As technology advances, equipment manufacturers are designing  machines that are more powerful and productive while also reducing emissions. The downside to these advancements is a growing risk of more severe fires due to increased heat throughout the engine compartment and hydraulic systems.

Dual agent systems join the best features of our dry and liquid chemical vehicle fire suppression systems for the ultimate protection against fire. Our dry chemical system provides fast fire knockdown and total-flooding of enclosed compartments, while the liquid chemical system targets hot surfaces for fast cooling and protection against fire reignition. Dual agent systems are so effective that the National Fire Protection Agency (NFPA) require them for large hydraulic shovels.


Dual Agent System Features

  • Total-flooding, especially in well enclosed areas
  • Unparalleled fire knockdown speed
  • Effective at cooling hot surfaces in open areas
  • Fight against fire reignition
  • Small footprint
  • More economical than liquid chemical systems alone
  • Penetrates debris and suppresses pooled fuel fires
  • Manual and automatic system discharge
  • Class A, B and C fire protection
  • Suitable for temperatures as low as -40°F (-40°C)
  • Third-party tested and approved by FM HDME, Activfire, AS 5062, and CE
