When electric vehicle battery fires strike, you need immediate action. The Detachable EV Cooling Module from fourobot delivers enterprise-level fire suppression with proven results. Each single section covers 4 cubic meters with inverted umbrella water mist technology, while optional Potassium Oxide Aerosol Fire Extinguisher (POE) units handle 2 cubic meters per section. With a rated water flow of ≤0.3L/s, working pressure range of 0.6-1.0 MPa, and quick-attach modular design, this system lets your team push multiple connected sections under burning vehicles in seconds. Backed by 100 units in stock, 10 years of manufacturing expertise, and 20-day production cycles, we ensure you're ready when emergencies happen.

Your firefighting operations demand equipment that performs under extreme pressure. Our Detachable EV Cooling Module system gives you tactical advantages that traditional methods can't match.
Direct Access to Fire Source
Electric vehicle fires originate in bottom-mounted battery packs. This system slides directly beneath burning vehicles, targeting flames at their source. The 4cm ground clearance and omni-directional triangle wheel frame navigate tight spaces effortlessly.
Expandable Coverage Area
Connect multiple sections in seconds to match any vehicle size. From compact cars to heavy-duty trucks, you control the cooling area. Each 110cm section adds coverage instantly without tools or complex assembly.
Dual-Purpose Functionality
Your investment serves two critical roles: active fire suppression and thermal barrier creation. While extinguishing flames, the system simultaneously creates safe evacuation corridors by isolating fire zones.
Lightweight Mobility
At just 9.3kg per section, your team deploys the system quickly without heavy lifting equipment. The fiberglass push rod spans 3070mm when connected, keeping personnel at safe distances from heat and electrical hazards with 10kV insulation voltage protection.

Q: How quickly can I deploy this cooling module during an active fire?
A: The system deploys in seconds. Simply attach the push rod, connect to your water source, and push it under the vehicle. The omni-directional wheels navigate obstacles smoothly.
Q: Can I use agents other than water?
A: Yes, the system accommodates both water and gas fire extinguishing agents. This flexibility lets you adapt to different fire scenarios and regulatory requirements.
Q: What if the fire spreads across multiple vehicles?
A: Connect additional sections to expand your coverage area. Each section independently contributes 4 cubic meters of water mist coverage, scaling to match your situation.
Q: How do I maintain the equipment between uses?
A: The steel construction requires minimal maintenance. Inspect seals and connectors regularly, flush the system after use, and store in a dry location. Our manual provides detailed maintenance schedules.
Q: Is training required to operate this system?
A: Basic training is recommended. The intuitive design allows quick learning, but understanding water pressure management and tactical deployment improves effectiveness.
Q: Can this work with our existing fire robots?
A: Absolutely. Water Inlet Connector B specifically supports integration with fire robots, giving you automated deployment options for hazardous situations.
Q: What's the maximum temperature environment this system operates in?
A: The steel construction and fiberglass push rod withstand extreme heat. However, always maintain safe distances and follow your department's thermal exposure protocols.
