Production introduction
Tailored for sites where power reliability is critical, the foinbo® Engine Driven Fire Foam Mixing Unit brings steady foam mixing performance to industrial and high-risk fire protection systems. Built with a diesel engine as its primary backup power source, it operates fully independent of grid electricity, making it ideal for remote facilities, off-grid sites, and areas prone to frequent power outages. Using balanced pressure proportioning, it blends foam concentrate and water at a precise 3–3.9% ratio, adjusting automatically to water flow and pressure shifts to maintain consistency. With a working pressure of 1.2 MPa and flow rates ranging from 8 to 250 L/S across different models, it supports foam delivery to generators, guns, and monitors for fast, effective fire suppression.
Each unit of Engine Driven Fire Foam Mixing Unit is built for resilience and low-effort upkeep. The diesel engine drive eliminates reliance on external power, ensuring continuous operation even when the main grid goes down. The balanced pressure valve removes the need for manual fine-tuning, reducing setup time and minimizing the risk of operational errors. The unit's heavy-duty build stands up to harsh conditions-corrosive air, extreme temperatures, and constant use-without compromising performance. Its compact footprint and standard DN100–DN300 flanged connections make installation straightforward in both new and existing fire networks.

Application Scenarios Detail
-
Remote Oil & Gas Facilities: For drilling rigs, pipeline stations, and isolated well sites, the engine-driven unit provides self-contained foam mixing without grid power, protecting against oil and gas fires in off-grid locations.
-
Port & Terminal Fuel Storage: At coastal ports and fuel depots, it delivers reliable foam-water mixtures to suppress ship and storage tank fires, even when shore power is unavailable during emergencies.
-
Mining & Industrial Camp Sites: In remote mining operations and temporary industrial camps, the unit runs independently of local power grids, supporting foam fire protection for equipment, fuel storage, and worker facilities.
