High-rise buildings were one of the first to use revolving doors. They experienced immense pressure caused by air rushing through the building. This pressure was severe enough to cause problems, even with opening the doors. Revolving doors were designed to relieve stack effect pressure and to control indoor temperatures. However, there are certain areas of a building which require extra help to prevent temperature changes.
Air Curtains for Revolving Doors
In terms of energy savings, the use of a revolving door in your entrance is the most effective entrance solution. Air curtains have been developed specifically for revolving doors to maintain this effect at the entrance. This gives you the opportunity to decrease energy consumption even more by reducing heat loss in the winter and stabilising air-conditioned areas in the summer.
How Air Curtains Work
In most cases, air curtains are installed above entryways. They create a barrier of air over the revolving door. By essentially separating two environments, inside and outside, they maintain heating and keep out the cold (or vice versa). The air curtain houses a coil which cools or heats the jet of air. The temperature of the jets of air are adjusted to feel comfortable as you enter through the entrance of the revolving door.
Because air curtains create an invisible barrier between two areas, they help to keep out:
- The summer heat
- The winter cold
- Bad odours
- Exhaust gas
Air Curtains for Increased Sustainability
A revolving door including heater can put a stop to cold drafts. While air curtains are mostly associated with moderating temperatures, they’re also economic and offer a money saving solution for buildings.
- By fixing unwanted climate changes within the entrance area
- By separating indoor temperatures from outdoor climates
- By working through the winter and summer months
Installation requirements for Air Curtains
Air curtains work by installing the system horizontally or vertically. A horizontal installation is either integrated in the canopy or installed at the top of a revolving door. Another option is vertical installation which blows air in from the sides. When specifying for an air curtain there will be a space requirement. Air curtains can be installed in any form, from small door diameters to canopy implementations. Before specifying, you need to consider:
- the size of the air curtain
- power of the air curtain
- position of the air curtain (keep in mind door opening sizes)
- location of the revolving door
- type of building
- climate considerations
We understand revolving doors can come in a variety of shapes and sizes, which is why we offer a range of air curtain solutions. If you need help in deciding which air curtain is best to fit your entrance, contact your local entry expert for advice.
