With air curtains, a pleasant and stable interior temperature is a matter of course. The curtains reliably prevent the escape of warm air in winter and air-conditioned air in summer while also providing heating. Our air curtains have several exceptional technologies: The STRAW SYSTEM, which we were the first in the world to use, ensures a constant airflow and thus better shield effect properties. DUAL AIRSTREAM technology, combining two air streams, reduces heat demand and thus reduces operating costs. And thanks to the FACE 2in1, our suction grill technology, there is no need to disassemble the curtain for service, making cleaning and maintenance much easier.
