General Information
The primary reason for installing gas fired air curtains is to prevent the influx of cold outside air through a door opening into a heated area.
Typical applications include large dispatch bay doors in factories , shopping malls and warehouses, and internal doors between areas of different temperatures. Wider door openings can be accommodated by bolting two or more units together.
