Benefits of Ceiling Fans

          

Like human beings, animals and poultry suffer in hot stagnant air.  It provides a living hotbed for harmful bacteria.  Ceiling fans can circulate and disperse air up to a

tremendous 43,500 CFM , creating a mild windchill that cools the animals and poultry.  Continuous air movement speeds drying of floors, bedding, walls and ceilings. 

Seasonal condensation problems are drastically reduced making for a safer working environment, such as eliminating slippery floors by dispersment of moisture. 

The result?  A healthier, cooler environment for animal, poultry and people, resulting in higher production and comfort for all.

Hot air rises causing very definite temperature differences at various room levels.  In heated buildings, there can be a 15 to 25 degree difference from colder floor to hotter ceiling.  The ceiling fan, at efficient lower speeds, forces the stratified, heated upper air down.  By equalizing the overall temperature in a building, thermostats can be lowered where the air at body level will remain warm.  The result?  Your bills will drop as much as 30% (and sometimes even more).

The cost of running these ceiling fans is usually small; one fan uses less energy than a 100 watt light bulb.  With increasing fuel costs and world demand for energy, the ceiling fan system makes sound operating sense.  Besides costing little to operate, it uses existing heating and cooling systems to bring more efficient, effective solutions to current and future poultry care problems.

Some houses have been a problem to ventilate under cold winter conditions in the past.  Ceiling fans can ventilate certain houses although the houses are not completely air tight.  Air exchange is dependent upon outside wind velocity and direction.  Leakage around the curtain can provide sufficient air intake.  Ceiling insulation is crucial if low volume ceiling fans are used.  Winter ventilation requires only minimal air exchange of one-fourth to two CFM per bird.  Initial cost of the fans will run about three cents per bird and operating costs add on less than one-half cent per bird for a hundred day period under most conditions.  With insulated ceilings and low volume fans, certain wall poultry houses can be winter ventilated and still maintain higher temperatures and good air quality.

Ceiling fans are easy to install from ceiling beams or cross braces.  Solid State infinite speed controls may also be used to give ultimate control over the speed on the fans from 1-300 RPM.

The usage and success of the operation of ceiling fans is no better than the operators.  Common sense must be used to successfully operate the ceiling fans.  On low speeds ceiling fans reclaim hot air trapped at the ceiling and keep it from seeping through the roof.  The fans push the air down and around in a circular column and spread it evenly throughout the room.  Cold spots and drafts can be eliminated.  You can turn the thermostat down six to eight degrees and be just as warm as before and cut the heating bills. 

There are many other types of usage for the ceiling fans other than poultry buildings, such as:  Auditoriums; Bowling Lanes; Automobile Service Centers; Warehouses; Churches; Boat and Auto Show Rooms; Banks; Factories; Department Stores; Barber Shops; Restaurants; Bars; Retail Shops; and Schools and Gymnasiums.
