In 1956, Erling Berner brought European technology to the United States and formed Berner Industries, the foundation of today’s Berner International Corporation, which is the first manufacturer of air curtains (also known as air doors) in the U.S.A. In the late 1970s, Berner took the lead in approaching the other air curtain (air door) manufacturers to work with A.M.C.A. (Air Movement Control Association) to successfully develop a certified method of rating air curtain performance. Product performance is critical, and at Berner, we believe our customers deserve the best assurance that our products perform as stated. In business for over 50 years, Berner has a reputation for customer service, innovation, aesthetics, quality and performance, and is proud to be a leader in systems that save energy and create healthy, comfortable environments.
