Selection CriteriaPerformance data is based on grilles situatedwithin 0.6m of ceiling with supply air at an 11°Ccooling differential. Throw is the horizontaldistance from the grille face to the point at whichthe velocity of the airstream has retarded to0.4 m/s.For grilles situated 0.6m or more below ceilinglevel reduce throw by 1/3. NC is sound pressurelevel/Noise Criteria Curve based on a roomabsorption of 8 dB for sound power (Lw) ref10-12 W.

IntroductionThe Waterloo 1RV & 2RV are designed to fit directly ontothe side of an exposed circular duct without the need for astub duct or transition piece. The flange is suppliedcomplete with a foam sealing gasket on all 4 sides. Theseunits can be provided with either a single row of verticalblades, or a set of vertical blades at the front and a set ofhorizontal blades at the rear. There are a range of sizes foreach grille to suit ducts from Ø125 - Ø1500. Each grille canbe supplied with an aluminium opposed blade damper ifrequired.

IntroductionThe Waterloo reversible core grilles have been designedfor commercial projects requiring aesthetically attractivegrilles but with a superior performance. The speciallydesigned, close pitch vanes, produce high levels ofinduction and mixing with ambient air resulting in moreeven air diffusion in the occupied zone. The core isremovable and may be rotated or reversed to provideeither 5° or 15° deflection upwards or downwards; inaddition the core can easily be cleaned before replacingin the frame. Alternatively any of the Exhaust grille orairline linear grilles cores may be specified.

T x 0.9 x 0.9 x 1.0 x 1.0 x 1.1 x 1.1
Notes:For grilles with OBSS opposed blade damper(open), multiply the pressure loss by 1.5 and add3dB to the NC level.
Where AL2 grilles are used multiply Ps x 3.0 andadd 6dB to NC level.
Grille selections for sidewall and cill applicationsshould be based on a minimum discharge velocityof 2m/s.
For sidewall grilles that are to be mounted morethan 0.2m from the ceiling, it is preferable to usea 15° blade format.
For sidewall grilles mounted 0.5m or more belowceiling level the throw is reduced by 1/3.

Acoustic transfer grillesDSRX
IntroductionThe Waterloo series DSRX have been developed foruse in partitions and doors where a reduction in noisetransfer or “cross-talk” from one space to another isrequired, as well as ventilation air transfer.
The DSRX are manufactured from high qualityaluminium extrusions with channel section coresforming a labyrinth airway lined internally withacoustic damping media. The cores are retainedwithin a flanged frame which is fitted with a sealinggasket. Units are supplied with fixed border andmatching adjustable rear border frame.
DSRX units will only provide acoustic isolationimprovements over that of a clear aperture. DSRX unitsmay be used in series to increase transmission loss.

IntroductionThe Waterloo WPT grille is a sidewall grille made withan aluminium frame and a steel perforated plate. Theperforations on the plate are angled to supply air in afixed direction.
The standard “plenum box” wall mounting that comeswith a supply grille, is angled in order that the air streamis trained vertically down the wall and along the floor.This floods the floor with fresh cool air. As the air heatsup it rises and is extracted from the top of the room (Thissystem is sometimes refered to as “displacementventilation”).
When used for extract the grille should be mounted highin the room and flush with the wall.
This grille provides a good air distribution with lowvelocities and low sound levels. With minimal air mixing.
Product DescriptionWPT-T Supply Grill (including plenum)
WPT-R Extract Grill (including AF-subframe)
Features• High levels of comfort due to low velocities
• No plenum assembly in the duct is necessary
• Low noise levels
• Minimal mixing of the air

IntroductionThe Aircell range of supply & exhaust grilles are injection mouldedin self coloured white, Class ’’ 0 ’’ fire rated engineering polymer.Aircell S (Single deflection) and Aircell D (Double deflection)have individually adjustable vanes on a 19mm pitch to allow jetspread or deflection to be set within 45° of the duct axis.Aircell G (0° fixed blade) has horizontal 0° fixed blades on a20mm pitch.Aircell A (45° fixed blade) can be used as a wall or ceilingmounted grille, or alternatively they can be supplied with areduced stack for use as a door mounted transfer grille. (seeAircell T )Aircell T (45° fixed blade) are supplied as a pair of reducedstack Aircell A grilles for door mounting.Aircell E (Eggcrate) has a lattice core with a 13mm pitch and issuitable for all exhaust applications.All types are available in 5 standard sizes, plus an E600 whichhas been specifically designed for full ceiling tile replacement.The E600 has an overall size of 596mm x 596mm and for theNorth American market 603mm x 603mm overall ( E603 ) and forthe German Market, 621mm x 621mm overall ( E621 ).Waterloo’s Aircell products can be used in any airdistribution system where temperatures do not exceed50°C.

Grille Plenum Chambers
IntroductionCorrect selection and sizing of distribution plenumchambers is critical because grille air resistance isvery low relative to the distribution ductworkresistance. It is therefore recommended thatwhenever possible grilles are served by lowvelocity stub ducts from branch ducting systemsfitted with correct balancing controls.Where it is necessary to specify and use grilleplenums a generous allowance for commissionednoise generation should be made.

Room Temp = 20 °C
DT0 = 2 °C

G R ILL E SA complete range of products suitable for all wall, ceiling and applications. Most grilles are
made from aluminium, and have a range of ed or moveable blades designed to give
performance whilst remaining aesthetically pleasing to the eye. Grilles are made to customer
sizes and colours (PPM/G); standard colour is PPM9010 (20% Gloss White). This
range is complemented by the Aircell range of polymer Grilles and Di users.
DI FFUS E RSA complete range of products designed to be installed in various ceiling systems. Most di users
are made from aluminium, and can be ordered with or without plenum chambers for easy
connection to duct work. Di users can be ordered in customer (PPM/G) colours;
standard colour is PPM 9010 (20% Gloss White). This range is complemented by the Aircell
range of polymer Grilles and Di users.
ACT IVE A N D PASS IVE CHILLED BEAM SThe quality range of high output active beams, used for ventilated heating and cooling
applications. These units have 4 pipe coils to allow heating and cooling circuits to run
simultaneously, giving constant and responsive control. The design allows a large optimum
capacity, and also allows the customer to specify the nozzle type and pitch for individual
circumstances.
Active beams are made from steel to a large range of customer sizes and as such
are suitable for various di erent ceiling systems. Standard is PPM 9010, however other
(PPM/G) colours are available on request.
AIR VOLUME CONTR O L DAM P ERSA complete range of pressure independent Variable Air Volume and Constant air Volume
dampers. Most volume dampers are regulated with an electronic motor and sensors, and are
calibrated to customer before delivery. The constant air volume damper requires
no power source as it is controlled via a mechanical device it is also calibrated before delivery.
All volume dampers are made from Zintec plate and all units can be ordered with a single or
double (with insulation) skin.
EXTE RNAL LOUV RESA quality range of products for external wall applications. Made from aluminium, with birdscreen
or insect screen options. All louvres are made to customer spe ed sizes and (PPM/G)
colours; standard colour is PPM 9006
