Ceiling fans are widely used for air circulation in the commercial, industrial and agriculture industries. The ceiling circulating fan is an efficient and effective way to circulate air, or stir stale and stagnant air in your building or facility. Typical applications for these fans are gyms, food service, warehouses, factories, barns, dairies, workshops, halls, churches or any where air movement is needed.
Many of these fans can run both forward or reverse to help assist you heating and cooling systems. So you can push heated air down from the ceiling where it tends to gather during the winter months to reduce heating bills, or pull hot air up to the ceiling and then out through the ceiling vents in the summer to reduce cooling bills.
Though the ceiling fan does help in reducing heating ans cooling costs, the real benefit is that they can recirculate the air causing a more comfortable and productive work environment.
ASSISTANCE IN HEATING
The effectiveness of a ceiling fan air circulation system for heating your facility during the Winter months is based on a simple concept called heat stratification. Heat stratification within a closed space is where heavier cold air drops to floor level, while lighter warm air rises to the ceiling or highest point. As a result, the air temperature can increase about .75 of one degree per foot from floor level to the ceiling. This difference can be even greater when there is production process heat or halogen type lighting in the room.
Consider a room with a 15' ceiling and no ceiling fans. The temperature might be set at 68 degrees at thermostat level (approx. 5' above the floor), but would be only 64 degrees at floor level and 76 degrees at the ceiling. The floor level where people or workers are located would be cold and drafty, while the ceiling level would be hot, stuffy and potentially humid as well. The thermostat would then be turned up higher than 68 degrees to maintain an actual 68 degrees comfort for the people at floor level. The room (at floor level) would keep requiring more heat, even though the ceiling was already filled with wasted inaccessible heat.
Ceiling fans can help equalize a rooms temperature by pushing or forcing down and mixing the heated ceiling air with the cooler air below. The thermostat stays at its original setting for longer periods of time, and can be set at the actual desired temperature level. workers will be more comfortable and productive. In buildings with high ceilings (15 feet or higher), thermostats can be cut 5-10 degrees after installing a proper ceiling fan system, yet floor temperatures will still increase.
Here’s the best news; statistics from the utility industry show that the resulting reduction in heating costs can be as much as 30%. For every one degree the ceiling temperature is lowered (by destratifying heat with ceiling fans), there can be a 3% savings in energy costs. This makes the fan system more of an investment than a cost.
ASSISTANCE IN COOLING
During the Summer months a ceiling fan system can substantially save you in cooling costs by adding an evaporative cooling affect, air circulation, thus creating a uniformly comfortable temperature to the work environment.
When ceiling circulator fans are used along with air conditioning, tests from ASHRAE have shown that a thermostat setting can be raised by as much as 8 degrees without loss of employee comfort when ceiling fans are running. The breezes created by these fans provide an evaporative cooling affect that lowers skin temperature by up to 7 degrees. This increased air movement provides an effective temperature of 72 degrees when the thermostat is set at 80 degrees. Every degree you raise your thermostat in summer can save you 3% - 5% in air conditioning costs.
Circulating Fans can also eliminate cold areas and dead air pockets by stirring the stale or stagnant surrounding atmosphere. Cooled air is continuously recycled. Thermostats stay at their desired temperatures for a longer period, reducing the air conditioning system's load and its operating expense. Ceiling fans running continuously can also help to reduce the build-up of ceiling heat, which helps to prevent the air conditioning thermostat to shut off sooner during the cooler times of the day. Total energy savings of up to 50% can be achieved.

The ceiling fans vertical air circulation speeds evaporation of moisture in all seasons, and helps prevent mold and mildew issues. It can also prohibit condensation build-up that results from day and night temperature differences, when heat is stratified at the ceiling level.
There are several styles and sizes of ceiling mounted fans. Industrial Fans Direct offers a large selection of propeller type fans with blade sizes from 36" to 24' - suspended mount drum fan up to 48" blade size, and beam mount ceiling drum fan. The air movement rating for these fans range from 7,000 CFM to 100,000 + CFM. Keep your buildings' temperature more evenly regulated, and help make employees more comfortable and productive by installing a ceiling fan or multiple fans depending on the size of the facility.
