Air handling units


With energy consumption a continuous battleground for building and facilities managers and contractors tasked with reducing emissions, the effective use of destratification is an opportunity that cannot be missed


technology’s low energy usage, small upfront cost and reduced heating bills investment pay back periods are typically under two years. The Centre for Advanced Energy Systems at Rutgers University in the U.S. examined 700 projects designed to “improve air circulation with destratification” under the U.S. Department of Energy and The Energy Efficiency and Renewable Energy Industrial Technology Program found an average payback period of 1.6 years.


Non-invasive installation


The installation of destratification fans is also a lot less invasive than traditional air movement methods. Using a simple cable and grip method, the fans can be fitted in minutes and the self-contained design means that the fan won’t interfere with lighting or sprinkler systems. With limited pressure on the fan, it is also a fit-and-forget solution, with little to no maintenance requirements other than occasional cleaning of the blades in high pollution environments. The effectiveness of destratification fans has even seen the technology start to replace outdated and inefficient ducting. Cleverly positioned fans help to redistribute heat and air at a fraction of the cost. This is increasingly being used to great effect where obstacles are preventing the effective distribution of heat, such as warehouses with large racking systems, where heat needs to be channelled down aisles to warm operatives. With energy consumption a continuous battleground for building and facilities managers, and contractors tasked with reducing CO2 emissions, the effective use of destratification is an opportunity that cannot be missed. Taking into account low upfront costs, short payback periods and significant reductions in heating bills, it is perhaps time the whole industry reassessed the potential impact of destratification.


Thermal destratification, or the effective redistribution of heat and air through large spaces, isn’t new, and anyone who has visited a manufacturing site or warehouse will be aware of the large number of box fans used to recirculate air
