Industry Risk
Fire Exposure in Heavy-Duty Mobile Equipment
Earthmoving and mining machinery operates under continuous mechanical stress and elevated thermal loads. Engines, hydraulic systems and fuel components are exposed to extreme temperatures, often in confined compartments.
Equipment such as:
- Excavators
- Wheel loaders
- Bulldozers
- Dump trucks
- Drilling rigs
operates in remote environments where manual fire response may be delayed.
Fire incidents in these sectors can result in:
- Severe equipment damage
- Extended operational downtime
- Project delays
- Safety exposure for operators
- High financial impact
Common Ignition Sources
Typical Fire Hazards in Construction and Mining Equipment
Heavy-duty machinery combines heat, pressure and combustible fluids in close proximity. In remote or underground operations, early suppression is essential to prevent full machine loss.
High-Heat Engine Components
Turbochargers, exhaust manifolds and engine blocks generate extreme temperatures during heavy load cycles.
Hydraulic Oil Ignition
High-pressure hydraulic systems may leak onto hot surfaces, increasing ignition risk.
Fuel System Leaks
Diesel and lubricants can ignite when exposed to overheated components.
Accumulated Debris and Dust
Combustible material buildup around engine compartments increases fire propagation potential.
Protega Fire Suppression Systems
Designed for Harsh and Demanding Environments
Protega designs automatic fire suppression systems specifically for heavy-duty mobile equipment.
Systems are configured to protect:
- Engine compartments
- Hydraulic pump areas
- Fuel systems
- Electrical enclosures
Upon exposure to critical temperature, the system activates automatically, without operator intervention.
The fully pneumatic configuration operates independently from the machine’s electrical system, ensuring protection even during electrical failure.
How Our Systems Work
Direct and Indirect Detection Technologies
Protega fire suppression systems can be configured as direct or indirect systems depending on enclosure layout and suppression strategy.
Protega systems utilize a heat-sensitive polymer detection tube that remains continuously pressurized (approx. 20 bar).
When exposed to flame or critical radiant heat:
- The polymer softens at the hottest point
- The tube ruptures locally
- System pressure drops immediately
- The cylinder valve opens pneumatically
- The extinguishing agent is discharged
This configuration:
- Requires no external power
- Operates autonomously
- Is highly resistant to vibration
- Is suitable for harsh vehicle environments
In a direct system, the pneumatic detection tube performs a dual function: it serves both as the fire detection element and as the discharge line for the extinguishing agent.
The heat-sensitive polymer tube is routed throughout the protected compartment near identified risk zones. The tube remains continuously pressurized (approximately 20 bar) and forms a closed detection loop within the enclosure.
When exposed to flame or critical radiant heat:
- The polymer softens at the hottest point
- The tube ruptures locally
- System pressure drops immediately
- The cylinder valve opens pneumatically
- The extinguishing agent is discharged directly through the rupture point
Because discharge occurs exactly at the highest temperature location, suppression is highly localized and immediate. This configuration provides fast response with minimal system complexity and no reliance on electrical power.
In an indirect system, the pneumatic detection tube functions solely as the fire detection element. It does not discharge the extinguishing agent.
The pressurized detection tube is routed through the protected compartment near identified risk areas. When thermal activation occurs, it pneumatically triggers the suppression cylinder without acting as the discharge line.
When exposed to flame or critical radiant heat:
- The polymer softens at the hottest point
- The tube ruptures locally
- System pressure drops immediately
- The cylinder valve opens pneumatically
- The extinguishing agent is discharged through pre-engineered nozzles
Unlike the direct configuration, the extinguishing agent is not released through the rupture point itself. Instead, it is distributed via strategically positioned discharge nozzles engineered according to enclosure geometry and airflow patterns.
This enables controlled and volumetric suppression across larger or segmented compartments.
Agent selection
Suppression Agents for Recycling & Material Handling
Heavy-duty mobile machinery typically combines Class A, B and C fire risks within a confined engine compartment.
ABC Dry Powder
Primary Heavy-Duty Configuration
ABC dry powder is widely used in construction and mining equipment due to its rapid knockdown capability and broad fire class coverage.
Technical characteristics:
- Effective against Class A, B and C fires
- Rapid flame knockdown
- Suitable for fuel and hydraulic oil risks
- Proven performance in vehicle applications
- Compatible with fully pneumatic activation systems
ABC powder provides immediate suppression in high-risk engine and hydraulic compartments.
Dual Agent System (Powder + Foam)
Enhanced Suppression for High-Risk Operations
For high-load and high-value equipment, Protega can configure dual agent systems combining dry powder and foam.
This configuration delivers:
- Immediate flame knockdown through powder discharge
- Surface sealing and cooling through foam application
- Reduced re-ignition risk in fuel and hydraulic systems
Technical characteristics:
- Combined rapid knockdown and cooling effect
- Enhanced protection against liquid fuel fires
- Reduced re-ignition probability
- Engineered for high-load industrial applications
Dual agent systems are particularly suitable for mining machinery, underground equipment and high-value construction fleets.
