SnakE® 4 Solid: aktive Kühlung unter der Brandbegrenzungsdecke

SnakE® 4 Solid ist die hitzefeste Variante des modularen Löschsystems von Rescuevation. Vier V4A-Düsenmodule sind über starre V4A-Rohre und drehbare T-Stücke verbunden, ohne schmelzbare Schläuche. Entwickelt für die aktive Unterbodenkühlung unter Brandbegrenzungsdecken wie z.B. von VLITEX.

vfdb Excellence Award 2025.

  • Hohe Hitzebeständigkeit: komplett aus V4A-Edelstahl, keine schmelzbaren Schlauchverbindungen unter der Decke.
  • Aktive Kühlung statt nur Begrenzung: Brandbegrenzungsdecken halten den Brand abgedeckt, SnakE® Solid kühlt den Akku darunter aktiv.
  • Drehbare T-Stücke: Ausrichtung der Düsen flexibel anpassbar, obwohl die Rohrverbindungen starr sind.
  • Storz-D-kompatibel: lässt sich mit SnakE® 4 Standardmodulen kombinieren.
  • Eurobox-verlastet: 60 × 40 × 12 cm, Gewicht und Maße wie SnakE® 4, kein zusätzlicher Geräteraum nötig.

"Lösch-"Decken begrenzen, sie kühlen nicht

Brandbegrenzungsdecken wie die VLITEX E-AUTO PREMIUM halten einen brennenden Akku unter Verschluss, reduzieren Rauchausbreitung und schützen die Umgebung. Was sie nicht tun: den Akku aktiv kühlen. Die Energie bleibt im Speicher, die Zelltemperatur sinkt nicht, ein laufender Thermal Runaway entwickelt sich unter der Decke ungestört weiter. Ohne Kühlung wartet die Feuerwehr darauf, dass das Fahrzeug ausbrennt, mit Decke nur kontrollierter.

Die Lösung: SnakE® 4 Solid

Vier V4A-Düsenmodule sind über vier V4A-Rohrsegmente und zwei T-Stücke mit drehbaren Kupplungen zu einer mechanisch festen Einheit verbunden. Keine flexiblen Schläuche im Lastpfad. Die Wasserzuführung läuft weiterhin über Storz-D, der Anschluss an die vorhandene Wasserversorgung bleibt unverändert. Das System wird in die Mulde des Fahrzeugs geschoben, die Decke kommt darüber. Pro Modul ca. 20 l/min bei Vollkegeldüse, fein zerstäubt direkt auf den Unterboden.

Die drehbaren T-Stücke erhalten die taktische Flexibilität: Sprührichtung jedes Moduls bleibt einstellbar, obwohl die Rohrverbindungen starr sind. SnakE® Solid und SnakE® 4 nutzen dieselbe Storz-D-Schnittstelle. Beide Varianten lassen sich kombinieren, etwa Solid unter der Decke, Standard außen für Objektkühlung.


  • Tesla-Rettungsdatenblatt empfiehlt für Hochvoltbatterien die direkte Unterbodenkühlung mit Wasser. SnakE® Solid macht das unter der Decke technisch möglich.

Kombination mit VLITEX-Brandbegrenzungsdecken

VLITEX GmbH aus Bayreuth ist ein etablierter Hersteller von Brandbegrenzungsdecken für Fahrzeug- und Akkubrände. Die VLITEX E-AUTO PREMIUM ist nach DIN SPEC 91489 zertifiziert, dauerhaft bis 1.000 °C, kurzzeitig bis 1.750 °C temperaturbeständig.

Wie das Zusammenspiel funktioniert:

  1. Brandbegrenzungsdecke wird über das Fahrzeug gezogen, schließt den Brand ein.
  2. SnakE® Solid wird parallel oder vorab unter den Unterboden geschoben.
  3. Wasser marsch, Akku wird aktiv unter der Decke gekühlt.
  4. Wärmebildkamera kontrolliert die Temperaturentwicklung von außen.

Die Decke begrenzt den Brand und schützt die Umgebung. Solid bringt das Wasser dorthin, wo das Strahlrohr allein nicht hinkommt. Beide Systeme arbeiten zusammen, nicht gegeneinander.

Rescuevation als Bezugsquelle: Auf Anfrage liefern wir auch VLITEX-Decken passend zu SnakE® Solid mit aus. Sprechen Sie uns auf das Solid-plus-Decke-Bundle an.

Frequently asked questions

When do I need SnakE® Solid instead of SnakE® 4?

Whenever you work with fire containment blankets or the system is used under intense radiant heat. Solid has no meltable components in the load path. Without blanket use, SnakE 4 is the more universal and slightly more cost-effective choice.

Can I combine SnakE® Solid with my existing VLITEX blanket?

Yes. The blanket contains the fire while Solid actively cools underneath. Both systems are independent and are used in parallel. Requirement: sufficient ground clearance to slide Solid under the underbody before or while the blanket is applied.

Does this also work with blankets from other manufacturers?


Technically yes, provided the blanket reduces radiant heat and enough space remains for Solid underneath. The combination with VLITEX has been tested and documented; blankets from other manufacturers may also be suitable based on the same application logic. We will discuss specific recommendations in a consultation.

Can SnakE® Solid and SnakE® 4 be combined in one operation?

Yes. Both use the same Storz D interface. You can position Solid under the blanket and work with SnakE 4 outside in parallel, for example to cool adjacent vehicles.

How heat-resistant is V4A?

V4A (1.4571 / 1.4404) remains dimensionally stable well above 800 °C and is acid-proof and corrosion-resistant against fire gases, battery contamination, and salt water. In the realistic operating range under a fire containment blanket, the system remains mechanically strong

Does SnakE® Solid prevent a thermal runaway?

This cannot be guaranteed. Solid supports cooling in the underbody area and makes the water application called for in the AGBF recommendations technically feasible. Whether a thermal runaway occurs or is stopped depends on the damage pattern, water supply, and situation.

How does maintenance compare to SnakE® 4?


Lower maintenance. Solid has no hoses that need to be checked or flushed. After an operation: rinse the V4A pipes, visually inspect the nozzles, and put everything back in the Eurobox.

Can we buy on account?

Yes, for public authorities, municipalities, volunteer fire departments, and industrial fire brigades. Payment terms after order confirmation. Volume discounts from 3 units on request. Solid-plus-VLITEX bundle on request.

SnakE for underbody cooling

Fighting EV fires

Underbody cooling is the simplest and safest method for efficient firefighting on passenger cars with a lithium-ion battery as the high-voltage battery. Underbody cooling is also recommended in the Tesla Emergency Response Guides.

Underbody cooling avoids additional vehicle damage and poses no risk of unnecessary damage to the battery.

The ladder is continuously cooled by SnakE, and temperatures near the ground are generally not as high.

As an alternative, we offer a foldable aluminum frame that can also be stowed in the Eurobox.

  • ⚙️ Modular

    The modularity of SnakE allows flexible adaptation to different operational situations.

    This makes SnakE versatile for wildfires, electric vehicle fires, and other scenarios. It also facilitates retrofitting, allowing existing vehicles to be used more efficiently.

  • 📦 Compact storage

    SnakE is the smallest and lightest modular fog extinguishing system for cooling high-voltage batteries in vehicles. The entire system can be stowed in a single standard Eurobox.

  • 💡 Intuitive

    Even as a special extinguishing device, SnakE is intuitive to operate and requires minimal training. This allows crews to focus on the essentials and know how to act correctly, even in stressful situations.

How does the modular SnakE system work?

Here is a step-by-step explanation of how to use the SnakE system.

D-hose couplings

Connect modules

The individual nozzle modules are connected with specially designed D-hoses. This ensures an optimal spray pattern at all times and allows SnakE to be easily expanded.

Clamping

Mounting nozzle modules

The nozzle modules can be mounted on a specially dimensioned, foldable aluminum frame or on a sectional ladder. The overall height is so low that the system still fits under most common electric vehicles, even with burst tires.

C-hose couplings

Water supply

The water supply is provided via a C-connection, which is split into two D-outlets after a filter. This ensures a sufficient water supply at all times and protects the nozzles against clogging. The nozzles can therefore finely atomize the water at all times, increasing cooling performance while reducing water consumption! Each nozzle uses only around 20 liters per minute.

Simple expansion

Spray bar

SnakE can be converted into a spray bar with a simple extension kit from us. The same SnakE set can thus equip any pump-and-roll-capable fire apparatus with a wildfire spray bar. Ideal support for vegetation fires, oil trail removal, or street cleaning.

Firefighting in electric vehicles with lithium-ion batteries

Which extinguishing agent should be used for electric vehicles?

The extinguishing agent recommended by the professional associations AGBF and vfdb and by the German Fire Service Association is quite clear: water.

As with firefighting in vehicles with combustion engines, it can also be effective to use extinguishing foam in some cases.

SnakE is suitable for plain water as well as for foam or wetting agents.

What challenges does extinguishing electric vehicles with li-ion batteries pose?

The high-voltage battery in vehicles with alternative drive systems poses an increased risk of electrical accidents. The high-voltage cables are marked orange and must not be cut under any circumstances!

The battery of an electric car is usually installed in the underbody and is therefore difficult to access, so that under normal conditions little cooling water reaches the battery.

The risk with lithium-ion batteries is what is known as thermal runaway, meaning that many battery cells ignite one another through chain reactions. The damage is difficult to localize within the battery.

In addition, vehicles of modern design generally have a higher fire load and burn with greater energy release and smoke development.

How much water should be used when fighting fires involving high-voltage batteries in vehicles with alternative drive systems?

According to the latest recommendations of the German Social Accident Insurance (DGUV), the following approach is recommended for a vehicle accident involving a vehicle with an alternative drive system.

It is advisable to deploy two different nozzles early on: one for conventional car firefighting and one for cooling the lithium-ion battery (LIB).

A small amount of water is usually sufficient for efficient cooling.

It is recommended to gain better access to the underbody of the vehicle, where the high-voltage battery is located, to increase efficiency and keep firewater consumption as low as possible.

What methods are currently available for fighting fires in vehicles with alternative drive systems, e.g. lithium-ion batteries?

  • Wet quarantine/extinguishing container
  • Extinguishing lance
  • Extinguishing spike
  • Fire blankets
  • SnakE underbody cooling

What is the AGBF Bund recommendation for fighting fires in vehicles with electric drive systems?

Following the recommendations of the technical committees for preventive fire and hazard protection and for operations, extinguishing agents, and environmental protection of the German fire services within AGBF Bund, the following procedure was officially recommended in January 2021.

The initial firefighting measures are the same as for a conventional car fire: cooling with water and, if necessary, with extinguishing agent additives such as foam or wetting agents.

It is important to always consult the most up-to-date emergency response guides.

In general, modern vehicles release more smoke and heat.

If the vehicle is an electric vehicle, the high-voltage battery should be examined with a thermal imaging camera.

The efficient extinguishing agent for firefighting remains water.

If, when checking the high-voltage battery in the electric vehicle, a temperature significantly above the ambient temperature is measured, combined with a steady temperature rise, current recommendations call for cooling the housing of the high-voltage battery with water.

Quarantining is explicitly not the fire department's responsibility. In its latest recommendation, the German Social Accident Insurance (DGUV) advises using this method only in absolute exceptional cases, as firewater disposal places a major logistical burden on fire departments. Preventive wet quarantine in particular should be avoided.

The HV battery in the electric vehicle must be cooled and monitored with the thermal imaging camera until the vehicle can be handed over to the operator or a suitable towing company.

Extinguishing success is achieved solely through the cooling effect of the water.
