F-500 EA® Diamond Doser® Fire Suppression System
F-500 EA® Diamond Doser® Fire Suppression System is a water-driven volumetric proportioner that injects encapsulator concentrate into fire streams without external power, delivering reliable suppression for lithium-ion battery and industrial fires.
Key Features:
✔️ Water-driven volumetric proportioner — no electrical power required
✔️ Available in 12 flow capacities from 50–10,000 L/min (13–2,645 GPM)
✔️ DN40–DN250 inlet/outlet connections for varied system integrations
✔️ Mobile units draw concentrate directly from pails, drums, or totes
✔️ Automatic air-relief valve accelerates priming during deployment
✔️ Fixed installation compatible with deluge and sprinkler systems
✔️ Maintains consistent F-500 EA® dosing across variable flow rates
✔️ Optional dosing return valve supports NFPA testing without agent waste
✔️ Fluorine-free encapsulator concentrate with biodegradable profile
F-500 EA® Diamond Doser® Fire Suppression System
The F-500 EA® Diamond Doser® Fire Suppression System operates as a water-driven volumetric proportioner injecting encapsulator concentrate into water streams without electrical power requirements. Available in twelve flow capacities from 50-10,000 liters per minute (13-2,645 GPM), inlet/outlet connections range from DN 40 to DN 250 thread sizes. Mobile configurations feature suction tubes inserting directly into concentrate containers from pails to totes, with automatic air relief valves accelerating priming during deployment. Fixed installations integrate with deluge and sprinkler systems, automatically adjusting concentrate dosing as additional discharge heads activate during lithium-ion battery fires.
Applus+ internationally approves the system under ETI 23/32306438 certification. FILK testing demonstrated successful extinguishment of a Hyundai Kona Electric 64kWh battery fire in 8 minutes 30 seconds. The proportioner maintains consistent F-500 EA® concentration across varying flow rates and multiple simultaneous nozzle operations at different elevations. Optional dosing return valves enable NFPA-mandated testing without generating agent solution, reducing annual compliance costs. The fluorine-free concentrate biodegrades naturally, eliminating hazardous waste disposal fees associated with PFAS-containing foams.
Fire departments deploy the F-500 EA® Diamond Doser® Fire Suppression System on airport tarmacs for electric aircraft emergencies where three-dimensional fuel fires exceed foam suppression capabilities. Battery energy storage facilities install fixed systems protecting utility-scale lithium-ion arrays where thermal runaway propagation demands immediate encapsulator application. Electric vehicle charging station operators integrate proportioners with existing sprinkler infrastructure, addressing parking garage fires without complete system replacement. Industrial recycling facilities processing lithium-ion batteries use mobile units for rapid response to spontaneous combustion events during material sorting operations.
Tactical Supply Pakistan distributes water-driven proportioning systems for lithium-ion battery fire suppression across industrial and municipal fire protection applications. The company provides hydraulic calculations for system sizing and concentrate consumption estimates based on facility hazard assessments.
How does water-driven proportioning maintain accuracy without electronic controls during dynamic firefighting conditions?
The venturi effect creates pressure differential proportional to water flow velocity, drawing concentrate at consistent ratios regardless of electrical availability, enabling reliable F-500 EA® injection even when nozzles open and close rapidly during pulsed suppression techniques on lithium-ion battery fires.
