Hi Guys
I understand that Beetles and Kombi's are prone to fire. Blazecut is a perfect product for Automatic Fire Suppression.
Bulwark Fire Projects also sell these at various portals:

The Blazecut system doesn't really explode, imagine a 9kg propane cylinder, the gas is liquefied and if you open the valve the content expands into a gas. The same goes for Blazecut.
The Blazecut unit is filled with liquefied HFC-236fa. When the temperature rises to approx 120 degrees C, the liquid wants to become a gas. Wherever the heat is highest, the tube will melt and burst and the gas will be released. It then creates an inert environment in the engine bay or boot which prevents the fire from reigniting even if more fuel is introduced. Keep in mind that an engine bay or trunk is not 100% air tight and the inert environment will not last indefinitely.
HFC-236fa leaves absolutely NO residue.
The HFC-236fa gas does not remove the oxygen from the engine bay, it merely decreases the oxygen level to a percentage that will not sustain fire. The minimum extinguishing concentration of HFC-236fa is 5.9% for the 2m3 unit containing 0.5l of agent, the initial concentration will be about 11.6%. So more than enough gas for the volume. As the concentration oxygen is lowered the engine performance will go down. This is kind of like driving at higher altitudes. The % oxygen in air decreases the higher up you go. But this will only be temporary.
You can also buy the unit with a pressure switch which can be wired to a contactor that will disconnect the battery upon discharge. Which will then cut power to the fuel pump.
@splitbusahollic No single fire suppression/extinguishing system is perfect. At the very least, Blazecut gives you time switch off the car and get to your fire extinguisher should re-ignition occur.
You could argue that DPC fire extinguishers is most likely to be sufficient but consider that you have to open the hood, with a flammable liquid fire underneath, opening the hood can introduce more oxygen to the fire and flame up into your face/body. It does also leave residue which is terrible to clean up.
Refillable systems are crazy expensive that could cost in excess of R15k. The question is, is the risk of my vehicle catching fire high enough that paying R15k+ for refillable is justified, keeping in mind that the detection tube and agent to be replaced is hella expensive, not to mention annual servicing and hydrostatic testing of the cylinder every 10 years.
If you spend R10k on wheels, R5k on a fuel cell, R10k on a paint job etc, a R3400.00 "insurance policy" is not too bad.
