Hot air curtains are fans that create a wind barrier between the outside and inside of a room. When well designed and properly installed, these windy barriers can cut down on heating costs significantly when compared with an unblocked entryway. In any structure- a house, a warehouse, or an office- a very large amount of the heating or cooling costs involve replacing the air that leaks out. In some temperature regulated buildings, the entrance, and exit are constantly being used, essentially creating a large permanent leak of hot or cold air. Hot air curtains shoot a stream of air down along the opening, essentially isolating inside air from outside air. Hot air curtains can be good for saving money on utilities, and have the added bonus that they keep insects out.
As an application for hot air curtains, warehouses seem ideal. Many warehouses are kept at a constant temperature, either due to temperature requirements for items held within the warehouse or in the interest to maintain a productive climate for workers. The heating and cooling costs on these warehouses are large considerations for the owners. Warehouses are especially well suited, as some of their entrances and exits do not move people, just boxes or items that can be blown with high velocity air. Savings can be greater for warehouses that act as cold storage. See the picture below for a large and powerful air curtain deployed at a cold storage warehouse.
Large office buildings are also a suitable for hot air curtains. If the traffic through sliding doors is significant enough throughout the day, sliding doors might spend significant time open, making a hot air curtain a tempting option to save on heating costs. Cruise ships sometimes also deploy air curtains, which allow for its passengers easy movement around the boat while maintaining temperature and humidity. Retail locations sometimes use air curtains. In certain instances, a store chooses an air curtain to attract customers, as having an open entrance is more enticing than a door. Air curtains are also deployed between two indoor areas, a specific example being a colder area of a supermarket.
If you own a small shop, you need to have a hot air curtain. Installing a hot air curtain inside an external door creates a barrier of air that keeps cold air out and warm air in, even with the door invitingly open. Hot air curtains also act as an additional heat source and in small shops can act as the only heat source required.
