The foam seal ring device is designed to discharge fully breathed foam directly into the annular seal area of open roof floating roof storage tanks for fire or vapor containment. Fully breathed foam provides the most effective performance for all types of foam concentrates.

Seal ring foam machine is designed using UL Listed CGFLR-30 or CGFLR-90 foams. The design of the ring porr protects the wind and allows the breathed foam to slowly drain into the protected area of the floating roof tank. Gentle application minimizes sloshing and stirring and increases the performance of the foam blanket. This design allows for uniform and consistent flow of foam.

Both CGFLR-30-FP and CGFLR-90-FP foam sealing rings are classified as Type II discharge devices in accordance with NFPA 11, "Standard for Low, Medium, and High Expansion Foam."
