Halton TRC Auditorium Diffusers
The Halton TRC auditorium diffuser is designed for installation within the step riser in auditoriums, theatres, concert halls, where good indoor climate conditions are required.
Supply air velocity should be very low to avoid draught in the near zone of the diffuser. The recommended supply air temperature is less than 3°C below the ambient temperature. The supply airflow rate is up to 18 l/s pr unit.
Where requirements for comfort are perceived to be less important, higher airflow rates can be used, resulting in increased velocities close to the diffusers. In such cases diffusers should be installed further away from continuously occupied areas.
Halton TRF Floor Diffusers

The Halton TRF auditorium diffuser is designed for installation in raised floors in auditoriums, theatres, concert halls, where good indoor climate conditions are required.
The recommended supply air temperature is less than 3°C below the ambient temperature. The supply airflow rate is up to 15 l/s per unit. Where requirements for comfort are perceived to be less important, higher airflow rates can be used, resulting in increased velocities close to the diffusers. In such cases diffusers should be installed further away from continuously occupied areas.
BCF floor diffusers are designed for installation in raised floor systems like auditoriums, conference rooms, theatres, where a high level of comfort and conveyance is required. Air is supplied into the space through the front panel at a low velocity, mixing with room air above the diffuser.
