Core offering

Fisair designs, manufactures, and sells industrial air humidity control equipment under three product lines: DF series desiccant rotor dehumidifiers, DIPHUSAIR steam and isothermal humidifiers, and HEF evaporative coolers. The company serves industrial B2B customers in energy (wind turbines), lithium-ion battery manufacturing, pharmaceuticals, food processing, data centers, museums, and military/defense applications with custom-configured equipment and supporting technical services including installation, commissioning, spare parts, and remote monitoring (telecare).

Product overview

Fisair is a specialist provider of industrial air humidity control systems, operating as a unified product portfolio across three core product lines. The DIPHUSAIR line comprises six distinct steam and electrode humidifier variants (FSH, MT2, Electrode, Resistance, ASC, VxV) for adding moisture to air. The DF line is the largest portfolio with ten dehumidifier models (DFA, DFOG, DFRA, DFLEX, DFLOW, DFRB, DFRC, DFRD, DFRIGO, DFRM) plus DFC condensation units, covering desiccant rotor technology, dual-rotor heat recovery, and cold storage applications. The HEF line offers four evaporative cooling solutions (HEF2E, HEF3-CAD, HEF7, AtomSpray) with hygiene-certified contact panel technology. Together, these products serve industrial applications across energy, food, pharmaceutical, data centers, and lithium-ion battery manufacturing sectors, with over 15,000 machines operating globally.
