The high volume, low speed (HVLS) fan is designed to circulate the air in your facility more efficiently and effectively.
HVLS fans slowly circulate a large amount of air as the air is pulled from above the fan and pushed down in a conical shape to the floor below. These highly efficient, cost-saving fans are being used in warehouses, distribution centers, gymnasiums and a variety of other applications. Rotating at an optimized low speed, Rite-Hite’s HVLS fans move the most air over the largest area at the lowest cost.
HVLS fans have benefits year-round by creating a more comfortable environment while saving on energy costs. They keep people cool in the summer, and in the winter, they can be used for destratification - a process that mixes warm air from the ceiling with cooler air at the floor.
With the Fan-Commander Touch Screen Control Station, users can optimize the year-round performance of Rite-Hite HVLS fans throughout a single facility, maximizing the energy savings and comfort they deliver.
Motor options: Direct drive or gearbox
Rite-Hite's HVLS fan lineup includes fans with geared motors (Revolution® and the floor-mounted Renegade®) as well as fans with direct drive motors (Revolution 75 Series®and Revolution 25 Series®).
Cost savings at every turn
Costing only a few cents an hour to operate, Rite Hite HVLS fans allow you to save on energy costs by increasing the thermostat temperature while maximizing the comfort level when it’s hot or by warming the facility through destratification when it’s cold. This helps save significant money on energy and heating bills, especially in larger facilities.
Air speed produces a wind chill factor, which lowers the effective temperature, giving a person the sensation of being exposed to a lower temperature than the actual measured/constant temperature. HVLS fans are also an ideal supplement to air conditioning, allowing a facility to raise set points by as much as 4°F (2°C) without a noticeable change in comfort. Increasing set point can help reduce summertime energy consumption by as much as 20%.
The increased air movement caused by our HVLS fan reduces effective temperatures and can help make the air feel up to 18°F (10°C) cooler.
The graphs below show how the "Feels Like" temperature drops with the addition of air movement for an employee working at a high activity level (such as manual lifting, heavy machine or construction work) in three different constant temperature environments. The difference between no air movement and 4 mph airspeeds (with a 70°F constant temperature) can help a worker feel up to 14°F cooler! Source: Thermal Comfort Tool, UC Berkeley
HVLS fans operating in the winter will mix the warmer air at the ceiling with the cooler air at the floor to even the temperature throughout the space (illustrated below). This process, called destratification, can reduce a facility’s energy consumption by up to 30% - meaning typical payback periods for our fans are between 6 months and 2 years.
Rite-Hite HVLS fans provide year-round comfort for employees, customers and other visitors to your facility. In addition to keeping the temperature comfortable, our fans can also help reduce the chance of a heat stress and help eliminate illness associated with “sick” buildings by improving indoor air quality.
HVLS fans can contribute to earning LEED credits in the following categories:
- Energy & Atmosphere
- Indoor Environmental Quality
- Innovation in Design
In addition, many state, federal and local utilities offer rebates and incentives for renewable energy and energy efficiency projects. To learn what is available in your area, visit the US Department of Energy’s Database of State Incentives for Renewables & Efficiency.
Additional Benefits of HVLS Fans
- Reduce condensation on floors (a situation commonly referred to as Sweating Slab Syndrome in the construction industry).
- Eliminate multiple smaller high speed floor or wall fans – A single Revolution Fan can eliminate up to 20 smaller floor fans.
- Eliminate birds from airplane hangars and other large spaces where doors open frequently.
- Prevent expensive metal from rusting due to condensation.
