Displacement flow diffusers discharge the air from air conditioning systems with a low velocity and near the floor. The low-turbulence airflow creates a pool of fresh air that covers the entire floor area. The convection from people and other heat sources causes the fresh air from the pool to rise and create comfortable conditions in the occupied zone.

This draught-free and economical type of ventilation is also suitable for large internal spaces, such as auditoriums or shop floors, with several regularly arranged units.

Displacement ventilation is characterised by low airflow velocities and low turbulence. The air quality in the occupied zone is very high.

Displacement ventilation with air discharge near the floor is suitable only for cooling. The maximum supply air to room air temperature difference is –6 K.

Application

Type CTU displacement flow diffusers are used as supply air units for industrial and comfort zones

Attractive design element for building owners and architects with demanding aesthetic requirements

Floor-standing installation on walls or in corners

Low-velocity airflow, causing only low levels of induction and resulting in low-turbulence displacement ventilation.

Excellent air quality in the occupied zone

Draught-free and economical ventilation and air conditioning also of larger internal spaces such as shop floors or auditoriums, with several displacement flow diffusers in a regular arrangement

For variable and constant volume flows
