The engineering behind the space

Engineered around the displacement principle.

Gerhman displacement diffusers introduce air cooler than the room at low level and with limited momentum. The air spreads near the floor before joining thermal plumes generated by people and equipment, carrying heat towards high-level extraction.

The perforated discharge surface forms the interface between the ventilation system and the occupied space. Diffuser geometry, airflow and positioning are selected together to support the intended air path and local thermal comfort.
