More performance without compromise – The advantages of nozzle ducts in HVAC design

Nozzle ducts combine efficiency and comfort while solving multiple air distribution challenges in high-occupancy spaces.

Nozzle ducts have become established in ventilation design as a solution addressing several air distribution challenges simultaneously. Their high induction rate enables efficient mixing of supply air with room air, preventing draught even at high airflow rates. This gives designers greater freedom when dimensioning systems for schools, daycare centres, offices and restaurants that demand both substantial ventilation capacity and excellent indoor air quality. A key advantage lies in space optimisation. Unlike suspended ceilings that conceal ductwork, nozzle ducts can be integrated as visible architectural elements, allowing full room height to be used. Installation is streamlined when air distribution, balancing and sound attenuation integrate into a single solution, reducing component count and improving accuracy. Operationally, nozzle ducts offer smooth surfaces requiring minimal maintenance and preset adjustability that reduces commissioning work. Their flexible distribution patterns are especially valuable in adaptable spaces such as classrooms, where functions change without extensive renovation.
