Why Destratair

Why Destratair

Air Distribution - The Destratair product is unique in that it becomes the prime air mover not only pushing hot air back down into the occupied zone, but distributing the heated or cooled air evenly around the space.
Destratair fans are wall mounted at about 3m from the floor and throw air up across the roof creating an air movement back to low level which minimises draughts in the occupied zone unlike roof mounted units that blow downwards. This means we can achieve higher air movement rates and hence destratification levels of just 1 degree.

Installation costs – Using the Destratair product as the prime air mover can save a great deal on installation costs as there is no need to strategically position multiple heaters and distribution pipework or ductwork around the building to ensure coverage. This also means less pipework and equipment to maintain, and eliminates the need for ductwork cleaning.
Maintenance costs are further reduced in that the Destratair fans are easily reached without the use of high level access equipment.

Efficiency - In terms of energy conservation, No other destratification fan can match Destratair for efficiency and performance. The fans, that all have energy saving E.C motors, remain on during the heating period rather than cycling on and off at the dictate of a thermostat, meaning emitters reach set point and remain off for longer.
British Gas and ETSU carried out independent tests which clearly demonstrated that this method of air movement can produce fuel input savings of up to 20% compared to other methods of destratification such as overhead boxed fans or propeller fans which produced savings of up to 15%. The Destratair product has also been independently tested by specialist energy consultants and Sheffield University.
