/ Otter-X EV Cooling Module

Battery extinguishing system

This Detachable EV Cooling Module is a professional fire-fighting accessory for electric vehicle emergencies, consisting of a Single Section, standard Water Inlet and Outlet Connectors, and a user-friendly Push Rod. It is compatible with water and gas fire extinguishing agents, and can be smoothly pushed into the chassis bottom of a burning vehicle to perform direct cooling on battery packs and eliminate open flames thoroughly. Each single section sprays inverted umbrella shaped water mist that covers 4 cubic meters of space, while the Potassium Oxide Aerosol Fire Extinguisher (POE) integrated in each section covers 2 cubic meters. The detachable and quick-connect design lets multiple sections be attached to each other in seconds for large-scale cooling and fire suppression tasks. It is widely applicable for burning vehicle cooling and fire extinguishing, and can also be used to build isolated safe passages for fire escape and rescue.

What Makes Our Battery Fire Suppression System Different?

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:

  • Push-and-go deployment using fiberglass rods with 10kV insulation protection
  • Omni-directional triangle-frame wheels that navigate tight spaces effortlessly
  • Only 4cm ground clearance required to slide beneath burning vehicles
  • Compatible with both water mist and optional Potassium Oxide Aerosol (POE) suppressants

You can use it alone for smaller incidents. Or attach multiple modules for large-scale cooling operations. The flexibility adapts to your emergency scenario.

Why Fire Departments Trust Our EV Fire Solutions

Rapid Deployment Saves Lives

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.

Flexible Configuration for Any Scenario

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.

Built for Extreme Conditions

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.

Application Scenarios For Battery extinguishing system

Emergency Response Teams

Fire departments across urban areas face increasing EV incidents. Our system fits standard fire trucks and deploys without special training.

Frequently Asked Questions

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.
