A solution for warehouse businesses to prevent energy escaping out of the back door and denting their profits is Reznor energy efficient air curtains.
These air curtains cut energy loss by more than 80%, delivering a uniform flow of air to separate the interior and exterior atmospheres, maintain the internal climate, offer significant cost savings and deliver vastly improved worker comfort.
Providing a comfortable and safe working environment is paramount for every business owner – however, the opening and closing of external doorways cannot be prevented in warehouses, making warm air escape and cold air enter, creating a huge difference to fuel costs.
Along with the inevitable increase in energy bills, opening and closing external doors will also affect internal temperatures and reduce comfort levels for employees – in particular those working near the doorway.
And for warehouses storing perishable items, temperature sensitive stocks can also be compromised.
Comparative temperature readings typically show a drop between 4°C and 10°C every time a warehouse door is opened, but a correctly sized air curtain will lower the difference to usually just 1°C.
With an over door air curtain, energy lost through open doors which was previously seen as unavoidable, can actually be lowered to as much as 80%.
The effectiveness of air curtains in separating internal and external environments means doorways can remain open all day with very little effect on the heating system’s energy consumption, with relatively little impact on internal comfort conditions.
Energy efficient air curtains, such as those supplied by Reznor, can be placed directly over or down the side of a doorway. When doors are opened in heated buildings, 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 separates the interior and exterior atmospheres.
As well as their energy saving capacity, 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.
Among the air curtains’ new developments is a fresh design that promotes a laminar airflow and features deep profile aerofoil section air straightening veins. These improve the efficiency of climate separation between the indoor and outdoor environment, compared to previous models.
In addition, air curtains are not subject to the same wear and tear as roller-shutter doors so mechanical failures and damage can also become a thing of the past.
Air curtains can ensure energy savings and contain overhead costs, whilst preserving comfort for employees and maintaining ideal conditions for stock, without the need to turn down the heating or turn off the air conditioning system.
The air curtains feature even easier installation, which reduces site time, lowering costs in turn.
AB air curtains can be supplied as ambient models or heated models using gas, hot water or electric.
