Stratification is caused by hot air rising to the ceiling or roof space because it is lighter than the surrounding cooler air. Destratification gathers the trapped warmer air and redirects it strategically to where it is needed in order to reduce the temperature differential from floor to ceiling. In a stratified building, temperature differentials of up to 34°F (1.5°C) per vertical foot are common and the higher a building's ceiling, the more extreme these temperature differentials can be. The most effective and easiest to install technologies to address these temperature differentials are destratification fans, including both axial destratification fans and HVLS fans.
Every application is unique and in order to design the best solution for each, we need to know details about what you are trying to accomplish. Fill out a quote request and set up a site visit so we can help you develop a proper solution.
All models of the open ceiling fans feature a standalone axial destratification fan powered by highly energy efficient EC Fans and Drives, LLC motors. These fans are built to be suspended just below ceiling height in your building and the speed which the fan is set is dependent upon how high up the fans are located. This series is suitable for buildings with a ceiling height of up to 40’ as they push air down in a column no wider than 2’ to 3’ without a spread that interferes with people below. The square fans are common in warehouse applications, while the round fans were developed in answer to customer demand for a more sophisticated retail aesthetic.
Flush mount ceiling designed destratification fans are built to be dropped into a traditional grid or suspended ceiling. The fan is completely self-contained (no duct attachments) and fits into standard 2x2 ceiling grid systems. These fans push trapped air to the floor which evens temperatures building-wide and provides additional air circulation as well as cooling or heat recovery.
