DESTRATIFICATION AUTHOR Joe Petrie DESTRATIFICATION FANS OFFER Small Solutions to THE MASSIVE size of hangars and terminals can mean massive costs and issues when it comes to keeping a comfortable climate for employees and travelers. But before you look at costly HVAC system upgrades to meet these demands, you may want to consider destratification fan systems (DFS). " This continual airflow creates a current within the air space. Once that current is established, it requires very little energy to maintain, " said Joel Sasso, president of DRD Systems, a supplier of DFS units. " This is how our system saves energy/money for our customers, while increasing the air quality and overall comfort for their customers and employees. " Destratification means removing the separated temperature layers from the air within an enclosed space and equalizing the temperature from ceiling to floor. The traditional method of attempting to equalize temperature uses a ceiling fan or HVLS fan - both of which spin paddles/blades, creating a turbulent flow of air. A destratification fan converts all that rotational flow/energy into Laminar flow, creating a narrow/tight column of air which flows continually. Airports with high ceilings can take stress of the HVAC system using a destratification fans. They equalize the temperature within the facility, which makes it easier to maintain a specific climate. Gama Aviation at Farnborough Airport was experiencing high energy costs inside its main engineering hangar. Airports with high ceilings can take stress of the HVAC system using destratification fans. DRD SYSTEMS Destratification fan systems (DFS) can improve the overall environment in a facility without the need for costly HVAC upgrades. DRD SYSTEMS 22 \ AIRPORTBUSINESS / SEPTEMBER/OCTOBER 2021
