HVLS Eco High Volume Low Speed Industrial Ceiling Fan

Whilst HLVS high volume low speed ceiling fans have been around for 10 years the low-energy brushless DC versions of them are relatively recent innovations.  These bring all the benefits of moving a huge amount of air for very low energy use but with the additional benefits that they are easy to install and considerably cheaper to operate, giving even quicker paybacks that can be measured in months.

 

How do HVLS Industrial Fans Work?

 

The principle behind the high volume low speed fan is to move very large volumes of air by the use of large diameter fan blades moving at a slow rotational speed to break up the stratified air layers. The slow rotational speed of the fan makes it far more efficient at converting the electrical energy into useful laminar airflow instead of the wasteful turbulent airflow and drag that occurs at higher speeds – which ends up generating unwanted heat.  These large blades move so much more air than their smaller high-speed compatriot ceiling fans, typically 5-20 times as much, with an equivalent cooling effect.  No other cooling system is as energy efficient as one using HVLS industrial fans. In fact, studies have shown that businesses can lower or even eliminate the use of expensive air conditioning systems altogether with an optimized HVLS ceiling fan solution. Some HVLS vendors offer 3D thermodynamic modeling of their customers’ rooms which proves the efficacy of HVLS fans as highly cost-effective air cooling systems.  This is a bit of a gimmick since if the simple design rules are followed then coverage will be effective.

 

HVLS Ceiling Fan Commercial Applications

 

The range of applications for HVLS industrial ceiling fans is extensive with almost any large room, hall, or building a candidate for substantial operational energy savings.  Putting conventional ceiling fans in these rooms is simply a waste of time and money since the volumes of air that need to be moved and the ceiling height are so big that they make no impact whatsoever at the ground level.  The lack of knowledge about this can be seen in many retail “sheds” that have wasted money on “cheap” ceiling fans that do nothing but waste energy!

 

Typical applications where HVLS fans have been successfully deployed include:

 

• Warehouses and distribution centers
• Vehicle repair workshops & showrooms
• Airports, aircraft hangars, and maintenance facilities
• Agricultural & farm – barns, dairy, poultry, pigs, and equestrian
• Gymnasiums and sports halls
• Shopping centers and large retail stores
• Restaurants and food courts
• Manufacturing, production & assembly plants
• Industrial buildings
• Drying and curing processes
• Paper and cardboard manufacturing plants
• Document stores and warehouses
• Schools and hospitals
• Printing plants
• Fresh food & produce storage and packing sheds
• Museums and exhibition venues
• Transportation stations
• Churches, mosques, and places of worship
