The best big fans for industrial and commercial use

KHIND Sky Fans
HVLS fans are the most energy-efficient industrial ventilation solution

Energy-saving high-volume low-speed fans are large ceiling fans ranging from 3 (10ft) to 7.3 meters (24ft) in diameter. They are the solution of choice in green buildings due to their dual cooling and heating capabilities, which offer superior ROI surprisingly fast.

HVLS fans are used for heat recovery in Winter, cutting heating costs by up to 45%

HVLS fans are used to cool people and animals in the Summer, reducing the perceived temperature by up to 7°C (12°F), which can reduce air conditioning consumption by up to 30% and in some cases, completely eliminates the need for AC.

Cooling Mode

With the use of large ceiling fans, you are able to achieve a cooling effect of up to -7°C (12º F), and use less energy to cool the area down, resulting in up to 30% savings in HVAC energy.

HVLS fans produce columns of air, which flow down from the fan and then continue to flow horizontally along the floor until the column hits a wall or another fan that carries it further. This increases the air speed at the occupant’s level, making the perceived (feel) temperature much lower than the actual temperature in the building.

This consequently increases convective and evaporative heat loss by the occupant, thus resulting in a cooling effect without changing the dry bulb temperature of the air.

Destratification Mode

Most people who purchase a HVLS fan do so to keep a space cooler. However, big fans can also be a highly effective way to keep your space warmer in the winter and cut your electricity bill by up to 45%.

During winter, hot air rises because it’s less dense than cold air. This process, called convection, creates stratified layers of temperature in which the coldest air stays at the bottom of a room while the warmest air stays near the top.

Vindus Fans disrupt this process with their destratification mode. When this mode is selected, the fans will begin mixing all of the room’s air together. As this happens, warm air that was trapped near the building’s ceiling will be distributed evenly throughout the entire room providing the sensation that you have “turned up the heating”. Not only will this keep your rooms warmer in the winter, but it will also help you avoid heat loss and decrease your building’s energy consumption.
