requirements, they can even be configured to re-circulate warmed air within the building and add to the energy efficiency and economy of the unit.
REDUCE HEAT LOSS
Energy efficient air curtains, such as those supplied by Airbloc, can be positioned directly over or down the side of a doorway. When doors are opened in heated build- ings, colder external air flows in through the bottom part of the opening, while internal air flows out through the upper part. In air conditioned buildings, the opposite applies. Over door air curtains deliver a uniform flow of air across the full door width that sepa- rates the interior and exterior atmospheres. As well as their energy-saving capacity, the air curtains also have ‘hidden’ benefits. Over door air curtains induce warm air down from high level that would otherwise be lost through the roof, thus helping to de-stratify the building and eliminate cold spots. Furthermore, when combined with an energy-saving control unit such as the SmartElec2 from Airbloc, both power con- sumption and energy costs can be reduced
by up to 50%. The attractive unit offers a number of control options to suit all applica- tions including thermostats linked to door closed sensors that turn units down or off to increase energy saving. Outside tempera- ture sensors can also turn the elements off in warmer times, whilst timers will ensure the units only operate when required. In addition, air curtains are not subject to the same wear and tear as roller-shutter doors, so mechanical failures and dam- age can also become a thing of the past. So, for energy savings or not having to replace worn-out doors, air curtains can help contain overhead costs while preserving comfort for employees and maintaining ideal conditions for stock. Air curtains are so effective that doorways can remain open all day with very little effect on the heating system’s energy consump- tion or the comfort of employees inside the building. With the simple installation of air curtains, businesses can stop their profits from sneaking out the back door. n
