Compact Foam 3S

Compact Foam 3S is a reliable fire extinguishing system that is easy to operate and suppresses fires thoroughly. It brings together a high level of rationality and safety. Compact Foam 3S is the ultimate package engineered for the future.

Easy and safe to operate
In the event of a fire breaking out, the supervisor can choose which island to release the foam extinguishing agent using the system activation panel, so that the agent is released only at the desired location.
Up to 12 lines to meet the needs of large gas stations
With up to 12 lines of selector valves, the system can accommodate even large gas stations.
Thoroughly suppressing a fire from its source
The extinguishing agent is released from the sides of the islands where vehicles are stopped to ensure effective fire extinguishing at close quarters.
Thorough fire suppression with mechanical foam extinguishing agent
Excellent sealing properties of the extinguishing agent put out the fire rapidly and reliably through smothering and cooling actions.
