FLOWTECH provides a wide range of Ceiling Diffusers to suit the various requirements of ceiling air distribution.
Supply air ceiling diffusers (SCD) and return air ceiling diffusers (RCD) can be Square or Rectangle in shape with One, Two, Three or Four Way Patterns. The different diffuser patterns are used to control the supply air direction. Typical examples of such application are supply diffusers near glass areas, in corridors and in corners.
FLOWTECH SCD is supplied with Opposed Blades Damper (OBD) to facilitate the precise air volume control. (Note: OBD is used for fine tuning the air volume flw rate and should not be used to replace the branch Volume Control Damper). RCD is supplied without OBD and usually used for return air applications. In certain applications, SCD must be used as return air diffuser; that is, where return air volume requires precise control, such as room pressurization applications. This is frequently required for Clean Room Engineering application such as Hospitals, Pharmaceutical Plants, Biotech Laboratories, Computer Rooms and Silicon Industry.
SCD and RCD are commonly used for Heating, Cooling and Isothermal Ventilation applications. However, such applications are limited to 4 meters ceiling height. For Ceiling Heights above 4.0 Meters, refer to specially terminal devices such as Jet Nozzle Diffusers and Drop Ceiling Diffusers.
SCD and RCD are tested by Intertek to ASHRAE 70 - 1991 standard method of testing for rating performance of air outlets and inlets.
Perforated ceiling diffuser (PCD) is of the same construction as SCD but with a removable perforated face of GI sheet powder coated, or aluminium sheet as optional.
