When electric vehicle fires strike, you need rapid response technology that works. The Detachable EV Cooling Module from fourobot delivers enterprise-grade fire suppression with proven performance metrics: each single section covers 4m³ with inverted umbrella-shaped water mist, while built-in Potassium Oxide Aerosol extinguishers add 2m³ coverage per section. Weighing just 9.3kg per unit, this modular system pushes easily under burning vehicles through ground clearances as low as 4cm. With 100 units in stock, a 20-day production cycle, and 10 years of manufacturing expertise, you get immediate deployment capability backed by CE and ISO certifications.

You face critical time pressure during electric vehicle battery fires. Our solution slides directly beneath burning vehicles to target overheated battery packs at their source. The lightweight design means your team can maneuver it quickly without heavy machinery.
The omni-directional wheel system moves smoothly across fire scenes. You don't struggle with positioning. Just push it into place and connect your water supply.
Every fire scenario is different. That's why our system connects multiple sections seamlessly.
Need to cover a compact sedan? One or two sections work perfectly. Dealing with an electric bus fire? Connect additional modules to expand your cooling and suppression zone.
Each section operates independently or as part of a larger array. You adapt to the situation in real-time.
Water mist alone isn't always enough. Our EV Cooling Module combines two proven firefighting methods:
Water Mist System: Six sprinklers per section create fine mist that cools rapidly while using minimal water. Rated flow of 18L/min means you conserve water resources during extended operations.
Potassium Oxide Aerosol (POE): Two built-in extinguishers per section actively eliminate flames through chemical suppression. They activate at temperatures ≥180°C, responding automatically to thermal threats.
This dual approach addresses both temperature reduction and flame elimination simultaneously.

Q: What is a Detachable product?
A: It's a modular fire suppression system specifically designed for electric vehicle battery fires. Unlike fixed systems, you can quickly deploy it beneath burning vehicles to cool overheated battery packs and eliminate flames using water mist and chemical suppression.
Q: How many sections do I need for different vehicle types?
A: It depends on vehicle size. Compact cars typically need 1-2 sections. SUVs and vans work well with 2-3 sections. Electric buses and trucks may require 4 or more sections. Each section covers 4m³ with water mist plus 2m³ with aerosol suppression.
Q: Can firefighters operate this safely during active electrical fires?
A: Yes. The fiberglass push rod insulates up to 10kV, keeping operators at a safe 3-meter distance. The omni-directional wheels allow positioning without direct contact with the vehicle.
Q: What maintenance does the system require?
A: Regular inspection of connectors, wheels, and pressure ratings. The steel construction resists corrosion. POE extinguisher cartridges should be checked according to local fire equipment regulations. Our support team provides detailed maintenance schedules.
Q: Does this work with existing fire robot systems?
A: Absolutely. Water Inlet Connector B specifically interfaces with robotic fire suppression platforms. You can integrate it into automated response systems or operate it manually with the push rod assembly.
Q: What's the minimum ground clearance needed?
A: Approximately 4cm (1.5 inches). This fits under most modern electric vehicles. If you encounter lower clearances, contact our team about customization options.
Q: How quickly can I get units delivered internationally?
A: Air freight typically takes 5-7 days to major international airports. Sea shipping ranges from 15-45 days depending on destination. We expedite customs documentation to minimize delays.
Q: Can I get training for my fire response team?
A: Yes. We provide operational training materials with every order. For larger deployments, we can arrange specialized training sessions through our local agent network.
