The foam system is an effective fire suppression solution designed for flammable liquid fires such as oil and chemical fires. It works by mixing foam concentrate with water using a proportioning device, generating foam that blankets the fire surface to isolate oxygen and suppress heat, effectively stopping the fire. Components include foam bladder tanks, proportioners, foam generators, and nozzles or monitors. It is ideal for petrochemical plants, fuel depots, aircraft hangars, marine docks, and other high-risk environments.
