Boldrocchi - Centrifugal Fans
We’ve been engineering and manufacturing centrifugal fans for over 100 years and we’ve grown the product line through acquisition. Our goal? Continue to have more expertise than anyone else in the market. We’ve created over 30 main centrifugal fan designs yet customize each one for every customer. Our expert team will design the optimal combination of materials, blade design, impeller size, etc., so that your objectives are met or surpassed. We can engineer and manufacture our centrifugal (radial) fans to operate with nearly every process condition, in any type of application across a multitude of industries.
- Flow rates up to 2,500,000 m3/hr (1,470,000 ft3/min)
- Installed power up to 10 MW (13,000 hp)
- Tip speeds over 220 m/sec (720 fps)
- Special blades design, such as air foil profile, to ensure extreme efficiency and low power absorption, as well as specialty fans such as for chlorine processing and steam compression
- High yield materials including S690QL, ASTM 514
- Corrosion resistant materials including stainless steels, duplex steel, titanium, Inconel, Hastelloy, etc.
- Special liners & coatings, including hard rubber liners and glass flake coating
- Wear resistant materials including Creusabro®, Vautid®, chromium carbide & tungsten carbide plates
