When electric vehicle fires strike, seconds matter. Fourobot presents our enterprise-grade Battery extinguishing system – the Detachable EV Cooling Module (Otter-X). This professional firefighting solution is specifically engineered to tackle thermal runaway incidents in lithium-ion battery packs. With a lightweight design averaging just 9.3kg per section, our system deploys in seconds and covers 4 cubic meters per module through inverted umbrella-shaped water mist spray. Backed by 10 years of manufacturing expertise and certified to international standards (CE, ISO, TAF, TELEC), we maintain 100 units in stock with a rapid 20-day production cycle for small orders and 5×12 hour response time.

Traditional fire extinguishers fail against EV battery fires. You need specialized equipment that understands thermal runaway.
Our Detachable EV Cooling Module solves this challenge. The modular design lets you connect multiple sections within seconds. Each section works independently or integrates with fire robots for remote operation.
The system features:
You can use it alone for smaller incidents. Or attach multiple modules for large-scale cooling operations. The flexibility adapts to your emergency scenario.

Time is your enemy during battery fires. Our Battery extinguishing system deploys faster than traditional methods. Simply push the module under the vehicle using insulated rods. Water mist activates immediately at rated pressure.
The 6 strategically positioned sprinklers create overlapping coverage zones. This ensures no hot spots remain unaddressed.
Standalone Operation: Perfect for parking garage incidents or roadside emergencies. Connect Water Inlet A and push manually.
Robot Integration: For hazardous environments like tunnels or chemical plants, attach to your fire robot via Water Inlet B. Control from safe distance.
Scalable Response: Connect 2, 3, or more sections for large commercial vehicles or buses. Each module adds 4m³ of coverage area.
Electric vehicle fires generate intense heat and toxic gases. Your equipment must withstand harsh conditions.
Our steel construction handles rough terrain. The powder-coated finish resists corrosion from extinguishing agents. Omni wheels maintain mobility even on uneven surfaces.
The fiberglass push rod provides electrical insulation up to 10kV. This protects firefighters from high-voltage battery systems.
Fire departments across urban areas face increasing EV incidents. Our system fits standard fire trucks and deploys without special training.
Bus depots and delivery vehicle facilities need on-site fire suppression. Stock units in your maintenance bay for immediate response.
Multi-level parking garages and charging stations represent concentrated risk zones. Install units at strategic access points.
Underground passages require remote-operated solutions. Integrate with existing fire robots for unmanned intervention.
Warehouses using electric forklifts and AGVs benefit from quick-deployment fire barriers. Create safe evacuation corridors while cooling burning equipment.
We don't just claim quality. We prove it through international certification.
CE Certification: European safety standards compliance ensures global market acceptance.

ISO Standards: Our manufacturing processes meet rigorous quality management requirements.

Q: How does this differ from traditional fire extinguishers for EV fires?
A: Standard extinguishers can't penetrate battery pack enclosures. Our system slides directly beneath the vehicle chassis. Water mist reaches battery cells where fire originates. The cooling effect prevents thermal runaway propagation between cells.
Q: Can I use this on vehicles with low ground clearance?
A: Yes. The module requires only 4cm clearance. This accommodates most passenger EVs and many sports cars. For extremely low vehicles, the push rod lets you angle the module for insertion.
Q: What pressure do I need from the water source?
A: Rated performance occurs at 0.8 MPa (approximately 116 PSI). The system functions effectively between 0.6-1.0 MPa. Most fire truck pumps easily provide this pressure range.
Q: How many sections do I need for a bus fire?
A: A standard electric bus battery pack spans 6-8 meters. We recommend 3-4 connected sections for comprehensive coverage. Each section covers approximately 2 meters of length with overlapping spray patterns.
Q: Does the optional aerosol extinguisher pose environmental concerns?
A: Potassium Oxide aerosol has zero Ozone Depletion Potential. The solid particulate settles quickly and can be swept up after use. It's significantly more environmentally friendly than halon alternatives.
Q: Can this create safe escape routes in tunnels?
A: Absolutely. Deploy sections to form a water mist barrier between the fire and evacuation paths. The cooling effect reduces radiant heat and toxic gas spread. This creates a temporary safe corridor for passengers and emergency personnel.
Q: What maintenance does the system require?
A: Quarterly visual inspection of connectors and wheels. Annual pressure testing of the distribution system. Replace damaged spray nozzles as needed. The robust steel construction minimizes maintenance requirements compared to complex electronic systems.
Q: Do you provide training for first-time users?
A: Yes. We supply operation videos and user manuals with every order. For bulk purchases, we can arrange on-site training through our agent network or virtual training sessions with your team.
At fourobot, we recognize that fire suppression equipment represents more than a purchase. It's an investment in life safety.
Our company culture emphasizes continuous improvement and customer focus. We invest in skills training for our team. We maintain transparent communication throughout your order process. Performance-based quality controls ensure every unit meets our standards.
The electric vehicle revolution brings new challenges. Battery fires behave differently than conventional vehicle fires. You need equipment designed specifically for electrochemical hazards.
Our Battery extinguishing system combines practical engineering with real-world testing. The detachable modular design wasn't created in isolation. We collaborated with fire safety professionals to understand deployment challenges. The result is a tool that works when lives depend on it.
