The Angus Fire bladder tank is a steel pressure vessel fitted with an internal bladder that stores foam concentrate. It is an integral component of the bladder tank proportioning system.
During operation, water supplied to the bladder tank displaces the foam concentrate and collapses the bladder until the concentrate is depleted. The bladder tank discharges foam concentrate at approximately the same pressure as the water supplied at the water inlet connection to the tank. As the bladder tank is pressurised, the bladder cannot be refilled during operation.

Angus Fire’s LNG Fixed Turbex Systems are used for bund fire protection.They meet the extremely demanding performance requirements for this high-risk application and can be positioned on a skid for easy mounting on a bund.
High expansion foam systems represent the most effective fire protection for such specialised and severe cryogenic risks as LNG (Liquefied Natural Gas) and LPG (Liquefied Petroleum Gases).

Angus Fire’s Foam/Water, open, air aspirating, nozzles designed for use as part of an engineered fire protection system.
Each sprinkler is designed for mounting in the pendant position and produces a solid cone discharge, with very similar spray patterns for both foam and water.

Angus Fire Fixed In-line Inductors are designed primarily for use in fixed installations and provide a simple and reliable method of proportioning foam concentrate in constant flow/contestant pressure applications.

Angus Balance Valves provide a reliable and cost-effective way of ensuring Balanced Pressure Foam Proportioners perform accurately over a range of flows and pressures by balancing the pressure of the foam concentrate entering the proportioner with the pressure of the water at the inlet.

Angus Balanced Pressure Foam Proportioners (BPPs) are designed for use in fire protection fixed systems to introduce foam concentrate at a predetermined rate into the fire-water supply, over a varying range of foam solution demands.

The Angus Fire Top Pourer Set (TPS) Mk5 is designed for use in foam systems for the protection of fixed roof flammable liquid storage tanks and combines foam generation, vapour sealing and foam pouring in a robust, low-maintenance design. The TPS Mk5 represents over 35 years of product development and operating experience. Modern materials such as graphite and stainless steel are employed to ensure each unit performs to the precise pressure and flow standards laid down by Underwriters Laboratories (UL) and NFPA.

The Angus Fire Top Pourer Set (TPS) Mk4 is designed for use in foam systems for the protection of fixed roof flammable liquid storage tanks with Nitrogen inerted blankets or where tank internal pressures may reach 0.35 bar (5 psi). The Mk4 combines foam generation, vapour sealing and foam pouring in a robust, low-maintenance design and represents over 35 years of product development and operating experience.

For the protection of floating roof tanks with geodesic roofs
Angus Fire’s Rimseal Foam Equipment is used for the protection of vertical Open Top Floating Roof (OTFR) storage tanks in the event of a fire.
Some OTFR tanks are fitted with Geodesic lightweight roofs to maximise vapour recovery and to keep the weather out. These lightweight roofs are often of a construction that will not support the weight of a conventional fixed foam pourer. Provided the tank roofs are fitted with rimseal foam dams, there is the option of fitting the Angus Geodesic Rimseal Pourer. These units comprise of a Rimseal Foam Generator (RFG) that produces expanded foam when supplied with foam solution and a Geodesic low level Pourer that delivers the foam gently into the rimseal area. 

Full Surface Pourer – 150 & 100
The Angus Full Surface Pourer provides additional foam application in case a full surface fire develops.
Floating roof storage tanks are inherently very safe, however, if the roof sinks, the full surface area of the tank contents are exposed to atmosphere and fire will engulf the whole tank surface.
The Full Surface Pourer is specifically designed to provide these higher flow rates whilst generating good quality expanded foam when used with a high performance Angus foam concentrate – including new generation Fluorine free foam Respondol.

The Angus Rim Seal unit offer fire protection for open top floating roof tanks at tank farms. It’s comprised of two elements:
The Rim Seal Foam Pourer (RFP) that delivers the foam gently into the rim seal area
The Rim Seal Foam Generator (RFG) that produces expanded foam when supplied with foam solution

Automatic Foam Delivery Modules
The Angus Floatafoam System comprises a number of fully automatic foam delivery modules designed to detect and extinguish floating roof tank rim seal fires in their infancy.

Angus Rimseal Foam Equipment is used for protecting vertical open top floating roof (OTFR) storage tanks form the risk of fire.

• RFP50F – 2” ANSI Flanged inlet (Does not require separate foam generator)
• RFP80F – 3” ANSI Flanged inlet (Does not require separate foam generator)

Angus Medium Expansion (MEX) Bund Pourers are designed for fire protection systems and vapour suppression on bunded or diked areas surrounding flammable liquid or toxic chemical storage tanks.
The Angus range comprises three lightweight, compact and robust units. Foam solution flows range from 465- 1970 litres per minute at inlet pressures of 1.5 to 2.5 bar g. Operation at such low pressure minimises pumping capacities and water requirements, ensuring a cost effective system.

K40 MK2 & K20 MK2 Foam/ Water Sprinklers

Each sprinkler is designed for mounting in the pendant position and produces a solid cone discharge, with very similar spray patterns for both foam and water.

Angus Fire Base Injection Generators (HBPGs) (also known as sub-surface foam injection) are sub-surface foam injection systems suitable for use on vertical fixed roof storage tanks containing flammable or combustible hydrocarbons (as detailed in NFPA11 and EN13525 part2).
It is not recommended to use Base Injection for Polar Solvent fuels.

Angus HI-COMBAT Turbex High Expansion Foam generators are suited to a wide range of applications. The unit is also capable of rapid smoke extraction (SX), positive pressure ventilation and removal of foam once the fire is extinguished.
Each unit is designed to produce large capacities of high expansion foam, up to 200 cubic metres (7,000 cu.ft) per minute for fast and effective flooding of large and inaccessible spaces with minimal water consumption and subsequently minimal water damage.

The Angus Helijector is designed to provide a fixed percentage foam concentrate injection (1% or 3%) into a monitor or similar foam system with a constant foam solution demand.
