What is an Air Curtain?
An air curtain creates an invisible air barrier over doorways, maintaining temperature and reducing heating and cooling costs by up to 80%.

Selection Criteria
Key factors for selecting an air curtain include installation height, door width, weather conditions, building design, and energy supply availability. The discharge angle of the air jet is crucial for efficiency.

Effectiveness and Benefits
Air curtains are effective in preventing energy loss by maintaining separate thermal zones. Rosenberg's EC air curtains reduce ventilation costs by up to 65% and offer energy savings, low motor temperature, and high performance.

EC vs. AC Technology
EC technology combines AC and DC voltages, offering efficiency and performance benefits over traditional AC motors.

Overview of EC Motors
EC motors operate on direct current but are supplied with alternating current, converting it within the motor for efficient performance.

Allgemeine Informationen / General Information Was ist ein Türluftschleier? Ein Türluftschleier ist ein Lüftungsgerät, das eine unsichtbare Luftbarriere über einen Eingang erzeugt um zwei verschiedene Umgebungen abzuschotten, ohne die Mobilität der Fußgänger und der Fahrzeuge einzuschränken. Der Betrieb eines Türluftschleiers stützt sich auf einen Hochgeschwindigkeitsluftstrom, der die ganze Öffnung abdeckt. Die Türluftschleier mit Heizung machen den Luftstrom komfortabler wenn Personen die Luftbarriere durchqueren, und helfen dabei die gewünschte Temperatur im Eingangsbereich zu erhalten. Deswegen...

Allgemeine Informationen / General Information Vergleich der EC- und AC-Technologie Die EC-Technologie (EC=elektronisch kommutiert) kombiniert den Wechselstrom mit dem Gleichstrom. Sie bringt das Beste beider Technologien zusammen: der Motor läuft mit Gleichstrom, aber er wird mit Wechselstrom versorgt. Die Umwandlung des Wechselstromes in Gleichstrom findet im EC-Motor statt. Das nicht drehende Teil des Motors (Stator) beinhaltet eine Platine, die die Stromumwandlung sowie die Steuerung des Motors ermöglicht. Die EC-Motoren haben keine Schlupfverluste, weswegen die Effizienz im Vergleich mit...
