Heavy mobile equipment carries substantial volumes of diesel, hydraulic oil and other flammable fluids under pressure. When a line ruptures near a hot exhaust or turbocharger, the conditions for a serious fire exist immediately. Foam-based fire suppression is the most appropriate technology for this class of risk — it directly addresses liquid hydrocarbon fires, cools the affected area and prevents re-ignition.
Basic System Architecture
Core System Components
- Foam concentrate cylinder (15L to 110L)
- Nitrogen pressurisation cartridge
- Detection system (MusterWire LHD or LOP)
- Pre-engineered stainless steel nozzle discharge network
How Foam Works on a Hydrocarbon Fire
Foam rapidly cools heated metal components and forms a blanket over the fuel surface that prevents vapour from escaping and cuts off the fire’s oxygen supply. This dual action is why re-ignition risk is significantly reduced compared to single-mechanism suppression approaches.
Detection: LHD vs LOP
Detection Method Comparison
- LHD (Linear Heat Detection): electrically monitored MusterWire at 68°C, 105°C or 180°C. Full diagnostics via the Muster Alarm Panel.
- LOP (Loss of Pressure): pneumatic tube that mechanically triggers discharge when ruptured by heat. No electrical power required.
Pre-Engineered vs Off-the-Shelf
Risk-Specific Engineering
Each Muster installation begins with a risk assessment identifying specific fire hazard zones, correct nozzle positions, required cylinder capacity, and appropriate detection temperature. The system is built to that specification, not adapted from a generic template.
Frequently Asked Questions
Mining excavators, dozers, haul trucks, wheel loaders, agricultural machinery, forestry equipment, waste compactors, and fixed applications like HPUs and gensets.
Fluorine-free foam (F3) contains no PFAS compounds. Muster’s 1% F3 concentrate is effective against Class B fires and complies with environmental protection policies.
Maintenance intervals align with AS5062:2022. Muster360 supports monitoring and documentation.
Yes. Multiple nozzles and cylinders can cover multiple risk zones simultaneously.
