Engineered with high-torque copper-wound motors, dynamic rotor balancing, and continuous-duty thermal endurance to meet demanding commercial and industrial doorway sealing requirements across Luxembourg and the EU.
Luxembourg occupies a unique position in the European Union—functioning as a global banking headquarters, a major logistics crossroads (anchored by Luxembourg Airport’s CargoCenter and Eurohub South in Bettembourg), and a hub for high-precision biotechnology research in Belval. Situated in Western Europe's oceanic climate zone (Köppen Cfb), facilities in Luxembourg face sharp seasonal temperature swings, ranging from freezing sub-zero winters to humid summer peaks.
In this economic environment, commercial doorways and industrial loading bays represent major thermal leakage vectors. Unprotected open doors consume thousands of kilowatt-hours in wasted space heating and air conditioning annually. As Luxembourg accelerates its national decarbonization roadmap and strict compliance with the EU Ecodesign Directive (2009/125/EC) and local nZEB (Nearly Zero Energy Buildings) requirements, high-velocity air curtains are no longer optional luxuries—they are fundamental building energy infrastructure.
“A professionally engineered air curtain delivered to Luxembourg specs generates an invisible aerodynamic jet vector that seals up to 90% of outdoor climate transfer, lowering building HVAC energy consumption by up to 33%.”
Tailored engineering variants designed for the specific operational demands of Luxembourg's core commercial and industrial zones.
Deployed in Luxembourg City (Grand-Rue, Kirchberg Plateau) and Cloche d'Or. Sleek, whisper-quiet tangential air curtains preserve indoor thermal comfort, protect luxury retail spaces from street dust, and prevent conditioned air loss without physical barrier obstructions.
Specifically rated for high-frequency overhead dock doors at Findel CargoCenter and Bettembourg Eurohub South. Heavy-duty centrifugal air doors blast high-velocity air discharge (up to 25 m/s) to prevent wind-driven thermal loss during continuous truck loading.
Engineered for laboratory and pharmaceutical cleanrooms in Belval Innovation Campus. Incorporates HEPA/ULPA air filtration compatibility and stainless steel housing options to maintain ISO Class pressure cascades and prevent contaminant cross-entry.
The effectiveness of an air curtain hinges on maintaining a stable laminar velocity profile across the entire door width. If velocity ($V_0$) is insufficient, wind pressure ($P_{wind}$) will puncture the air jet. Conversely, excessive turbulent velocity creates unwanted mixing, pulling cold outside air directly into the occupied zone.
Our manufacturing process utilizes computer-modeled double-inlet centrifugal impellers and precision slotted discharge nozzles. By coupling high-torque copper-coil induction motors with aerodynamically optimized scroll housings, our units establish a uniform Coanda Effect air curtain stream with an optimum discharge angle (adjustable from 0° to 20° outward).

Since our inception in 1974, our manufacturing philosophy has centered on complete vertical integration. Unlike assembly-only exporters, our facility manages every core phase of production under one roof: from precision rotor punchings and automated copper wire winding to dynamic impeller balancing and routine electrical testing.
For engineering firms, contractors, and original equipment manufacturers (OEMs) in Luxembourg, we offer full custom-engineering capabilities. Whether you require specific CE voltage windings (230V 50Hz single-phase / 400V 50Hz three-phase), custom shaft length turnings, specialized mounting brackets, or anti-corrosive powder coatings for harsh environments, our engineering desk translates your CAD/BOM requirements into reliable series production.
