/ Otter-X EV Cooling Module

EV Firefighting Equipment

This professional Detachable EV Cooling Module is made up of a Single Section, dedicated Water Inlet and Outlet Connectors, and a sturdy Push Rod, serving as a key accessory for electric vehicle fire rescue. It adopts water and gas as applicable extinguishing media, and can be conveniently pushed into the bottom of a burning electric vehicle to target battery pack cooling and flame elimination. Each single section generates special inverted umbrella shaped water mist with a coverage area of 4 cubic meters, and the matching Potassium Oxide Aerosol Fire Extinguisher (POE) covers 2 cubic meters per section. The modular detachable design allows multiple sections to be connected quickly and firmly for large-area cooling and fire fighting. Apart from extinguishing burning EVs and cooling key components, it can also be used to isolate fire scenes and build safe escape paths for trapped personnel.

Why Fire Departments Choose Our EV Firefighting Equipment

Reach the Source of the Fire

Traditional fire suppression methods struggle to access lithium-ion battery packs located deep within vehicle chassis. Our cooling module solves this problem effectively. The slim 4cm profile allows you to push the unit directly under burning electric vehicles, targeting the actual ignition source rather than surface flames.

Modular Design for Scalable Coverage

You can connect multiple sections quickly and firmly. Each section works independently or as part of a larger system. This flexibility means you adapt to different vehicle sizes and fire intensities without carrying multiple specialized tools.

Omni-Directional Deployment

The triangular omni-wheel frame lets you maneuver from any angle. Tight parking garages, narrow loading docks, or cluttered accident scenes won't stop you from positioning the EV Firefighting Equipment exactly where it's needed.

Water Mist Technology

Six precision sprinklers per section create fine water mist that cools battery cells efficiently while using less water than conventional methods. The rated flow of 18L/min at 0.8 MPa work pressure delivers effective thermal management without flooding confined spaces.

Optional Aerosol Fire Suppression

Add Potassium Oxide Aerosol Fire Extinguishers (POE) for flame elimination. Each section accommodates two POE units covering 2 cubic meters, combining cooling and chemical suppression for comprehensive fire control.

Real-World Applications

Underground Parking Facilities

You face unique challenges in confined spaces. Low ceilings prevent traditional equipment access. Our module's compact design fits where fire trucks cannot enter, isolating burning vehicles and preventing fire spread to adjacent cars and building structures.

Vehicle Loading Docks

Logistics facilities with charging stations need rapid response capabilities. Deploy the cooling system to stabilize battery modules experiencing thermal runaway during charging cycles, protecting workers and maintaining operational continuity.

Emergency Escape Path Creation

Beyond extinguishing flames, you can use the water mist system to create safe corridors for trapped personnel. The cooling effect reduces ambient temperatures and visibility-impairing smoke, facilitating rescue operations.

Frequently Asked Questions

Q: How does this equipment differ from traditional fire hoses?

A: Traditional hoses cool vehicles from the outside. Our system goes directly underneath to target battery packs where thermal runaway occurs. The water mist technology uses less water while achieving better cooling efficiency in the confined battery compartment.

Q: Can first responders safely operate this near high-voltage batteries?

A: Yes. The fiberglass push rod provides 10kV insulation voltage protection. The water delivery system operates at safe working pressures, and the omni-wheel design lets responders maintain distance while positioning the equipment.

Q: What if the fire reignites hours later?

A: Lithium-ion fires are notorious for reignition. Our continuous cooling capability allows you to maintain thermal management as long as needed. Connect multiple sections for extended coverage duration until the battery temperature stabilizes completely.

Q: How many sections do I need for a typical passenger EV?

A: Most passenger vehicles require 1-2 sections. Larger EVs like buses or trucks may need 3-4 sections. The modular design lets you scale coverage based on vehicle size and fire intensity.

Q: Is special training required to operate this module?

A: The intuitive design requires minimal training. Connect water supply, push the unit beneath the vehicle using the insulated rod, and activate water flow. Your team can become proficient after one hands-on session.

Q: What maintenance does this equipment need?

A: Inspect sprinkler nozzles and wheel assemblies after each use. Flush the water system to prevent mineral buildup. Store in a dry environment. We recommend annual professional inspection, which our local agents can provide.

Q: Can this work with our existing fire robots?

A: Absolutely. Water Inlet Connector B is specifically designed for fire robot integration. The DN40 connectors provide standard compatibility with most robotic firefighting systems.

Q: What's the typical response time for replacement parts?

A: Our global agent network stocks common components. Expect 3-5 business days for standard parts in most regions. Critical components can be expedited when necessary.
