Description

The DRT/DRTI is a ceiling-mounted supply air diffuser featuring rotatable nozzles designed for comfort ventilation in various settings, including offices, schools, retail stores, restaurants, and hospitals. The simple rotation of the aerodynamically shaped
nozzles allows for flexible airflow patterns, ranging from horizontal, swirl, uni- or bidirectional, to vertical modes. Unless
otherwise specified, the diffuser is delivered with nozzles positioned in a rotating pattern. The diffuser operates at low noise levels, ensuring a draught-free and comfortable indoor environment. The difference between the DRT and DRTI is that the outer dimensions of the DRT type vary with connection sizes, while the DRTI maintains a consistent external dimension of 595x595 mm across all sizes.

Applications

The DRT/DRTI diffuser is ideal for ventilating comfort rooms where draught-free operation at low noise levels is important, such as offices, schools, retail stores, hospitals, and restaurants. The recommended maximum temperature difference (Δt) between the room and the supplied air is -12°C.

Standard sizes

• DRT: 125, 160, 200 (dimensions vary with connection sizes)
• DRTI: 125, 160, 200, 250, 315, 400 (consistent external dimension of 595x595 mm across all sizes)

Airflow range

50 - 600 m³/h (14-160 l/s)
The performance data of the DRT and DRTI are identical, differing only in their dimensions.

Materials and finish

• DRT: The front panel is made of galvanized steel. The frame is made of aluminum. The front diffuser plate and frame is powder coated in RAL 9003 white color. The nozzles are made of polypropylene.
• DRTI: The front panel and frame (up to size 200) are made of galvanized steel. For sizes larger than 200, the frame is made of aluminum. Both the front diffuser plate and frame are powder-coated in RAL 9003 white color.

Optional accessories

• TK: Our flagship commissioning box, with a low build height featuring environment friendly sound absorbent insulation, a supply air distribution plate and a removable damper module for commissioning and measuring of the airflow. The low height is possible by the internal socket design of the diffuser connection, minimising the total height of the diffuser and box, when assembled together.
