Bladder Tank Foam Proportioners

Fire safety systems have undergone significant advancements over the years, resulting in innovative solutions that are more reliable and efficient. One such innovative solution in the field of fire protection systems is the Bladder Tank Foam Proportioner.

This system plays a pivotal role in accurately mixing foam concentrate with water to produce a foam solution, which is then used to extinguish fires.

What is a Bladder Tank Foam Proportioner?

A Bladder Tank Foam Proportioner is a component of a balanced pressure proportioning system that includes a pressure-rated tank with an internal elastomeric bladder. The bladder is used for storing foam concentrate. Upon system actuation, incoming water applies pressure to the bladder, which then supplies pressurized foam concentrate to the proportioning device called Ratio Controller. The device meters the foam concentrate into the fire water line, creating a foam solution which is then piped to the discharge devices protecting the hazard area.

What is a Bladder Tank Foam Proportioner?

The foam concentrates that are compatible with Bladder Tank Foam Proportioners include:

  • AFFF (Aqueous Film Forming Foam)
  • AR-AFFF (Alcohol Resistant - Aqueous Film Forming Foam)
  • SFFF (Synthetic Fluorine Free Foam)

Applications of Bladder Tank Foam Proportioners

Foam bladder tanks are commonly used in fire protection systems, particularly in facilities where there is a risk of flammable liquid fires or where large-scale fire suppression is necessary. These systems find extensive use in various applications such as:

  • Truck loading racks
  • Aircraft hangers
  • Refineries
  • Tank farms
  • Pump rooms
  • DG Set rooms
  • Ports & Terminals
  • Chemical Warehouses

Construction of Bladder Tank Foam Proportioners

Bladder Tank Foam Proportioners come in a variety of constructions to meet different requirements. They can be vertical or horizontal units. Carbon Steel or Stainless Steel is usually used in their construction, ensuring durability and resistance to harsh environments.

Features of Bladder Tank Foam Proportioners

Bladder Tank Foam Proportioners are designed keeping in mind the ease of installation, usability, and system efficiency. Here are some of the key features:

  • Open Leg Design
  • This design provides easy access to the bottom of the tank, facilitating maintenance and inspection processes.
  • Standard Flange or Grooved Connections
  • This feature ensures easy integration into firewater piping, thereby making the installation process straightforward and efficient.
  • Valve Nameplates
  • These nameplates eliminate confusion about which valve is which or what position it was left in. This can be crucial during emergency situations when quick and correct decisions are needed.
  • Pressure Relief Valves
  • Each Bladder Tank is provided with a safety device installed on the tank shell to prevent over-pressurization of the bladder. It automatically opens to release excess pressure if the pressure inside the tank exceeds a certain threshold, protecting the tank from damage.

Advantages of Using Bladder Tank Foam Proportioners

Bladder Tank Foam Proportioners offer numerous advantages over conventional foam proportioning systems.

  • Economical Because the tanks require no external power supply other than a pressurized water source, they are more economical compared to pump systems in most of the cases.
  • Low Maintenance Owing to their simple design, bladder tanks require very little maintenance, thus reducing the overall cost of ownership.
  • Reliability Bladder Tank Foam Proportioners are known for their reliability. They offer a simple and efficient method of foam proportioning, making them an ideal choice for fire protection systems.

Reference Standards:

NFPA 11 provides requirements for the design, installation, operation, testing, and maintenance of foam systems used in various applications, including:

  • Low-expansion foam systems
  • Medium-expansion foam systems
  • High-expansion foam systems

NFPA Standard covers aspects such as the selection of foam concentrate, foam proportioning equipment, foam storage, foam application devices (such as foam chambers, foam makers, and foam monitors), system layout, testing procedures, and maintenance requirements. Additionally, other NFPA standards may apply depending on the specific application or industry. For example:

NFPA 30: Flammable and Combustible Liquids Code includes requirements for the storage, handling, and use of flammable and combustible liquids, which may necessitate the use of foam systems for fire protection.

NFPA 409: Standard on Aircraft Hangars covers fire protection requirements for aircraft hangars, including the use of foam systems for fire suppression.

UL 162: Standard published by Underwriters Laboratories (UL) titled “Standard for Safety for Foam Equipment and Liquid Concentrates”. This standard covers the safety requirements for foam equipment and liquid concentrates used in fire protection systems, including foam bladder tanks.

FM Approval Standard 5130: Standard specifies the requirements for the design, construction, installation, and testing of low expansion foam systems intended for use in fire protection applications. These systems are typically employed in facilities where there is a risk of flammable liquid fires or where large-scale fire suppression is necessary.
