Fixed Foam Equipment

Fixed foam equipment is permanently installed firefighting equipment designed to protect high risk areas by automatically or manually delivering foam to a specific hazard zone.

Delta Fire fixed foam systems include equipment such as foam pourers, foam generators, in line inductors, and balanced pressure proportioners. These components are installed at fixed locations like tank farms, bund areas, helidecks, and industrial facilities.

Unlike portable foam equipment, fixed systems provide continuous, targeted protection for known risks and are designed to deliver foam directly to the hazard area when required.

Fixed foam equipment is typically installed in high risk areas where flammable liquids or fuel hazards are present and continuous protection is required.

Delta Fire fixed foam systems are commonly used in locations such as storage tank farms, bunded areas, helidecks, loading racks, fuel storage facilities, and processing plants. They are also found in marine and offshore installations where fuel handling and transfer operations take place.

These systems are positioned to provide direct, targeted foam application to the protected hazard area in the event of a fire.

A rimseal pourer is designed specifically to protect the seal area between a floating roof and the tank wall on storage tanks. It delivers foam gently into the rim seal to suppress vapours and prevent fire spread around the tank perimeter.

A bund pourer is used to protect bunded areas around tanks or equipment. It applies foam over a wider ground level area to control spills and fires contained within the bund.

A foam top pourer is installed to discharge foam directly onto the surface of a liquid in a storage tank. It provides full surface coverage to extinguish fires by forming a blanket over the fuel.

Delta Fire supplies all three types of pourers as part of fixed foam protection systems for industrial, petrochemical, and storage applications.

Foam is introduced into a fixed foam system by mixing foam concentrate with water at a controlled ratio before it is delivered to the discharge devices.

Delta Fire fixed foam systems typically use equipment such as inline inductors or balanced pressure proportioners to accurately meter the foam concentrate into the water stream. The resulting foam solution is then piped through the system to devices such as pourers or foam generators, where it is expanded and applied to the hazard area.

This process ensures the correct foam strength and consistent performance for effective fire suppression.

The correct foam solution application rate is determined by assessing the type of fuel, the size of the hazard area, and the relevant fire protection standards for that application.

In practice, designers calculate the total area that requires protection and apply the minimum recommended application rate for that fuel type, ensuring enough foam solution is delivered to achieve extinguishment and prevent re ignition. Hydrocarbon fuels typically require lower application rates than polar solvents, which need higher rates or specialist foam types.

Delta Fire fixed foam systems are designed and specified in line with these requirements, using equipment such as proportioners, pourers, and foam generators to ensure the correct flow and coverage are achieved.

Environmental conditions, wind, and discharge method are also considered to ensure the foam remains effective once applied.

Fixed foam equipment should be inspected regularly to ensure it remains fully operational and ready for use.

Delta Fire fixed foam systems are typically subject to routine visual inspections, often monthly or in line with site safety procedures, to check for corrosion, blockages, damage, and correct system condition.

More detailed functional testing, including system operation and foam discharge performance, is usually carried out annually or according to relevant site standards and regulations.

Any defects, leaks, or performance issues should be addressed immediately through servicing or repair to maintain reliability and compliance.
