LINEAR BAR GRILLES
General Description
ØWhen performance and appearance is of prime importance, the CT linear
bar grille is the logical choice. It is equally suitable as a one piece individual
grille or as a continuous linear grille. Having a low noise level and uniform
airflow, CT is suitable for supply or return air and may be installed in a
ceiling, sidewall, floor or sill.
ØFront blades are available in two deflection angles 0° and 15°. The 15°
deflection blade is available in one way air pattern or two way air pattern.
ØThe Following Accessories are available with CT - Grills .
a. Opposed blade volume control damper in extruded aluminum black color BL.
b. Opposed blade volume control damper in steel construction black color AG-15.
c. A set of adjustable rear aerofoil blades to control the direction of air.
ØCT can be provided in convex or concave curved sections.
ØInternal or external mitered corner pieces for vertical or horizontal grille orientation.
ØAs standard the grille is supplied with Titus White Epoxy Powder Paint. Opposed blade dampers are supplied in
matt black finish.
ØAlternate finishes are available on special request, at extra cost.
Construction
ØManufactured from high quality aluminum extrusions, having different flange frame options. The end flanges are
mechanically crimped using a corrosion resistant angle section.
ØA set of individually adjustable rear mounted aerofoil vanes are available as an option.
ØBlades with streamlined shape with front widths of 3mm & 5mm are available.
ØMinimum nominal grille height is 50mm up to 300mm as standard. Other grille heights may be provided when
requested. Maximum single piece length is 1800mm, joining strips can be supplied for a continuous unbroken
appearance.
ØInstallation of the grille can be with either spring clips or duct mounting using concealed brackets / Screws.

Data Notes :
1. All Pressures are in Pascals
2. Throw are given for terminal velocities of 0.75 and 0.25 m/s.
3. Throw and Sound Values are based on a 1225 mm section. Multipliers for other lengths are shown below. -124. NC values are based on a room absorption of 10 dB, re 10 Watts. Corrections for lengths other than 1225 mm are shown below.
5. When the diffuser is used as a return, increase the NC value by 4. The negative static pressure is 0.8 times the listed total pressure shown.
6. This product has been tested per ASHRAE 70-91, with an ideal inlet plenum. If less than ideal inlets are used, sound levels may be higher.
7. Maximum available width is 61 cm except For continuous lengths it is recommended that maximum active lengths are no longer than 3000 mm.
8. Dash (-) in space denotes an NC value of less than 10.

ØCentral core is easily removable from the face of the diffuser.
ØExtremely flexible configuration with cores available for one- two- three-or four
way horizontal flow.
ØVolume control damper can be adjusted from the face of diffuser, by removing the
central core.
ØFollowing accessories are available with TDC diffusers
a. Opposed blade volume control damper in extruded Aluminium mill finish (type B) or black (type BL).
b. Opposed blade volume control damper in steel in black color (type AG15).
c. GI plenums with side or top entry for round duct connections with or without diffusion plate, with optional
lining for better acoustic and thermal performance.
ØTDC Diffusers are supplied in Titus White Epoxy Powder Paint as a standard.
ØAlternate finishes can be provided on request and at extra cost.
Construction
ØOuter frames and central core are manufactured from stamped aluminum sheet or high quality Aluminium
extrusion mechanically crimped available in following types
TDC 4 way core with stamped centre core & extruded aluminum frame
TDC-ASR 4 way core with anti smudge extruded aluminum frame
TDC-GT 4 way core with stamped outer frame for grid ceiling
