IFEX Gun Water Efficiency Proven by Arup Fire Engineer
6 Oct 2009
| For his Master Thesis at Victoria University, Arup Fire Engineer, David Sloan compared the amount of water used by an IFEX Gun to that used by a standard fire hose reel to extinguish flaming combustion and then glowing combustion. Compartment fire tests inside an ISO room as well as free-burning (open) fire tests were conducted in the modern fire testing facility of CESARE in Fiskville, Victoria. |

| The results from the tests are as follows: - For compartment fires, the reduction in upper layer temperature when using the IFEX gun is comparable to that when a fire hose reel is used but the latter requires at least 10 times the amount of water for a similar result. Depending on fire size, the IFEX gun uses 1/8th to 1/10th of the water used by a fire hose reel to finally cease flaming and glowing combustion. - For extinguishing "open" fires (1 to 2.5MW), the water used by the IFEX gun was 1/20th (or 5%) of that used by a fire hose reel in straight jet mode and 1/40th (or 2.5%) of that used by a fire hose reel in fog mode. |
