Be very careful mounting anything on the rollbar. In the event of an accident, it could break loose and hit someone in the back of the head.

Proteng question
 
Fasteagle, Aren't you concerned that the temp under the housing will get over 194 degrees? Have you talked to the people at Proteng about this? what did they say? I saw they had one mounted in a Cessna 182.

Fire extinguisher
 
Allen,

Yes I did. They use these in race cars, airplanes, RV?s, workshops, etc. Any place where there is heat or a fire source or potential for fire. It is used in high heat close quarters areas. If memory is correct I want to say 350 degrees is where it sets off but I may be incorrect with this. There are videos giving examples of a fire near then it setting off automatically, which very efficiently and completely put out the fire.
Contact Nichole Wheeler at Proteng and she will kindly address all your concerns.
They gave a very good presentation at our last EAA meeting and we were all impressed. It?s a great safety device with many applications. Not to stir any negative comments, but my opinion is that most small fire extinguishers are just a false sense of security. Sure, better than nothing but not equal to or certainly not better than this.
I had a friend crash in an experimental years ago. He survived the impact only to be trapped inside. The roofers several houses away witnessed the crash and could hear him screaming for several minutes as he burned to death. No one was able to get to him fast enough. Horrible death I want no part of. Safety is an attitude as we are all taught.

From the Proteng website:

How does the PROTENG? fire suppression device work?

The system is fully automatic and responds to increasing temperatures. At temperatures of 158?F (Standard) or 194?F (Heavy Duty) and or contact with direct flame, the tube ruptures, releasing the non-toxic agent and thus extinguishing the protected area.



What if there?s contact with skin or eyes? What if it?s inhaled?

If contact with skin or eyes, immediately flush with plenty of water for at least 15 minutes. Take off contaminated clothing immediately and wash before re-use. If inhaled, remove from exposure to fresh air and lie down. Consult a physician.

Well there ya go.

Interesting concept, pressurized fire suppressant similar to Dupont FE-36 in a hose that will rupture at a certain temperature.

PCT and info on Dupont FE-36 linked below.

I'd sure like to see a test of one of these systems under the cowling. You know, take a scrapped engine block, run some fuel hoses the way they'd run, put it inside a cowling, *blast 170 knot winds at it*, and ignite a fire and a broken hose.

I just can't see that this would work with an engine fire in flight. On the ground, maybe (but if that big fan out front is turning and blowing air into the cowling?).

Race cars are *not* the same thing...something on fire? You can stop the vehicle (or it may have already stopped by virtue of smacking into something, which caused the fire in the first place).

Until you turn off the fuel flow (glider pilot). I don?t think any system will put out a fire in flight. I am assuming that with fuel off 99% of the fuel source is eliminated. The extinguisher might help with whatever is left that is combustible.
Anyone have any experience or knowledge of how a fire in flight reacts to shutting off the fuel flow?

PROTENG® fire suppression Sounds like a good concept but I found no pricing on their website. Any cost to share with the group Fasteagle?

FYI - if you haven't seen Vic's firex thread: "Don't use ABC fire extinguishers!"
