Air Movement, Humidity and Temperature Control
High-Volume, low-speed fans (HVLS) have become the standard for low-cost, high efficiency environmental control in a wide variety of commercial and industrial settings. Moving large volumes of air down from the ceiling and across the floor of a building creates a more comfortable, safe, and productive work environment while improving temperature control year round.
In a building, humidity can be one of the biggest challenges faced every day. In 2010, the U.S. Environmental Protection Agency (EPA) estimated that indoor air pollution, which can be caused by humidity, costs businesses $93 (€84.5) billion, with a productivity loss of $73-87 (€66-79) billion.
Sweating Slab Syndrome (SSS) is when moisture intermittently develops on the surface of an interior concrete slab, such as a warehouse floor. SSS can increase the slickness of the concrete surface and pose a serious risk to the safety of workers and materials handling operations.
Studies show that as temperatures go up, productivity drops with just a few degrees of temperature difference having a positive (the cooler it is) or negative (the warmer it is) impact. Add humidity into the equation and the comfort level of a building can change dramatically. With air speeds of just 2-3 miles per hour (3-5 km/h), an HVLS fan can affect a 7 to 11 (4-6 °C) degree drop in temperature.
Sick Building Syndrome (SBS) is a term used to describe situations where building occupants experience acute health and comfort issues that appear to be linked to time spent in a building, even though specific causes can’t be identified. Stagnant air, humidity, or lack thereof, can be primary contributors of SBS. By increasing air movement, HVLS fans can help dissipate moisture and disperse concentrations of airborne contaminants.
Product integrity is paramount to the bottom line. The impact of humidity or excess moisture on equipment and inventory can result in substantial product loss or manufacturing downtime. HVAC systems control temperature, but increased airflow is key to controlling condensation and corrosion.
The Rite Solution. We offer a variety of HVLS fans to address environmental control issues and provide an alternative to other, less effective floor fans. A single fan can cover areas up to 22,000 square feet (2043 m²) and can replace as many as 10 to 20 floor fans, or smaller ceiling fans. With something for every situation and need, Rite-Hite manufactures four-blade and two-blade fans, as well as a floor mounted model.
