10 things you should know about air curtains

These systems help maintain a comfortable indoor temperature year-round. In winter, they prevent cold air from entering, and in summer, they retain the conditioned air, resulting in significant energy savings.

Letting conditioned air escape through the doors is a waste of money. Thanks to the reduction in electricity and gas bills, the cost of purchasing and installing an air curtain is recouped quickly.

These systems generate an airflow that separates spaces with different temperatures, allowing the smooth passage of people, carts, or vehicles. They also prevent the entry of dust, insects, leaves, smoke, odours, and other wind borne particles.

Solutions are available for all types of openings: from small customer service windows to large industrial entrances up to 6 meters high.

To achieve maximum performance, it is best to include air curtains in the building plans and during the design phase. Although they can be installed later, doing so in an already completed structure sometimes requires modifications that could reduce the system's efficiency.

Not all doors are the same, so selecting the right equipment is vital. The air curtain must completely cover the width of the entrance and have enough power to reach the floor. In addition, factors such as traffic frequency, wind conditions, and the type of activity must be considered.

Depending on the installation, you can opt for models that work with electrical resistance or connected to a hot water circuit. There are also units without heat (neutral), which are mainly used in cold rooms to prevent the cold from escaping.

If the image of your premises is important, the market offers equipment with very elegant finishes that integrate into any decoration. They can also be installed embedded in the false ceiling; in this case, you just have to make sure that they have a free air inlet and that access for maintenance is simple.

Especially in fast-paced industrial or commercial environments, it's worth investing in robust equipment made from high-quality materials. This will guarantee a long lifespan for the device and fewer complications during installation.

The way these systems are regulated has evolved considerably. Methods range from a manual speed selector (ideal for doors that are always open) to self-activating door sensors or smart thermostats. Furthermore, it is increasingly common to integrate them into building management systems (BMS).

If you're looking for top quality, Frico's Thermozone range stands out thanks to the years of experience of this leading European manufacturer.
