Fiberglass Fan Blades for Cooling Towers

Swifter CTX Series is intended for cooling towers and heat exchanger fans. With patented airfoils, the fiberglass fans are designed to provide higher efficiency without compromising on fan performance. The airfoils were developed in collaboration with the U.S. Department of Energy’s National Renewable Laboratory (NREL) specifically for industrial cooling towers and heat exchangers. According to the company, they are amongst the highest efficiency airfoils available for these applications.

FRP Fan Blades

Tuf-Lite III was developed from the most severe strength testing program to date at the company. Its one-piece fiberglass-reinforced polyester construction helps ensure good leading and trailing edge protection as well as superior UV protection. The individually balanced, interchangeable blades can be installed in current designs of the company’s hubs. Size ranges from 11 to 14' and 20' to 10 m in diameter.

Motorized Impeller

Model XR combines the efficiency of a backward-curved airfoil impeller with an external rotor motor. Suitable for supply or exhaust applications, the motorized impeller is fully speed controllable. Both motor and impeller are located directly in the airstream, where the impeller acts as a rotating heat sink to ensure heat dissipation and efficient motor cooling.

Sickle-Blade Fan

Sickle Series blades are built for nearly any air-moving application. The sickle blade’s large chord length and thin trailing edge combine to generate greater pressure at slower speeds while significantly reducing noise levels. Available in fiberglass-reinforced nylon, fiberglass-reinforced polypropylene, and aluminum, the fans are offered in diameters from 11 to 77".

Fans for Air-Cooled Heat Exchangers, Cooling Towers

Class 10000 Heavy Duty (HD) fans are designed for large fan diameter installations. Offered in clockwise (RH) and counterclockwise (LH) rotation in fan diameters from 4 to 24" (1.22 to 7.32 m), they can be configured with manually adjustable pitch. Features include a hub tube diameter of 3" for added strength and durability, resilient blade mounts, increased chord width, and adjustable fan diameter (±1.5" [3.81 cm]). The blade angle can be adjusted without removing the fan blades.

Cooling Tower Fan

Marley HP7i fans are designed for cooling tower applications. The Flare Tip blade enhancement increases performance by overcoming tip clearance losses, aiding the movement of air next to the fan cylinder, according to the company. The wide blade design is suited for low noise operation, delivering maximum airflow and pressure capability at reduced speed. Fiberglass reinforced epoxy laminate construction protects against leading edge erosion of the airfoil.

Axial Impellers

Series P2H and P3H utilize blades with an airfoil design. The blade dimension is chosen to provide a uniform air speed over the entire usable blade area. Impeller diameters range from 5.5 to 19.25” with 25° to 50° pitch to suit specific application requirements. The blades are fixed in the hub, ensuring a preset blade angle that cannot move or change under load. The blades are made from high strength, injection-molded thermoplastics or die-cast aluminum.
