Industry Risk
Fire Exposure During Harvest Operations
Agricultural machinery operates under elevated fire risk conditions, particularly during harvest season. Combines, forage harvesters and tractors generate high engine temperatures while operating in dry crop environments.
Field fires can escalate rapidly and may result in:
- Loss of machinery
- Crop damage
- Spread to surrounding land
- Operational interruption during critical harvest windows
Early detection and autonomous suppression are essential in limiting fire propagation.
Common Ignition Sources
Typical Fire Hazards in Agricultural Machinery
Harvest environments combine heat, dry organic material and mechanical stress. Dry crop residues and dust significantly increase fire propagation potential.
High-Heat Engine Operation
Combines and tractors operate under heavy seasonal load, generating elevated engine and exhaust temperatures in confined compartments.
Crop Dust Accumulation
Dry organic material accumulates around engine and exhaust components, increasing ignition and fire propagation risk.
Hydraulic Oil Under Pressure
Hydraulic systems used for harvesting and lifting may leak onto overheated components.
Continuous Harvest Operation
During peak harvest periods, machines operate for extended hours, reducing inspection intervals and increasing cumulative thermal stress.
Protega Fire Suppression Systems
Designed for Remote and Seasonal Operation
Harvest operations often take place in remote environments where immediate manual fire response is limited. Automatic suppression significantly reduces escalation risk before fire spreads to surrounding crop material.
Protega systems are configured to protect:
- Engine compartments
- Hydraulic systems
- High-temperature mechanical zones
- Enclosed technical components
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 continuous protection during remote operation.
Designed for Harsh Field Conditions
Built for Dust, Vibration and Temperature Exposure
Agricultural equipment operates in environments exposed to vibration, dust and fluctuating temperatures.
Protega systems are engineered to withstand:
- Crop dust accumulation
- Continuous vibration
- Outdoor temperature variation
- Mechanical shock
Compact components allow integration within confined engine compartments of modern agricultural machinery.
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 Agricultural Machinery
Heavy-duty mobile machinery typically combines Class A, B and C fire risks within a confined engine compartment.
ABC Dry Powder
Primary Port Equipment Configuration
ABC dry powder provides rapid knockdown across multiple fire classes commonly present in diesel-powered terminal equipment.
Technical characteristics:
- Effective against Class A, B and C fires
- Rapid flame knockdown
- Suitable for fuel and hydraulic oil risks
- Proven in heavy-duty mobile environments
- Compatible with fully pneumatic activation systems
ABC powder provides immediate suppression in high-risk engine and hydraulic compartments.
Dual Agent System (Powder + Foam)
Enhanced Protection for High-Value Equipment
For high-value container handling equipment operating continuously, Protega can configure dual agent systems combining dry powder and foam.
This configuration provides:
- 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.
