TURBULENCE DIFFUSERS

Product catalog summary

Turbulence Diffusers Overview
Turbulence diffusers are designed for air conditioning systems to create turbulence and supply air to rooms. This process helps in reducing airflow velocity and temperature differences between supply and room air, allowing for large volume flow rates and effective room ventilation with minimal turbulence in occupied zones.

Types and Specifications

TWD226R: Features fixed, circularly arranged blades with a circular front plate.
TWD226K: Features fixed, circularly arranged blades with a square front plate.

Both types are made from sheet metal and have a horizontal radial air discharge. They can handle a temperature difference ranging from -12 to +10 K.

Finishing and Installation
The diffusers are powder-coated in RAL9010 as standard, with other colors available upon request. Installation options include bridge, screw, or no fixing, and accessories like a plenum box are available.

Plenum Box Details
The plenum box includes components such as a diffuser face, damper blade for volume flow rate balancing, pressure tap, and cords for damper blade operation. It is available with either a square or circular front plate.

Installation Details
Installation can be done in grid, continuous, or T-bar ceilings. The process involves fixing the plenum box to the ceiling and attaching the diffuser face after ceiling completion.

Order Codes
Order codes specify the type, frame size, mounting method, and coating options. For example, TWD226R with screw mounting and RAL9010 coating is coded as SWD-124 SQF RAL9010 SM F 595x595.

TURBULENCE DIFFUSERS DESCRIPTION: Ceiling turbulence diffusers in air conditioning systems create a turbulence to supply air to rooms. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. Ceiling turbulence diffusers allow for large volume flow rates. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone.
