Vehicle Fire Suppression Systems: Dry Chemical, Wet Agent or Dual Agent?

Every restaurant, from pizza places to fine dining, has a fire suppression system installed in the kitchen. Sure, these suppression systems are required by law, but they’re also smart investments to protect expensive equipment. That’s why vehicle fire suppression systems are vital safety features for everything from heavy machinery for mining to buses for public transit. Unlike a simple fire extinguisher, suppression systems can detect and suppress fires before operators are harmed or equipment is damaged.


What Vehicle Fire Suppression System Do I Need?

Hawkeye Fire & Safety partners with multiple fire suppression system manufactures – Afex, Ansul and Amerex – so that we can design the right suppression system for each of your vehicles. There are three different types of suppression systems: dry chemical, wet agent and dry agent. Depending on the industry and environment, each of these suppression systems can effective protect vehicles and heavy equipment.


Dry Chemical

Dry Chemical Vehicle Fire Suppression Systems are the standard for heavy equipment because they provide the efficient protection by quickly starving the fire of oxygen, although it is necessary for the operator to remove or wet down any combustibles around the fire to prevent it from reigniting. Dry chemical suppression systems are effective against debris, fuel and electrical fires.


Wet Agent

Wet Agent Vehicle Fire Suppression Systems (also known as liquid agent suppression systems) are great for protection against debris and fuel fires because they not only suppress the fire with a layer of foam but also cool the hot surfaces to prevent them from igniting. This one-two punch of fire suppression and cooling makes wet agent suppression systems one of the most popular suppression systems.


Dual Agent

Dual Agent Vehicle Fire Suppression Systems include a dry chemical tank and a wet agent tank that work together to suppress the fire and prevent damage. First, the dry powder starves the fire, and then the liquid cools the components. It’s an extremely effective combination, especially as machines continue to become more advanced and powerful, creating additional fire risks throughout the engine compartment.


Inspection and Maintenance for Vehicle Fire Suppression Systems

After Hawkeye Fire & Safety designs and installs your suppression system, we continue to work with you to protect your vehicles and heavy equipment through semi-annual inspections of the system. These inspections will ensure compliance with National Fire Protection Association (NFPA) requirements. We also provide direct access to ongoing technical assistance.

If you need a vehicle fire suppression system designed and installed, or if you need to make sure your current suppression system complies with NFPA code, contact Hawkeye Fire & Safety in Cedar Rapids and Iowa City.
