 Displacement Diffuser  A to Z Products
 Introduction
 
Displacement ventilation systems, as the name implies, rely on a displacement process of the supply air into the occupied zone. Typically the supply air is introduced at low level and at a low velocity to displace the room air and provide layers of cool fresh air in the occupied zone while the extract removes stale air at high level.

The displacement diffusers are ideally suited for use in areas with high heat loads requires. By using the effects of convection to lift the supply air from heat sources, whilst at the same time removing any pollutants, the air is then extracted at high level, thus creating an even temperature, draught free, clean environment.

COSMOS displacement diffusers are designed to produce a low turbulence horizontal air supply in 180 degree pattern. Typically installed against a wall or pillar that discharges air evenly across its perforated face. The cool air then drops to the floor and gently floats into the occupied zone. This appealing diffuser meshes seamlessly into any décor, providing a curved detail to the space.

COSMOS make CDD-SC is a semi-circular displacement diffuser with a 180 degree air discharge pattern. It is great for wall or surface mount applications and can be easily integrated into semicircular building columns.

The superior air quality and low noise levels realized with the CDD-SC make it suitable for office spaces, hotels, convention centers, schools or any application where air quality demands are high. The CDD-SC can supply a large volume of air at low velocity into the occupied zone.
 
  Construction
 
Displacement diffuser CDD-SC built in standard construction, sizes and surface finishes. The casing is made from galvanized sheet steel with circular inlet spigot. The outer active casing is made from perforated sheet steel plate with 3 mm diameter holes.

An inner casing with integrated elements guarantees equal air distribution over the whole surface. The surface finish is powder coated RAL 9016.
