Nozzle and Discharge Pipe Requirements
Specially designed High Throughput Powder Diffusers are used with the FTILPINTHTBI System, this type of nozzle
decreases discharge time and increases the spread of dry powder. The baseline engine compartment must be
designed using at least 3 nozzles to suit hazard configuration of a 4m
3
engine compartment.
A standard nozzle layout would include nozzles being installed at the top of the engine compartment roof facing
downwards in a pendant position. One nozzle shall be located above the exhaust manifold in the region where oil is
most likely to spill. Another nozzle shall be in the region of prominent hazards.
Each cylinder valve is equipped with 3 discharge ports (DP). All three discharge ports are to be used onto the engine
compartment.

Firetrace Detection/Actuating/Discharge Tubing
For the FTILPINTHTBI System, the Firetrace® tubing is used as a combination for heat detection, system activation
and system discharge.
The detection/actuation/discharge tubing is heat sensitive and in a fire situation is designed to rupture at any point
along the tube upon direct flame impingement or at high temperatures associated with fire conditions. The Firetrace®
detection tubing will burst when subjected to temperatures above 120°C (248°F) and form a diffuser where a
percentage of the Dry powder will be deployed.
The maximum length of Firetrace® detection tubing that can be used for FTILPINTHTBI Systems is 20m.
