Thermal destratification - not just an after thought

Reznor's Maximisor destratification fans, for exampe, reverse the natural convection process, re-circulating warm air back to working level and providing a permanent reduction in roof space temperature and temperature distribution.

Such fans can reduce a building's running costs as they improve the distribution of warm air making it possible to maintain the required temperature in the working area with fewer warm air heaters.  It is estimated by the Carbon Trust that destratification fans can reduce energy consumption by 20%. In buildings such as warehouses, destratification fans will re-circulate heat generated by machinery, ensuring less energy is consumed by the heating system. This helps prevent hot and cold spots and provides a comfortable working environment. In summer, the fans can be used to provide cool draughts of air.
