Designing a foam fire suppression system requires special expertise – expertise that Wormald has developed over many years.
Wormald systems are reliable and suppresses the fire quickly, giving you confidence that fire risks are reduced to acceptable levels. For foam systems, foam must be delivered to the fire efficiently and in a controlled and directed manner. Our fire protection design engineers have experience over a vast range of installations and are able to call on the knowledge of colleagues from around the world in the Tyco group. Our designers will analyse your facility, the fire risk and consider likely scenarios. They will design a system configuration to effectively combat fire, help you consider the options and decide upon the most suitable solution.
Low Expansion Foam
Low Expansion foam offers a 5:1 expansion rate, making it the foam system of choice in Australia to protect large and hazardous facilities, including; petro-chemical tank farms, loading docks, processing areas and refineries and liquefied natural gas storage.
Organisations storing or handling flammable and combustible liquids will usually need to comply with Australian Standards AS1940 ‘The Storage and Handling of Flammable and Combustible Liquids’ and Wormald can provide the design expertise and system components to help any facility comply with this Standard.
High Expansion Foam
With an expansion rate of 500:1, High Expansion foam systems are more suitable to protect less common three-dimensional hazardous facilities including; warehouses, conveyors, aircraft hangars and tunnels. As such, High Expansion foam is measured by volume output rather than application rate, as is typical of low expansion foams.
With both low and high expansion foam systems, once a facility has been evaluated either an ‘Aspirating’ or ‘Non-Aspirating’ discharge device’ will be recommended, based on the facilities requirements.
For maximum effectiveness it is critical the expansion ratio, discharge device and foam concentrate be correct. With our knowledge and expertise, Wormald can recommend the most appropriate devices for your situation.
