HVLS Fans – High Volume Low Speed

Elite Material Handling Co offers Kelley’s High Volume Low Speed (HVLS) Fans. HVLS fans are designed to provide an energy-efficient solution for large spaces. Using the laws of physics and aerodynamics, HVLS fans require much less energy than traditional HVAC systems, and provide year-round employee comfort and temperature control. The basic scientific principles behind HVLS fans are not new. In fact, many cultures have been using large fans to slowly circulate air for hundreds of years. The simple laws of physics show that a gentle breeze is cooling, and any air speed beyond four or five miles per hour usually offers little, if any, additional cooling benefit. Today, engineers have combined the physics of slow-moving air with complex principles of aerodynamics to create an efficient, economical and environmentally-friendly solution for large spaces – the HVLS fan. These fans move large volumes of air at low speeds over very large areas. The fan blades produce a massive column of air that flows down to the floor and outward in all directions, creating a deep “horizontal floor jet” that ultimately circulates air up vertically and gets drawn back through the top of the fan. The result is more consistent temperature control, improved airflow/circulation and improved energy efficiency. In cooler months, the HVLS fan operates in reverse, circulating hot air trapped at ceiling level and creating a warmer and consistent mix of air throughout the facility (referred to as “destratification”). Main benefits: these fans gently move massive amounts of air to keep people comfortable and productive. A 24’ fan can move air up to 6x its diameter (144’); save energy and money by distributing air – operated slowly, the fan gently pushes warm air down from the ceiling; operated at a faster speed, it creates a cooling breeze over large spaces; can be a showpiece and a way to differentiate a space to gain interest and business; and the fans help with LEED certification and green initiatives
