SPX Cooling Technologies, Overland Park, Kan., has introduced a new ultra quiet fan for its Marley NC cooling towers. The fan has up to a 12 dBA reduction in sound levels 5' above the fan compared to standard low-sound fans, the company says. The wide-chord blade design delivers good airflow and pressure capability at reduced speeds, SPX says.
Other features include:
- Fire-resistant marine-grade aluminum blades mounted to
the machined aluminum hub.
- Reduced vibration due to the fan being up to 70 percent lighter
than similar FRP fans.
- Lightweight design suited for knockdown towers or tight environments
where cranes and other equipment cannot be used.
- Adjustable pitch by loosening attachment hardware and rotating the blades.
