Greenheck Introduces Overhead Fans With Northern Light® Technology
December, 2021
Greenheck, the leader in air movement and provider of the most comprehensive selection of products for commercial HVAC systems, announced the incorporation of patented Northern Light® UV-C technology into its line of overhead HVLS fans today. 

“We’re excited to add this technology to our overhead fans,” said Tim Busby, Greenheck general manager— fans. “This applied innovation will truly make a difference in indoor spaces.”

Overhead Fans with Northern Light’s unique, patented design combines the air cleaning benefit of upper-room UV lighting with the air circulation capabilities of overhead fans. Upper-room UV lighting systems (also known as UVGI) have been used for decades to help control airborne pathogens in medical facilities and are recommended by the CDC, ASHRAE, and other organizations as part of a multilayer strategy to reduce the risk of COVID-19 transmission. The addition of air movement has been shown to increase UV-C’s effectiveness. 

With Northern Light technology, non-ozone generating UV-C bulbs are installed inside the fan blades and positioned toward the tips of the blades where the majority of air movement occurs for the most effective inactivation of pathogens. The uplight design directs UV-C light away from occupants and into the upper-room where air is being circulated by the fan, minimizing UV radiation exposure, for safer system operation. The result is a system that is more effective than traditional air cleaning technologies at inactivating airborne pathogens and distributing clean air in occupied spaces.

“Greenheck is taking its overhead fans to new heights by incorporating Northern Light UV-C technology,” added Busby. “Large-scale testing of the Northern Light product has shown increased inactivation of airborne pathogens while the  fan’s air movement increases comfort in commercial, institutional, and industrial buildings.”

Northern Light technology is currently available on model DC-5 overhead fans in four diameters ranging from 6 feet to 16 feet nominally with more models and sizes to be added.
