Entrances are one of the main points of exchange between the indoor and outdoor environments of buildings. Frequent door opening causes heating and cooling losses and allows outside air, dust, insects and other pollutants to enter, affecting both occupant comfort and the energy efficiency of the installation.
In this context, solutions that help minimise these effects are essential to maintain more stable indoor conditions without interfering with the regular flow of people or goods.
To meet this need, SODECA offers air curtain solutions for commercial and industrial applications.
SODECA’s air curtains create an invisible barrier between the indoor and outdoor environments of the building, reducing heating and cooling losses, limiting the ingress of external elements and helping to maintain more stable indoor conditions.
Available in horizontal, vertical and recessed configurations, SODECA solutions for entrances adapt to the characteristics of each installation to provide the right solution for every type of entrance.
Improved thermal comfort and protection against external elements
SODECA’s air curtains help improve the energy efficiency of buildings by reducing heating and cooling losses through open entrances. They also minimise draughts and help maintain more comfortable indoor conditions.
Their continuous airflow creates a protection barrier that limits the ingress of airborne dust, insects and other pollutants, helping to protect indoor spaces and maintain better indoor environmental conditions.
In addition, their optimised design generates long-range air flows while maintaining low power consumption.

Multiple applications and the right solution for every entrance
Thanks to the range of models available, SODECA’s air curtains are suitable for applications including retail and commercial premises, service buildings, logistics facilities and industry, meeting the specific requirements of each project.
Each type of entrance has specific requirements depending on its height, dimensions, use and operating conditions. For this reason, SODECA offers different air curtain solutions that make it easier to select the right solution for each project.
In addition to the type of installation, it is important to select the air curtain operating mode according to the requirements of each project. SODECA offers different versions, allowing the solution to be adapted to the characteristics of the building and its existing heating system:
- Environmental: Recirculates indoor air without adding heat, making it a suitable option for creating separate zones and reducing air exchange between indoor and outdoor environments.
- Electrical: Incorporates electric heating elements to provide heat, offering a quick and easy solution when additional heating is required.
- Hot Water: Equipped with a hot water coil for integration into hydronic heating systems, making it particularly suitable for buildings with centralised heating.

Depending on the requirements of each application, SODECA offers different air curtain solutions for different types of entrances.
The ECONOMIC model is specially designed for small retail premises such as shops, cafés and offices.
For retail and commercial applications, the COMERCIAL model is the most versatile solution for entrances in supermarkets, hotels, shopping centres and other similar premises.
When discreet integration is required, the EMPOTRABLE model provides a recessed installation in false ceilings, making it particularly suitable for offices, hotels, corporate buildings and retail premises.
Finally, the INDUSTRIAL/EC model has been developed for large entrances in industrial and logistics applications. Its modular design, available in horizontal or vertical configurations and equipped with EC Technology motors, allows it to adapt to large dimensions and installation heights of up to 8 metres.
With these air curtain solutions for commercial and industrial applications, SODECA provides designers, engineering companies and installers with solutions adapted to the specific requirements of each application.
SODECA offers designers, installers and distributors a comprehensive range of air curtains developed to reduce energy losses and improve thermal comfort in indoor spaces, with solutions adapted to the requirements of each type of building.
In addition, SODECA’s Sales Department provides personalised advice to help select the most suitable solution according to the characteristics of each entrance, installation conditions and the specific requirements of each project.
