About SAW Airwalls
SAW Stäudtner Air Walls GmbH (SAW Airwalls) is a technology company based in Mönchengladbach that develops, plans and installs industrial air walls. The systems use fans and a patented nozzle to generate a thin, fast air jet that separates air environments in buildings and refrigerated vehicles without blocking passageways. Applications include thermal insulation of gates, cold insulation, odour and smoke containment, and insect protection. The standard product lines Compact, Grand and Move are continuously further developed using CFD simulation, full-scale experiments and digital twins; SAW offers full service from consulting and planning through logistics and installation to maintenance, UVV inspections and retrofit. Customers come from retail, logistics, waste management and recycling, manufacturing, the food industry and public buildings. With more than 2,000 installations in 12 countries since 1996, the company primarily implements its customers' energy strategies and occupational safety objectives.

Technology and Processes
Air Wall
Precise barrier of accelerated air that separates different air environments without obstructing access and saves energy.
CFD simulation and digital twins
Numerical flow simulation and full-scale experiments to optimize systems by up to 40%.
Heat pump
Used in the Airwall Compact since 2010 for active thermal separation.
