A Pennsylvania facility needed a way to disperse heat generated from the production process and subsequently reduce the temperature on the manufacturing floor. “Increasing the ventilation was the proposed solution,” Dean Scheurich, sales engineer at Coward Environmental Systems, Inc., explains. “We started with reviewing the older manufacturing area’s air exchange rate, then doing calculations on turning over the air in a new section of the plant at a similar rate. We needed more frequent air changes. We had to find a solution to exhaust warm air from the building while also introducing cooler outdoor air.”
After calculating the required amount of air (cfm), the project team determined the air exchange could be achieved by mounting ten UDVL Direct Drive Up Blast Roof Ventilators from Continental Fans at strategic points on the roof. “Each fan can exhaust 40,000 cfm of air. In order to offset the 400,000 cfm of exhaust air from the fans, nine louver/damper assemblies were mounted throughout the plant on exterior walls.”
He adds, “As the temperature rises in the plant, turn the exhaust fans on to discharge the hot air, and open the dampers to pull cooler outdoor air in through the louvers.”
The mechanical contractor determined the roof was too large, and the new fans were heavy, so using a crane to install the fans wasn’t an option. “The fans were set with a helicopter,” says Scheurich. “Utilizing the helicopter also minimizes installation time. All ten CFM fans were lifted individually and set in place in twenty-two minutes. The helicopter definitely reduced time, minimized plant manufacturing shut down, and made the installation easier.”
The Results Were a Breeze
With fans in place and louvers installed, Coward Environmental was able to help the mechanical contractor dramatically reduce temperatures on the manufacturing floor without adding mechanical cooling equipment. “It was a simple solution,” Scheurich says. “CFM manufactures a multitude of fan products, so they were the perfect partner for this project.”
