What Is it?

A cost-effective, environmentally friendly, automatic fire suppression device, that extinguishes fire from its inception. It’s a small, simple plastic tube containing extinguishing agent FM-200®.

The system is fully automatic and responds to increasing temperatures. At temperatures of 158°F (Standard) or 194°F (Heavy Duty) and or contact with direct flame, the tube ruptures, releasing the non-toxic agent and thus extinguishing the protected area.

What is FM-200

FM-200 is also known as Heptafluoropropane, HFC-227 or HFC-227ea (ISO name), as well as apaflurane (INN)

FM-200™ is the world’s most widely selected clean agent for use in new applications and as a Halon 1301 replacement. It is suitable for use in a wide range of fire extinguishing applications, including total flooding, streaming, and inerting applications. FM-200™ (HFC227ea, CF3CHFCF3) is a safe, clean, and electrically non-conductive agent that protects people, high value assets, and the continuity of business operations.

FM-200™ has been validated by independent agencies and received component approval from Underwriters Laboratories (UL) and Factory Mutual Research Corporation (FM). It is listed as an acceptable agent for the replacement of Halon 1301 and new applications in the United States Environmental Protection Agency’s (EPA’s) Significant New Alternative Policy (SNAP) program in both total flooding and streaming systems. FM-200™ has a zero ozone depletion potential (ODP) and is the environmentally preferred alternative to Halon 1301. FM-200™ is included in the National Fire Protection Association (NFPA) 2001 Clean Agent Standard and the International Standards Organization (ISO) 14520 Clean Agent Standard.

Is it safe/ECO Friendly?

The PROTENG® fire suppression device contains gas that’s electrically non-conductive and also non-corrosive so there will be no damage to electronics or delicate mechanical devices.

If contact with skin or eyes, immediately flush with plenty of water for at least 15 minutes. Take off contaminated clothing immediately and wash before re-use. If inhaled, remove from exposure to fresh air and lie down. Consult a physician.

Environmentally friendly?  Yes, it’s non-toxic and environmentally friendly. Our system uses a clean agent known as FM-200, which is a natural gas that’s harmless to the environment.

What is different about a Fire Extinguisher

Traditional fire extinguishers and fire suppression systems are typically large, heavy or bulky. Our device is a small plastic tube that’s simple, lightweight, easy to install, and requires no maintenance.

Traditional fire extinguishers use a foam or powder that leave residue behind which needs to be cleaned up, can cause damage to valuable assets. The vast majority also contain chemicals that are dangerous.

Beyond that, traditional fire extinguishers are typically applied after a fire is ablaze and out of hand. PROTENG® fire suppression device uses a natural gas that stops fire from the moment it starts, without causing further damage to your property.

Other Suppression units have sensors to focus on the ideal hot spots where our tubes cover around the engine compartment and can deploy from any angle.
