Heavy Duty Fans

What Heavy Duty Fans does

HDF s.r.l. (Heavy Duty Fans) is an Italian designer and manufacturer of custom heavy-duty industrial centrifugal and axial fans, founded in 1993 and headquartered between its registered office in Sondrio and its production facility in Brugherio. The company targets industrial operators in steel, cement, chemical processing, power generation, marine, mining, and infrastructure, engineering fans for low, medium, and high-pressure applications and delivering custom solutions where standard products are unsuitable. Products are qualified against AMCA, API, DIN, ISO, and GOST standards, and the company holds ISO 9001 certification while pursuing ISO 14001 and ISO 45001.

The core product portfolio spans low- to high-pressure centrifugal fans, axial fans, and related accessories, with simulation-driven design executed on ANSYS Mechanical CFD since mid-2016. R&D is supported by a collaboration with CNR (IPCB and INSEAN institutes) and was capitalized by a €1,995k Lombardy R&D grant awarded in 2020. The business model is direct enterprise sales of custom equipment, supplemented by spare parts, installation, commissioning, and testing services, with a small channel layer of appointed sales agencies in Spain and Belgium/Luxembourg. The company is a private limited company (s.r.l.) with 11-50 employees, and its scale positions it as a mid-sized niche specialist within a fragmented European industrial fan market.
