RockTenn of Jacksonville, FL was looking to replace their rooftop exhaust fans with a more effective, more reliable solution. The plant engineer said he was looking for something new because “the motor-driven fans were a maintenance headache.” He added, “they were hard to get at, some had belts, and some were direct drive.”

Installing the maintenance free GreenRoo units solved this problem overnight. Made of high-quality aluminum, and set in a premium bearing, the GreenRoo turbine vents spin with just the slightest breeze. The high-quality materials ensure they unit won’t rust or seize even under the worst conditions.

The GreenRoo units replaced the roof fans that were previously on the building. At 5 hp each, at a rate of $600/hp/year, the cost of running the fans was about $70,000 a year. This expense disappeared with this improvement. As the motors in the building’s remaining fans out, they replaced them with GreenRoo ventilators. To date the plant has cooled about 75,000 ft2 of their building space using by using GreenRoo turbine vents.
