In recent years, "air curtain" devices have become very popular in our country. They have a simple construction, are easy to install and operate. With their strong airflow, they create a temperature barrier at the entrance of a building, helping to maintain the indoor microclimate and comfort. Alongside various types of insulation and many different approaches to improving energy efficiency, the "air curtain" reduces heat or cooling losses.
They are extremely effective in shops, restaurants, and public buildings where there is a constant flow of people.
In addition to the well-known standard devices for air shielding of doors and windows, there are also air curtains for revolving doors – unique devices that must meet a number of requirements for successful and effective use. Like standard air curtains, those for revolving doors are designed to limit the entry of outside air through the doors of already heated or air-conditioned spaces.
Due to the need for high-tech equipment and the specific construction, this type of "air curtain for revolving doors" is manufactured and offered by only a few companies worldwide, including a Bulgarian manufacturing company.
During the finishing works of the MALL BULGARIA project, in competition with several European companies, "TANGRA" was chosen as the supplier of the air curtains for the revolving doors. The Bulgarian company fully met the client's requirements with its unique design, execution time, and price. In a short period, the products were manufactured and tested in "TANGRA's" aerodynamic laboratory, and after applying the powder-polymer coating in the color of the doors, they were delivered to the client.
When you visit the newly opened "Mall Bulgaria", you will feel the pleasant warmth from the air curtains for the revolving doors!
