“It’s All About the
………………TUBE”
• Linear, pneumatic flame detection
• Bursts at 212°F (100°C)
• Tubing can be the detector & the piping
network
• Tubing is durable and flexible
• Tubing is not conductive or corrosive
• Good for harsh chemical environments

Direct Low Pressure (DLP)
System
• Tubing is used as a
detector and delivery of
agent from cylinder
• Valve is a X-over only to
allow for connection of
the tubing to cylinder
• 4 ports on this valve
for gauge, P/S, Ball
Valve and cylinder
Max
3.3 ft /
layer
• Discharge time is limited
due to the x-sectional area
of the ball valve orifice.
