Destratification

In the winter, large facilities with high ceilings share one thing in common - they are expensive to heat. The method of heating may vary but the common factor with any heating system is that heated air rises to the highest point and is then lost through the ceiling. The heaters are now heating the top two thirds of the building, working overtime to force heat down to the floor and at thermostat level.

Because heat rises, a situation called 'stratification' occurs. It is common in any large structure with an average insulated roof to see a temperature difference of 10°-20°F (6°-11°C) or higher from floor to ceiling. However, by thoroughly mixing or 'destratifying' the air, High Volume Low Speed (HVLS) fans also known as destratification fans, can virtually eliminate this temperature differential.

Destratification Fans are huge downdraught fans ranging from 8 feet to 24 feet in diameter. They offer an inexpensive and efficient way to bring the heat down from the ceiling to mix with cooler floor temperature air, ensuring a consistent and comfortable temperature where it is most needed. This results in significant energy savings. In some cases it has created savings as much as 30 percent.**

In the summer, air conditioning relies on expensive electricity to operate. Destratification fans can work in conjunction with air conditioned spaces. Operating the fans on slow speeds creates a constant moving mass of air. This allows for a higher temperature set point and reduces compressor run time. Alternatively, destratification fans provide an efficient and cost effective way to cool environments where air conditioning is not feasible.  The fans also reduce humidity, which makes it more comfortable for the occupants.

Destratification fans can be applied in various applications - manufacturing, commercial, industrial, agricultural, recreational facilities, warehouses, malls and aviation hangars, to name a few.

In new construction, destratification fans can eliminate the need for expensive duct work for both heating and air conditioning systems.

Benefits

• Works along side your existing HVAC systems
• Simple to install and runs with minimal operating costs
• Provides a consistent even temperature from floor to ceiling and wall to wall
• Quiet and efficient operation
• Minimizes the amount of warm air that has to be continuously replaced with cold outside air to achieve adequate ventilation
• Generally improves air quality when used in conjunction with any make up air system by assuring a good air mixture and diluting stale contaminated air
• Provides a comfortable workplace and increases productivity
• Constant summer airflow lowers humidity which will eliminate condensation, mold growth, wet floors and corrugated box and container degradation
