Linear Grilles 02

COSMOS Linear Grilles and Registers covers a wide range for supply and return air distribution of HVAC systems and are suitable for ceiling, floor, sill and sidewall applications. They are selected for their pleasing continuous, line, architectural appearance and are designed for ventilation outlets and many other applications.

COSMOS Linear grille series CL and CLE comes with standard widths ranges from 2″ to 10″. Linear Grilles & Registers are multi parallel fixed bar type in continuous modular section up to 2 meters long to form linear type grilles.

Cosmos grilles are designed for cooling applications, supply and return. The grilles are manufactured with precision mitered corners to maximize quality. They are available in one way airflow pattern for 0, 15, 30 and 45 degree bar deflection and in one or two way air flow pattern for 15, 30 and 45 degree bar deflection. For quiet airflow, bars are equally spaced at 12.5mm distance. Mullion bars across the blades provide additional strength. Series CLE – CU is linear curved grille. The curved linear grille offers a wide range of blade formats to meet both architectural and system requirements and is ideally suited to side wall, bulk head or sill applications. The grilles can be fabricated in a curves in a variety of radii to suit the specifier. Grilles can be supplied in modular units or, for continuous applications, in single sections up to 2m.

When installed in the ceiling linear grille provides vertical downward air pattern which is effective in projection cooling or heating the building parameter from ceiling height above 12 to 15 feet. Air volumes for down flow applications should be restricted to ensure against excessive drafts at the end of the throw. Core deflections of 0, 15 and 30 degree direct the air path angularly downward as required by the designer.

When installed in the sidewall near the ceiling, linear grille provides horizontal pattern above the occupied zone. Core deflections of 15 and 30 degree direct the air path upward to overcome the drop effect resulting from cool supply air. Use of deflected cores also improves sight tightness of the grille face.

When installed in sill of a window or enclosure or floor linear grilles provides a vertical up pattern which can effectively overcome radiant effect of glass surfaces or cold down draft during winter.

Opposed blade volume control dampers can be provided with all linear grilles effectively turning them in to registers suitable for volume control.
