Howden PRO D-Series 26'-36' (7.93M-10.98M) Fans

The Howden PRO D-Series 26′-36′ (7.93M-10.98M) cooling tower fans are highly efficient cooling fans which combine the highest aerodynamic performance with very low power consumption.

Standard Features Include:

  • Straight aerofoil design – the D-Series fan rotates clockwise in the horizontal plane
  • 20ºC to 65ºC operation – the D-Series fan works in hot and cool industrial environments
  • Polyurethane-coated steel hub – the D-Series fan also has aluminum blade supports and stainless steel U-bolts, nuts and washers

Optional Features Include:

  • Up to 120ºC operation – with special modifications, the D-Series fan can operate in temperatures above the 65ºC standard limit
  • Upgraded Leading Edge blade protection – we can better protect the blade for use in wet cooling applications
  • Upgraded materials and coating – we can upgrade the D-Series fan so that it’s appropriate for sea water cooling tower applications
  • Coupling flanges – we can supply cast iron, polyurethane-coated coupling flanges to mate with drive shafts having either a cylindrical bore or a tapered bushing connection
  • Blades: FRP (Pultruded Fiberglass)
  • Blade Supports: Aluminum
  • Hub: Polyurethane Coated Steel
  • U-bolts: Stainless Steel
  • Fasteners: Stainless Steel

Pro D-Series – 26′ – 36′ | 5 – 8 Blades

  • DNF: Classic fan featuring Howden Aerotip technology
  • DLF: Low-Noise
  • DVF: Extra Low-Noise

Product description

The Howden Pro D-Series 26′-36′ (7.93M-10.98M) cooling tower fans are highly-efficient cooling fans which combine the highest aerodynamic performance with very low power consumption.

  • 9 – 11 Blades
  • Delivers high efficiency and reduces power consumption
  • Boosts cooling performance designed to deliver the optimum aerodynamic performance
  • Damps down mechanical vibrations the FRP blades offer superior damping of mechanical vibrations and great chemical resistance
  • Durability and longevity the fan blade is integrated (rather than bolted on) to the shaft, reducing mechanical stress at the joints
  • Simple to assemble – D-series fans come with clear technical documentation
  • Applications – Field-erected cooling towers, air-cooled condensers (ACC)
