HOW THEY WORK
Stratification occurs because air from a heater, which is approximately 5-7% lighter than cool air, tends to rise to the ceiling. In the winter, Big Ass Fans are slowed, not reversed, to efficiently destratify heat, slowly moving large volumes of warm air off the ceiling without creating a draft. The steady mixing of air creates a uniform temperature throughout the space, which helps the heater maintain the same thermostat setpoint with less effort, resulting in a serious reduction of operating costs – over 30% in some cases! Providing a quick return on investment is more than enough to make you feel all warm and cozy inside.
Creating and maintaining consistent temperatures from ceiling to floor and wall to door can also reduce condensation and its buddy, corrosion, as well as mitigate mold
Fans, which span up to 24 feet (7.3m) in diameter, move air throughout the entire space, from ceiling to floor and wall to wall, including up and over obstructions such as machinery and stacked product. This airflow pattern ensures air reaches all corners of the building, maintaining consistent conditions throughout and eliminating condensation and stagnant areas where product integrity is a concern.
The natural process of thermal stratification occurs in all buildings; it results in dramatic differences in temperature from floor to ceiling. Thermal stratification is caused by hot air rising up to the ceiling or roof space because it is lighter than the surrounding cooler air. Conversely, cool air falls to the floor as it is heavier than the surrounding warmer air. This means that heating and cooling systems have to constantly cycle on in order to maintain building interiors at a set and even temperature throughout.
Heating and cooling systems are typically over-delivering to compensate for this stratification phenomenon in an attempt to achieve a required temperature at working/operating level, which is normally only around 1.5 metres to 2 metres from the floor. This costs a lot of money and creates a lot of carbon.
