1. EXHAUST KIT DESCRIPTION
About this manual
This manual describes the Heat Exhaust kit with part number R9843115 and the way to install it on a projector.
Overview
•
•
•
1.1 Domain of application
What can be done ?
The Heat Exhaust kit allows to connect an external tube system to the projector in order to transport the exhaust hot air outside the
projection area.
Each projector has 2 exhausts:
1. left exhaust;
2. right exhaust.

Exhaust location
One can decide to connect only one or both exhausts.
Projector range
The Heat Exhaust kit is intended to be used on the following projector ranges:
•
•
•
(Galaxy) NH-12;
(Galaxy) NW-12;
Galaxy NW-7.
1.2 Specifications
Heat dissipation per projector
The maximum heat dissipation of the projector when it runs at full power is 2800 W or 9560 BTU/h. This value can be different,
depending on the power rate of the lamp (i.e. Economy mode or Normal mode).
Outlet temperature
The maximum temperature of the air at the outlet is 60° C when the projectors run at full power and assuming the environmental
temperature to be 20° C maximum. All elements in the air extraction need to resist at least a temperature of 60° C for long duration.
Air speed
For acoustical reasons, an air speed of 6 m/s is typically recommended in an office/auditorium environment. In a display system
where the projectors and the collector are not situated inside the projection room, the air speed in the tubes between projector outlet
and "collector" tube can be slightly higher.

1. Exhaust kit description
Flow rate
The flow rate varies, as the speed of the internal fans changes depending on the power rate of the projector and depending on the
ambient temperature. The maximum flow rate is 50 l/s per projector. The airco can be designed to extract 50 l/s per projector at all
time.
The following table lists the air flow at both exhausts in different lamp power modes:
Exhaust air flow
Economy lamp mode
3,3 l/s
20,3 l/s
Normal lamp mode
6,4 l/s
1
2
31,3 l/s
Outlet tube
The external diameter of the outlet tubes is 100 mm, which matches the common size of 100 mm for flexible extraction pipes. For a
flow rate of 50 l/s, this results in an air speed of 6,4 m/s.
The extraction pipes are not included in this kit
Extraction control
No air extraction control is required. It is no problem that air is sucked through the projectors even when they are switched off.
Please note that heat dissipation in the room is obviously less when all projectors are switched off. For good
stability of the system, the projection room should be kept to the same temperature level, no matter if the
projectors are on or off. Therefore the airco must be controlled in some way by temperature sensors in the
projection room.
