Application Scope
Large-scale Petrochemical Industry: High-risk sites such as refineries and chemical parks.
Large Logistics Warehouses: Ensures the safety of logistics materials and prevents fires.
Crude Oil Terminals: Effectively addresses potential fire risks and ensures transportation safety.
Airports: Provides safety guarantees for aircraft fires.
Offshore Platforms: Ensures operational capability in special environments and guarantees the safety of offshore operations.
Substations and Loading/Unloading Areas: Ensures the protection of high-risk equipment and reduces losses.
Working Principle
The balanced foam proportioning device relies on the pressure difference between water flow and foam concentrate. Through the internal mixer, the two are effectively mixed in a set ratio. When the system is activated, the water flow draws in the foam concentrate to form a mixture, which is then sprayed onto the fire source through nozzles. The system can automatically adjust the foam ratio to ensure optimal fire-extinguishing effectiveness.
