In commercial and industrial environments, air curtains play a vital role in maintaining indoor climate control, energy efficiency, and hygiene by creating an invisible barrier between indoor and outdoor air. However, the effectiveness of an air curtain depends not only on the quality of the unit but critically on its correct installation—particularly the mounting height.
Every air curtain model is designed with a specified maximum installation height. For example, if a unit is rated for a maximum of 2.5 meters, it must be installed no higher than that point. This specification ensures that the unit can deliver the necessary air velocity—2.5 m/s at floor level—to provide a proper seal across the doorway. Failure to meet this condition compromises the air curtain’s performance, leading to energy loss and potential infiltration of dust, fumes, and insects.
Moreover, real-world conditions seldom remain static. Situations such as strong wind gusts, negative indoor pressure, or high-traffic door usage demand a more robust air stream. In these scenarios, the air curtain must deliver a higher airflow rate to maintain the protective barrier.
This is where Berner air curtains distinguish themselves. Engineered to perform at higher installation heights and withstand greater wind loads, Berner units are designed with an operational buffer. That means even when faced with fluctuating pressures or environmental stressors, the system continues to deliver a reliable seal—without compromising efficiency or performance.
To further ensure reliability, all Berner air curtains are independently third-party tested and certified by AMCA (Air Movement and Control Association). This rigorous certification process gives specifiers, engineers, and building owners full transparency into the unit’s capabilities, including its tested maximum mounting height and performance parameters.
In an industry where assumptions can lead to energy waste and operational inefficiencies, precise installation in accordance with tested specifications is not just best practice—it is essential. With Berner, users can count on verified performance, optimal energy savings, and climate protection, even in demanding conditions.
