2024, Daikin Philippines President Takayoshi Miki hosted Daikin's first fun run, “Daikin: Run for Clean Air 2024” at Bridgetowne with 800 runners.[27] On May 21, 2024, Daikin Industries, led by President & CEO, Masanori Togawa with Chief global group officer and board chair, Noriyuk Inhoue, celebrated its centennial founding with a commemorative ceremony attended by 2,000 at The Symphony Hall to further support its "Forests for the Air" project.[28]

PFAS pollution and lawsuits

[edit]

In 2005, Daikin and 3M paid $4 million in a US settlement over water contamination with perfluorinated compounds in Decatur, Alabama, the site of several chemical production facilities.[29] In 2017 Daikin agreed to pay $5 million to the West Morgan-East Lawrence authority for an advanced water purification filter. The authority had advised residents not to drink the water in 2016 due to PFAS contamination.[30] In 2021 Daikin, 3M, Toray, BFI Waste Systems, and Synagro paid a $98.5 million settlement with the city of Decatur over PFAS dumping in Morgan County.[31]

A 2004 study by Kyoto University Professor Akio Koizumi identified Daikin as the source of PFOA pollution in the Yodo river.[32][33] In 2020 a Settsu city survey in Osaka found elevated levels of PFAS contamination in groundwater and waterways. One well used to irrigate crops was found to have levels 420 times over the national average. In 2021 blood tests of 9 residents living near Daikin's Yodogawa factory revealed elevated levels of PFAS, the highest in a 69-year old man 70 times the national average.[34] Daikin had suspended production of PFAS-based water repellents in 2012 and stated the risks were “only possibly carcinogenic, like how pickled vegetables are” and that the water in Daikin's wastewater treatment tanks as "clean enough to drink" at a city council meeting. Daikin later issued retractions towards the "clean enough to drink" statement. [35] Production and export of perfluorinated compounds in Japan have been banned since 2021.[36]

History

Origins and Pre-War Development (1924-1945)

Daikin Industries originated on October 25, 1924, when engineer Akira Yamada established Osaka Kinzoku Kogyosho Limited Partnership (OKK) in Osaka, Japan, as a small factory employing about 15 people. The company initially specialized in manufacturing radiator tubes for aircraft, capitalizing on Japan's growing aviation sector during the interwar period.[30][3] By 1929, OKK expanded its product line to include the Rational lubricator, a device for oil distribution in machinery, reflecting early diversification beyond pure aircraft components. In 1933, amid Japan's military buildup, the firm initiated research into fluorine-based refrigerants, shifting toward chemical engineering applications. This groundwork culminated in 1934 with the incorporation of Osaka Kinzoku Kogyo Co., Ltd., complete with a corporate symbol, and the successful trial production and subsequent manufacturing of the methyl chloride-based Mifujirator refrigerator. The following year, 1935, OKK achieved a national milestone by producing fluorocarbon gas for the first time in Japan, with mass production scaling up by 1942.[3][31] The late 1930s saw OKK apply its refrigeration expertise to transportation and military needs. In 1936, the Mifujirator was installed as Japan's inaugural train air conditioner for Nankai Railways, while production of oil hydraulic parts for aircraft commenced, aligning with escalating defense demands. The Sakai Plant opened in 1937 in Osaka to support growing operations. By 1938, OKK delivered a fluorocarbon-equipped Mifujirator refrigeration unit for Japanese Navy submarines, underscoring its role in wartime technology. Plant expansion continued with the 1941 establishment of the Yodogawa Plant in what is now Settsu, Osaka, as the company contributed to military production amid World War II, including designated supplier status for the Navy since 1931.[3][32][31]

Post-War Recovery and Initial Commercialization (1946-1970)

Following Japan's defeat in World War II, Osaka Kinzoku Kogyo Co. (OKK), the predecessor to Daikin Industries, faced severe operational disruptions, including the cessation of military production and the layoff of most of its approximately 16,500 employees in August 1945.[13] To survive, the company repurposed leftover materials to manufacture civilian goods such as pots, pans, and furniture by late 1945.[13] The Yodogawa Plant was requisitioned by U.S. Occupation Forces in October 1945 but returned in July 1946 after OKK fulfilled orders for fluorocarbon 12 refrigerant.[13] U.S. military contracts provided critical revenue, including orders for fluorocarbon 12 in March 1946 and refrigerators delivered in April 1946, enabling initial stabilization.[13] Domestic production of ice-making machines began with deliveries in August 1946, followed by refrigerator sales to the Japanese market in June 1949.[13] However, challenges persisted, including hyperinflation, canceled U.S. orders in June 1949, and successive layoffs—200 employees in 1948, 267 in September 1949, and 250 in 1950—reducing the workforce to 438 by April 1950.[13] Financial oversight by banks from 1949 to 1953 further constrained operations, yet under founder Akira Yamada's leadership, the company prioritized technological adaptation for civilian needs.[13] Pivoting to refrigeration and air conditioning marked OKK's path to commercialization. In May 1951, the company developed Japan's first packaged air conditioner, the "Mifujirator," simplifying installation compared to prior systems requiring specialized expertise.[33] [31] This was followed by applications in marine vessels, such as installations on the Tonan Maru in 1951 and Brazil Maru in 1954.[13] Fluorochemical advancements bolstered these efforts: production of anhydrous hydrofluoric acid started in 1954, Daiflon (PCTFE) in 1953, and Polyflon (PTFE) in 1955, with exports of fluorocarbons commencing in 1958.[31] [13] By the late 1950s, OKK expanded residential offerings with Japan's first window-type air conditioner in 1958, equipped with a rotary compressor, and began exporting air conditioners in 1954.[31] [13] Semi-hermetic compressors introduced in 1953 enhanced refrigeration efficiency.[13] These developments, driven by figures like director Minoru Yamada—who emphasized employment stability—laid the foundation for OKK's transition to a commercial focus, culminating in the adoption of the Daikin brand for fluorochemicals in 1963.[13]

International Expansion and Diversification (1971-2000)

In 1972, Daikin established Daikin Europe N.V. in Ostend, Belgium, as its first European subsidiary dedicated to air conditioner production and sales, with knockdown assembly operations commencing the following year to serve the growing demand in Western Europe.[34] This marked the onset of Daikin's targeted international expansion beyond Japan, leveraging its expertise in split-type air conditioning systems amid rising energy efficiency needs post-1973 oil crisis. Concurrently, the company diversified its portfolio by advancing fluorochemical applications, building on earlier developments like the 1970 DAI-EL fluoroelastomer, which expanded into seals and gaskets for industrial uses.[34] The 1980s saw accelerated diversification and geographic outreach, with Daikin launching A.C.E. Daikin (Singapore) Pte., Ltd. in 1980 for regional manufacturing and sales, followed by Siam Daikin Sales Co., Ltd. in Bangkok, Thailand, in 1982.[34] That same year, the introduction of the VRV (Variable Refrigerant Volume) system—a multi-split air conditioning technology with a single outdoor unit—revolutionized commercial applications and bolstered export competitiveness, enabling Daikin to penetrate markets requiring zoned climate control.[35] Further subsidiaries included Daikin Airconditioning (Hong Kong) Ltd. in 1984 and Daikin Airconditioning (Thailand) Ltd. in Chonburi in 1987, shifting from export reliance to localized production to mitigate currency fluctuations and tariffs. Daikin's fluorochemicals segment also grew, with increased production of polytetrafluoroethylene (PTFE) and other polymers for electronics and automotive sectors, diversifying revenue streams away from pure air conditioning dependency.[34][36] By the 1990s, Daikin intensified operations in emerging Asian markets and North America, establishing Daikin Industries (Thailand) Ltd. in 1990 with air conditioner production starting in 1991, and venturing into China via Shanghai Daikin Yah Chong Airconditioning Co., Ltd. in 1995 as a joint venture for commercial units.[34] Additional expansions included compressor manufacturing in Xi'an, China (1996), and sales arms in Malaysia, France (1993), the Philippines (1998), South Africa (1998), Austria (1999), and India and Spain (2000). In the United States, Daikin America, Inc., and MDA Manufacturing, Inc., were founded in 1991 to produce and sell fluorocarbon polymers, with factory operations online by 1994, reflecting a strategic pivot to chemicals amid maturing domestic AC markets.[34] This period solidified Daikin's dual-pillar model—air conditioning and fluorochemicals—accounting for balanced revenue growth, with overseas sales rising from negligible shares in the 1970s to over 20% by 2000 through localized facilities and technology transfers.[37]

Residents near Daikin's Decatur, Alabama facility filed lawsuits in 2020 against Daikin America, Inc., alongside 3M and Toray, accusing the companies of releasing PFAS into the Tennessee River, leading to contamination of local water supplies and potential health risks.[146] Alabama water authorities similarly sued Daikin America in related actions, seeking remediation for PFAS discharges from the plant, which has been cited for elevated emissions in environmental reports.[147] In March 2023, the city of Lyon, France, initiated legal proceedings against Daikin to investigate the scope and duration of PFAS emissions from its operations, amid broader European scrutiny of fluorochemical producers.[148] Further escalating PFAS-related legal actions in France, Daikin Chemical France's facility in Pierre-Bénite (near Lyon) has been implicated alongside Arkema in significant discharges of PFAS into the Rhône River. The site, operational since 2002 producing fluoroelastomers, has contributed to cumulative releases of dozens of metric tons of PFAS over decades. Contamination levels have been alarmingly high, with one surface water sample measuring 273,992 ng/L, impacting downstream water supplies serving hundreds of thousands of people, as well as food chains and public health—evidenced by elevated PFAS levels in blood and breast milk affecting over 200,000 residents in the region. In January 2026, 192 local residents filed a major civil lawsuit against Daikin and Arkema in the Lyon judicial court, seeking more than €36 million in damages for alleged health and environmental harm caused by these "forever chemicals." Cleanup costs for the contaminated area have been estimated at up to €2 billion. This case, one of Europe's largest civil PFAS lawsuits, has been highlighted by the Forever Pollution Project and various media investigations, underscoring ongoing concerns about persistent emissions from fluorochemical production.[149][150][151] Daikin America achieved a complete dismissal of PFAS-related tort claims in 2025 via a unanimous ruling from the Supreme Court of Alabama, which granted mandamus relief and rejected arguments for liability in groundwater contamination cases tied to its fluoropolymer production.[140] Regulatory bodies have imposed ongoing obligations; for instance, the U.S. Environmental Protection Agency's multi-industry PFAS study under the Toxic Substances Control Act has scrutinized Daikin's fluoropolymer manufacturing for potential releases and exposures.[142] In Europe, proposed REACH restrictions on PFAS groups target uses in sectors where Daikin operates, including refrigerants and coatings, prompting compliance reviews but no Daikin-specific fines to date.[152] Beyond environmental matters, Daikin faced U.S. Occupational Safety and Health Administration (OSHA) penalties in 2022 totaling $232,103 after two workers died and a third was hospitalized from exposure to toxic gas (HFC-23) at its Decatur plant in 2021; citations included one willful violation for failing to monitor air quality and provide adequate protective equipment.[153] The U.S. Department of Labor's Office of Federal Contract Compliance Programs entered a 2023 conciliation agreement with Daikin Industries after finding violations of Executive Order 11246, prohibiting discrimination by federal contractors, requiring enhanced affirmative action and training without admitting fault.[154] Product liability suits have also arisen, including a 2025 class action alleging Daikin Comfort Technologies knowingly sold defective Amana air conditioning units prone to capacitor failures, leading to premature breakdowns and repair costs.[155] In Nemirovsky v. Daikin North America (2021), a Massachusetts jury initially held Daikin liable for intentional misrepresentation and breach of implied warranty in supplying faulty HVAC coils, though subsequent appeals partially vacated the judgment against the company.[156] Courts dismissed related environmental claims in PAWS Holdings v. Daikin Industries (2020), rejecting negligence allegations over greenhouse gas leaks from HVAC units.[157] Smaller regulatory settlements include a $5,365 civil penalty with California's Air Resources Board in 2021 for emissions reporting discrepancies.[158]

In March 2025, Daikin Industries was selected for the second consecutive year to the "Innovation Momentum 2025: The Global Top 100" by Frost & Sullivan, recognizing companies for their innovative practices in research and development, intellectual property generation, and market impact.[109] Earlier, in March 2024, the company received inclusion in the inaugural "Innovation Momentum 2024: The Global Top 100" for similar criteria, highlighting its advancements in HVAC technologies.[177] Additionally, in March 2025, Daikin was named among the Clarivate Top 100 Global Innovators 2025, an accolade from Clarivate Plc evaluating patent filings, citations, and global influence in innovation.[178] On the sustainability front, Daikin earned placement on the CDP Climate Change A List in July 2025, awarded by the non-profit CDP for superior disclosure and performance in emissions management, based on verified data submitted through their global disclosure system.[179] In October 2025, Daikin Europe and Takenaka Europe jointly received the PLGBC Green Building Award 2025 in the Sustainable Industrial Building category from the Polish Green Building Council for their heat pump production facility in Wronki, Poland, commended for energy-efficient design, low-carbon materials, and biodiversity integration.[180] The company's Daikin ATMOSPHERA air conditioner series, utilizing R-32 refrigerant, was honored with the 2024 SEAL Sustainable Product Award by the Sustainability, Energy & Leadership Awards program for reducing environmental impact through lower global warming potential refrigerants and efficient operation.[181] Daikin has also secured Science Based Targets initiative (SBTi) validation for its greenhouse gas reduction goals aligned with a 1.5°C pathway, as detailed in its 2025 Sustainability Report, reflecting commitments to net-zero emissions by 2050 across scopes 1, 2, and 3.[182] In 2025, its Decatur, Alabama facility attained Silver status under the Daikin Green Heart Factory system, a proprietary framework assessing resource efficiency, waste reduction, and renewable energy use, positioning it as the top performer among North American Daikin sites.[183] These recognitions underscore Daikin's focus on verifiable metrics like emissions cuts—achieving a 27% reduction in net GHG emissions in FY2024 against baseline projections—and lifecycle assessments in product design.[184]

Ongoing Industry Adaptations

Daikin continues to adapt to stringent global refrigerant phase-down mandates, such as the EU F-gas Regulation revisions and the Kigali Amendment to the Montreal Protocol, by prioritizing the widespread adoption of R-32, a mildly flammable hydrofluorocarbon with a GWP of 675—substantially lower than R-410A's 2,088.[185][186] This shift enables up to 12% greater cooling efficiency and 18% higher heating efficiency in systems like the Daikin ATMOSPHERA compared to legacy R-410A units, while reducing overall refrigerant charge volumes and leakage risks through design optimizations.[187] Daikin argues that pure R-32 outperforms blended alternatives like R-454B in real-world direct emissions, despite equivalent GWP thresholds under regulations like California's CARB rules, emphasizing lifecycle efficiency over nominal GWP metrics alone.[188][189] To address electrification and building decarbonization trends, Daikin is enhancing heat pump portfolios, including the fourth-generation Altherma series for monobloc air-to-water applications and CO2-based VRV systems for commercial use, both unveiled at ISH 2025 in Frankfurt.[190][191] These adaptations support energy resilience amid rising demand from AI data centers and policy incentives like California's heat pump acceleration goals, with Daikin committing to market growth through efficient, low-carbon HVAC deployments.[192][193] Concurrently, upgrades to self-contained systems like the SWP J-Vintage model integrate low-GWP refrigerants with advanced controls for cost-effective decarbonization in existing buildings.[194] In parallel with HVAC shifts, Daikin is responding to PFAS scrutiny by investing over $300 million in wastewater treatment to capture fluorochemical discharges, achieving internal targets for emission reductions while maintaining production of enabling materials like refrigerants.[193][132] The company phased out PFOA manufacturing group-wide by 2015, two years ahead of global deadlines, and continues R&D into safer fluorinated alternatives to balance regulatory pressures with performance needs in high-demand sectors.[143] These efforts, detailed in Daikin's 2025 Integrated Report, underscore a multi-pronged strategy toward net-zero compatibility, including refrigerant recovery enhancements and application-specific low-GWP developments.[195][196]
