General information

Application

Type TSD slot diffusers are used as supply air or extract air devices in comfort zones
Unobtrusive diffuser due to its sleek flat face design
Installation into suspended ceilings or plasterboard margin
For room heights up to 4 m (lower edge of suspended ceiling)
For suspended ceilings; suitable for restricted ceiling voids due to the low overall height of the plenum box
Suitable for continuous linear arrangement
Adjustable air control elements allow for horizontal or vertical air discharge
Mixed flow system with adjustable air discharge, can be adapted to the building structure
High induction results in a rapid reduction of the temperature difference and airflow velocity (supply air variant)
For variable and constant volume flows
For supply air to room air temperature differences from –10 to +10 K

Special features

Uniform air pattern increases comfort and reduces noise level
Horizontal, or vertical air discharge by means of manually adjustable air control blades
Comfortable indoor climate due to high induction and rapid reduction of temperature differences and airflow velocities
High-quality look thanks to extruded aluminium sections with RAL CLASSIC polyester powder coating
Diffuser face has been optimised for maximum volume flow rate at low sound power levels and low pressure
Suitable for continuous linear arrangement

Nominal sizes

Single diffuser

L_N : 300mm up to 1800mm

Linear diffuser

L_N : > 1801mm & ≤ 3600mm linear diffusers supplied as two equal length end sections

L_N : > 3600mm linear diffusers supplied as n x 1800mm middle section(s) and two equal length end sections.

For a continuous linear arrangement the diffuser should be ordered with total run nominal length. Diffuser will be supplied in sections (2 x equal length end sections or n x 1800mm middle sections and 2 x equal length end sections depending on nominal length) with alignment pins for joining on site by others. End plates or end angles have to be specified and will be factory fitted to diffuser end sections.

Intermediate sizes in 1mm increments available on request.

Slot diffusers direct the air from air conditioning systems into the room, either horizontally or vertically. The resulting airflow induces high levels of room air, thereby rapidly reducing the airflow velocity and the temperature difference between supply air and room air. The result is a mixed flow ventilation in comfort zones, with good overall room ventilation, creating only very little turbulence in the occupied zone. Type TSD slot diffusers are factory fitted with manually adjustable air control blades. The diffuser can be supplied with Continuous air control blades for one-way horizontal airflow control or vertical airflow to provide additional control to meet different local requirements. Air discharge is one-way (1 slot) or two-way (2 or more slots). Other patterns: heating mode with vertical air discharge. The supply air to room air temperature difference may range from –10 to +10 K. A damper blade (optional) simplifies volume flow rate balancing for commissioning. To give rooms an aesthetic, uniform look, Type TSD diffusers may also be used for extract air. Type TSD-AKV plenum boxes and return air baffles are available to suit the local requirements of the installation with optional 12mm internal lining.

Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures. Exact values for all parameters can be determined with our Easy Product Finder design programme.

Specification text

Slot diffusers of Type TSD, with 15 or 20mm nominal slot width, individually manually adjustable air control blades and 1, 2, 3 or 4 slot configuration. Factory fitted with manually adjustable air control blades. The diffuser can be supplied with continuous air control blades for one-way/two-way horizontal airflow or vertical airflow or blades made up of 300mm sections for alternating horizontal airflow to provide additional control to meet different local requirements. The slot diffusers are intended to be installed in suspended ceilings and are suitable for supply air and extract air. Ready-to-install component which consists of a diffuser face with a choice of black or white air control blades. TSD-AKV plenum boxes have 1 or 2 spigots with side entry or top entry connection. The plenum boxes are fitted with 4 suspension lugs with optional 12mm internal lining. Side entry spigots can be fitted with optional spigot mounted damper for volume flow rate balancing. Spigots are suitable for circular ducts according to EN 1506 or EN 13180. The sound power level of air regenerated noise is measured according to EN ISO 5135.

Product Details, Dimensions

One-way horizontal air discharge to the left

Installation details [S11]

When specified, TSD diffusers are supplied with 'S11' fixings to enable diffuser installation to TROX plenum box type TSD-AKV. S11 fixings are supplied loose for installation to the diffuser by the installer to correspond to position of installed plenum box.

Quantity of S11 fixings supplied with each TSD diffuser is based on slot quantity;

TSD**-1...2: 2x S11 fixings per diffuser

TSD**3...4: 4x S11 fixings per diffuser

Installation details [GP]

When specified, TSD diffusers are supplied with 'GP' fixings to enable diffuser installation within ceiling systems without TROX plenum box type TSD-AKV. GP fixings are supplied loose for installation to the diffuser by the installer to each TSD diffuser section.

2x GP fixings are supplied with each TSD diffuser section when specified. NB: 1x GP fixing is also supplied with each diffuser section when S11 fixings are specified to cover diffuser nominal lengths > plenum box length (border style FL, NF only).

GP fixings are designed to clamp the diffuser against the project ceiling system (ceiling depth between 1... 40mm). A minimum 25mm clearance should be provided to either side of the opening to facilitate installation with GP fixings.

Installation details [SB]

When specified, TSD diffusers are supplied with 'SB' fixings to enable diffuser installation within ceiling systems without TROX plenum box type TSD-AKV. SB fixings are supplied loose for installation to the diffuser by the installer to each TSD diffuser section.

4x SB fixings are supplied with each TSD diffuser section when specified. NB: 2x SB fixings are also supplied with each diffuser section when S11 fixings are specified to cover diffuser nominal lengths > plenum box length (border style PL only).

SB fixings are designed to facilitate support to the building structure via Ø6mm threaded rod or wire supports (by others). Fixings are accessed via the rear of the diffuser only so suitable access to the ceiling void shall be required.

SB fixings can be bent to vertical position if required to suit installation method.

Installation details Linear Diffusers

When linear diffusers are requested (LN > 1801mm) diffuser will be supplied in sections;

LN >1801mm & ≤3600mm

End: 2 × equal length sections

LN >3601mm

Middle: n x 1800mm sections

End: 2 × equal length sections

Alignment pins (2 per middle or end section) are supplied loose for installation between linear sections by the installer.
