Liquid chemical fire suppression systems provide exceptional cooling abilities to suppress Class A (debris) and Class B (fuel) fires. The liquid agent works by cooling hot surfaces, separating fuel hydrocarbon molecules to prevent fire reignition and forming a layer of foam to suffocate flames. Liquid systems are especially designed to protect high risk vehicle components, such as turbochargers, exhaust components, and Tier 4 aftertreatment components.

Combining the Benefits of Liquid & Dry Chemical Agents

As equipment manufacturers design machines that are more powerful and productive, the risk of more severe fires due to increased heat throughout the engine compartment and hydraulic systems grows. A dual agent fire suppression system combines the benefits of dry chemical with liquid agent to address these risks.

Liberty Frac Pumps with AFEX Fire Suppression Systems for the Digital Oilfield

Oil, Gas and Energy

Fracking vehicles operating side by side with little room between them create an environment where fire can easily spread. The tight space allows for little to no access to fire fighting measures. Equipment fire protection systems attack the source of the flames before they have a chance to spread. Safeguard your investments today.
