An air door or curtain is a tool used to separate two different temperature environments to mix with each other. For example in a general store, when customers come in or go out, they open the door every time and a significant amount of cold or hot air depending on the season is lost. It affects the overall consumption of electricity used for the cooling or heating the interior of a room or building. Similarly, in a bakery, a refrigerated room door may be opened and closed frequently to pick up the items. So, this repetitive opening and closing will ultimately result in loos of energy and efficiency of the air conditioners.
The need of air curtain doors becomes more essential if in case door remain open all the time. This situation could be noticed in drive through windows, restaurant doors, or shipping receiving doors, aircraft hangers, food processing plants and store entrances. Another example could be a production plant where fumes of fuel, oils, greases and other chemicals spread over all of the building. In all these cases, air curtain doors provide a best possible solution to make the inside environment more clean, hygienic and comfortable. It will ultimately reflect in the overall production quality of the unit.
How Air Doors Work - Some Basic Know How of The Product
A typical air door basically produces a strong jet of air to flow across a door opening, when mounted over the top of a door. It blows the high velocity air like a jet from top to bottom of the door opening. The high velocity air produced prevent the outside air to enter as well the inside conditioning to get lost. Further, these doors are capable of producing heat where needed. Heated and unheated air doors are two major categories in air doors or curtains. Unheated air doors are often used in cold storage and refrigerated rooms. Food service air doors are typically designed for food processing plants. Another classification is the industrial air curtains and commercial air curtains.
Air curtain doors are manufactured with different heating options, colors and mounting preferences, and a selection of accessories to alter the air door curtain for any application set. Heating options include electric, steam, or hot water coils and gas fired duct furnaces. Air doors are generally selected by the height of the door and a typical industrial air curtain can handle outside air of 30 miles per hour speed. It may be the only limitation faced in windy areas. Air curtains not only preserve the inside sanitation levels of the location, but it also cut the operational energy costs consumed on air conditioning. So, its wise to compare the difference and start cutting down the energy bills.
