Why Ferosticker?

Protection Right Where Fire Can Start

F01 sits inside compact electrical and technical enclosures, close to the components it protects. If fire develops, the aerosol is released directly into the enclosed space, suppressing it at the source before it has the chance to spread

Clean, Electronics-Friendly Suppression

Unlike powder extinguishers, FEROSTICKER uses condensed aerosol that does not damage electrical equipment and leaves only minimal residue. That makes F01 especially well suited to fuse boxes, control equipment, inverters and other electronics

Automatic Activation (338°F / 170°C)

F01 needs no sensors, electronics or human intervention. It activates automatically when its activation element reaches approximately 338°F / 170°C or comes into contact with direct flame, providing protection even when nobody is there to notice the problem.

Maintenance-Free for 6 Years

No batteries to replace. No power supply. No annual servicing. Once installed inside the enclosure, F01 remains ready for up to 6 years

Never Underestimate The Stick!

"I was skeptical, because everything claims to be 'set-and-forget.' But after 6 months with Ferosticker in my RV's battery compartment and by the inverter, I actually feel it. That deep-seated worry about a lithium runaway fire? It's gone. Worth every penny for that peace of mind. Highly recommend to any serious RVer."

"After a scare on my last offshore trip, I knew I needed better engine bay protection. Traditional extinguishers are messy and destructive. Plumbed systems are a maintenance headache. Ferosticker is the elegant solution I've been waiting for. It's simple, autonomous, and the clean agent means no damage to my expensive electronics if it ever deploys. This is what modern boating needs."

Rated 5.0 / 5.0 | 'Excellent'

"My classic car's wiring is my biggest concern. I used to check it constantly. The Ferosticker gave me a modern solution for an old problem. It's discreet, easy to install, and knowing it's watching even when I'm not... that's huge. No messy powder, no visible bulk. It truly is invisible insurance."

The Science Behind Your Silent Sentinel

Ferosticker is based on aerosol fire-suppression technology originally developed for extreme environments, including space applications. When the activation element reaches approximately 170°C / 338°F or is exposed to direct flame, it automatically releases highly active potassium radicals that interrupt the chemical combustion process by neutralizing hydrogen, oxygen and hydroxyl radicals, suppressing the developing fire

Stop the fire. Save the fuse box.

A traditional powder extinguisher can leave electrical components covered in difficult-to-clean residue. F01 releases condensed aerosol directly inside the enclosure, suppressing the fire without the same powder mess

Easy To Install

Peel

Pick a clean, flat spot inside the panel or compartment. Wipe it dry, then peel off the backing

Stick

Press it down firmly, above whatever could catch fire. No tools. No wiring.

Check

Leave about 2–3 cm of space around it. The aerosol needs room to spread.

* Ferosticker protects the compartment, not the room. That's the design: it stops the fire inside the enclosure, before it can spread into the room.

** Fire safety is built in layers. Ferosticker is the layer that goes where the others can't: inside the compartments where fires start.
