Fisair, from Physics of Air. Comment on the adsorption process of our systems, without chemical exchange or deliquescence. Unlike the adsorption process, it involves a long product life cycle.


    • 1969, TECNISECO INGENIEROS is founded in Madrid. Its founding partners are the brothers José, Juan and Rafael Boeta.
    • The initial object of the Company is the marketing of steam lance purge equipment and humidifiers. Steam and water filtration equipment is also supplied. This equipment is mainly supplied to the petrochemical industry and nuclear power plants.
    • 1972, the field of air treatment is extended with desiccant rotor air dehumidification.
    • Industrial multinationals found great benefits in controlling the air humidity of their industrial processes. Many companies increased the quality and efficiency of production through a humidity-controlled environment. The quality demands of these companies’ processes made these installations always a challenge. All phases were critical: design, supply and maintenance of humidity control systems and equipment, air humidifiers and dehumidifiers. Thanks to this joint development, the founders of the group to which Fisair belongs, from its Spanish parent company, were able to combine technical rigour with quality and flexibility in each application, each very different from the other.
    • 1975, electric humidification equipment starts to be supplied.
    • Health care and conventional building air conditioning technicians realised the importance of humidity control for air quality and its effects on the human beings who occupy buildings for many hours. It was then that large companies in the air conditioning sector, with no previous experience in air humidity control, contacted our group to jointly develop integrated solutions for their air conditioners.
    • 1994, FISAIR is founded, owned by the Boeta brothers and Pedro R. Ramos. FISAIR’s object is the manufacture of air treatment equipment, especially humidifiers, dehumidifiers, as well as evaporative air coolers and air/air heat exchangers. That same year, the internationalisation of the company began with the design and manufacture of an air dehumidifier for a gelatine drying tunnel destined for Taiwan with a dry air flow of 70,000 m3/h.
    • 1994 – 1997, the first standard series of DFR dehumidifiers and HEF evaporative humidifiers are designed.
    • 1997, begins the design and manufacture of steam injection, generation and dispersion systems, later called the DIPHUSAIR series.
    • 2005, international turnover exceeds domestic turnover.
    • 2012-2013, Pedro R. Ramos leaves the shareholding and the Boeta family takes 100% ownership. There is a change in the management team and a strategic change in the company. Investment in innovation, quality, production efficiency and international expansion is increased.
    • 2014, the first version of the Fisair Selection Tool selection software and the DFRIGO series are launched.
    • 2015, ISO 9001 certification is obtained.
    • 2016, the production area is expanded by 1250 m2 to a total of 4250 m2. The new hall will be used for the production of desiccant rotor air dehumidifiers.
    • 2017, The DFLEX series is launched. Fisair opens subsidiaries in North and South America.
    • 2018, Unification of Tecniseco and Fisair into a single brand to achieve synergies and enhance the best customer service.
    • 2019, Fisair starts operations in the UK through its subsidiary Fisair UK.
    • 2021, Creation of the subsidiaries Fisair USA, Fisair France and Fisair Germany.
    • Creation of Fisair American Manufacturing, an industrial company based in Puebla, Mexico. This plant manages industrial operations for North America, the Caribbean and Central America.
    • 2023, Expansion of the Puebla and Madrid plants to 17,500 m2 to meet the growing demand from different sectors such as energy and automotive.
