Foam Suppression Systems

For fixed foam suppression systems, the foam must be delivered to the fire efficiently and in a controlled and directed manner. DIS Fire Systems have vast experience over a range of installations and are able to draw on the knowledge of Foam Manufacturers such as Ansul and Chemguard to assist if required.

DIS Fire Systems will analyse your facility, the fire risk and consider likely scenarios. We can then design a system configuration to effectively combat fire, help you consider the options and decide upon the most suitable solution for your needs.

Low Expansion foam offers a 5:1 expansion rate, making it the foam system of choice in 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 DIS Fire Systems 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.

Discharge Devices 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.

  • Aspirating discharge devices - produces a more viscous foam – great for reducing burn back and keeping the foam contained;
  • Non-aspirating discharge devices - are best used where the foam is needed to spread over a large area.

For maximum effectiveness it is critical the expansion ratio, discharge device and foam concentrate be correct. With DIS Fire Systems knowledge and expertise, we can recommend the most appropriate system solution for your needs.
