Displacement Flow Diffusers

Product catalog summary
Overview: The document outlines the technical specifications and operational principles of TROX HESCO displacement flow diffusers, which are essential for effective air supply in displacement flow ventilation systems. These diffusers are designed to enhance ventilation efficiency and thermal comfort in workspaces and occupied areas.
Construction: The diffusers are made from galvanized sheet steel with a perforated face plate featuring 3 mm holes. They are painted in white (RAL 9010), with other color options available upon request. The units are maintenance-free due to the absence of filter material and include special polypropylene nozzles.
Principle of Operation: The diffusers use special nozzles with integral air deflector scoops to control air discharge velocities and sound power levels. Charts are provided for quick selection of these parameters.
Applications: These diffusers are ideal for environments prioritizing low pollutant contamination and optimal thermal comfort. They can be adapted to various interior designs due to their diverse shapes.
Technical Data: Detailed technical data is provided for quick selection, including dimensions, flow rates, discharge velocities, and sound power levels. Custom dimensions can be requested.
Installation: The diffusers are delivered ready for installation, with instructions included. Magnetic fixing methods for the flat face plate are available upon request.
Specifications and Order Details: Specification texts and order details are provided for different diffuser types, including wall-mounted and free-standing units, with various size and configuration options.
Specifications:
  • Spigot Options: EO (Rectangular spigot top), EU (Rectangular spigot bottom), O (Without plenum box).
  • Color and Finish: Standard color is RAL 9010 with gloss options of 25%, 50%, 60% depending on market area. Custom RAL and NCS colors are available.
  • Dimensions: B (Width) × H (Height) × T (Depth) for general dimensions; D x H for WR; B x H for WV, WQT.
  • Base Options: Standard without base, optional base heights of 50, 60, 70, 100, 150, 200 mm.
  • Material Options: A2 for stainless steel smoothed finish.
Procedures:
  • Flow Rate Measurement: Equipment is available for diameters Ø125 to Ø800.
Order Details:
  • Includes specifications for room height (hR) and duct cover extension (Kx) based on room height.

Displacement Flow Diffusers-22

22 General technical information for the selection of TROX HESCO displacement flow diffusers Displacement flow is different from mixed flow not only in that the discharge point is no longer in or near the ceiling area but also in that the air movement is driven by the thermal convection generated by users of the space, machines, computers etc. Because the outlets for displacement flow are normally in the occupied zone, the discharge velocities are very low compared to mixed flow. 0,1 to 0,2 m/s in comfort conditioning and up to a maximum of 0,5 m/s in industrial applications or situations where...
