Nozzle jet diffusers

Built fordistance.

Airports, pools, sports facilities, shopping malls, theatres, atriums: when air has to cross a large room, a nozzle throws it where ceiling diffusers cannot reach. EffectiV jet diffusers do it with a presence architects are willing to show.

The throw

A straight jet crosses the room. Angled nozzles cover it.

Nozzles concentrate the air into a jet that keeps its velocity over long distances, without relying on the Coandă effect of a ceiling. On a KOO panel every nozzle is aimed by hand: straight, the nozzles throw jets that surpass 100 ft; angled, they widen the pattern and shorten the throw to cover an area rather than a point.

Maximum throw

Parallel jets that keep their velocity to the far end of the room. To reach a distant zone, or to wash a curtain wall from the opposite wall.

Conceptual illustration only. It shows the principle, not a measurement: real temperatures, airflows and air quality vary from one room, system and building to the next.

The models

Four ways to throw air.

KAM-W

Surface-mount nozzle

An adjustable nozzle with hidden screws, for a wall or a ceiling. Its aluminium construction makes it the choice for pools and aquatic centres. Manual, actuator-controlled (KAM-W-M5) or thermodynamic (KAM-W-ACTIF).

KAM-D

Duct-mount nozzle

The same nozzle without the flange: it inserts directly into the opening of a round duct. The nozzle of open ceilings with exposed ductwork. Manual, actuator-controlled or KAM-D-ACTIF.

KOO

Multi-nozzle panel

One or two rows of 2 to 10 nozzles in a rectangular panel, two nozzle diameters, 32 sizes, 15 to 1065 cfm per diffuser. Every nozzle is aimed by hand: long throw or wide spread.

KOBE

Linear jet diffuser

A continuous long-throw slot in six widths. On the wall to cross a large room, in the ceiling to push air down along a glazed wall. Jet adjustable by ±30°.

Three ways to adjust

By hand, by actuator, or by temperature.

Manual

The base model: the jet angle is set by hand at installation or balancing.

Actuator (M5)

KAM-W-M5 and KAM-D-M5 take an on/off actuator that switches the jet between two angles from the control system: +30° in cooling and −30° in heating by default, or any other pair between −30° and +30°, specified when ordering and set at the factory.

Thermodynamic (ACTIF)

KAM-W-ACTIF and KAM-D-ACTIF tilt their own jet 30° down in heating and 30° up in cooling by default; any other pair of angles between −30° and +30° can be specified when ordering. No power, no controls.

Thermodynamic diffusers

SelectiV

Which angles for your room?

For the M5 and ACTIF versions, SelectiV models the jets in your room in cooling and in heating, so you can determine the optimal pair of angles before specifying it on the order.

Applications

Anywhere the room is bigger than a ceiling’s reach.

Airports and train stations
Pools and aquatic centres
Sports facilities
Shopping malls
Theatres and auditoriums
Atriums and lobbies
Car dealerships
Exhibition halls

KOO

The curtain wall case

To treat a large glazed wall, the reflex is to run ductwork to the top of the window and create an air curtain. A KOO panel on the opposite wall washes the same glass from a distance: often less duct, less labour, and real energy savings when the window is tall.
