- 70,000+ systems installed worldwide  - Fogmaker is the leading fire suppression supplier in the European and Australian bus market. Fogmaker is the preferred system for Mercedes & Volvo in Europe. - UK overview: Total fleet of ~600 with Fogmaker, 33 known incidents over 4 years with all being suppressed without issue and minimal damage.

- Australia, we have installed well over 1000+ Government Buses with Fogmaker and we have to date had approximately a dozen thermal events with buses fitted with the System. In all cases, the system has detected & suppressed the fires with little or no damage with exception to “what” caused the initial fire (ie cracked fuel rail, electrical arcing, broken lines / hoses, debris etc.)

- Over 1000 buses in US and Canada are now using Fogmaker – UL Listing was requested by some larger customers.

- CNG application in Tempe with NFI, very happy to date and positive result on incident

- Testing method was that of SBF128 (Full-scale extinguishing trials of water mist in a bus fire)

- SBF128 is a Swedish test protocol executed by SP (Science Partners) and tied to the Insurance Institute

- Overview of the test- 20 min preheat of bus (15 @ idle, 5 with throttle)- 7 pounds of woodchips presoaked for 24 hours with a diesel / oil mixture placed throughout engine - Cotton rags presoaked with above mixture also placed throughout - 1.5 liters of Diesel / oil sprayed throughout- Ignite engine compartment with torch- Close and burn for 20 seconds - Manual activation of the fire suppression system- Continue to run engine / fan at idle speed

- Attacks all 3 elements of the fire triangle:

- Heat: Water mist cooling effect.

- Fuel: AFFF (Foam) blankets the fuel

- Oxygen: Steam chokes out the oxygen

- Longer cooling & suppressing time

- 40-70 seconds continuous

- Re-flash prevention

-Hot surfaces are cooled below flash temps

-Any remaining fuel is covered by the

AFFF (Foam)
