Bladder Tanks

Bladder Tanks are a component of a balanced pressure proportioning system that includes a pressure-rated tank with an internal elastomeric bladder for foam concentrate storage. Upon system actuation, incoming water applies pressure to the concentrate in the bladder, which supplies pressurized concentrate to the proportioning device. The device meters the foam concentrate into the fire water line, creating foam solution. The solution is then piped to the discharge devices protecting the hazard area.

Bladder tanks have numerous applications, including truck loading racks, aircraft hangers, dip tanks, pump rooms and helipads. Because the tanks require no external power supply other than a pressurized water source, they are more economical compared to pump systems (for systems under 2,000 gallons). And bladder tanks, because of their simple design, require very little maintenance.

Bladder tanks are available in horizontal, vertical and pre-piped models.

Features

Horizontal and Vertical Bladder Tanks

Bladder tanks are available in both vertical and horizontal tank models and a variety of nominal capacities. Both models feature perforated center tubes that allow improved agent discharge.

Features include:

Water pressurized bladder construction, alleviating the requirement for foam pumps or other energy sources
Valves pinned in the normal operative positions and supplied with nameplates identifying their functions and operating instructions
Bladder tanks supplied with corrosion-resistant piping
Exterior tank surfaces finished in red standard system paint or coated with an epoxy “CR” red finish for use in marine or corrosive environments
Tanks with a high build epoxy coated interior for use with both fresh and salt water
Built to ASME code

Pre-piped Bladder Tank

The Pre-piped Bladder Tank is a complete balanced pressure proportioning system. The tank offers the foam system designer fixed dimensions inclusive of the proportioner/ratio controller. In addition, the installer has the advantage of a pre-fabricated foam system, eliminating loose components and simplifying the installation. Its operation requires no external power other than a pressurized water system. The bladder tank may be used with any ANSUL foam agent and with any suitable discharge device.

Features include:

Water pressurized bladder construction, alleviating the requirement for foam pumps or other energy sources
Valves pinned in the normal operative positions and supplied with nameplates identifying their functions and operating instructions
Proportioner and piping attached to side of tank
Complete bill of materials with fixed dimensions
Corrosion-resistant piping
Exterior tank surfaces finished with a red “CR” epoxy finish for use in marine or corrosive environments
Tanks with a high build epoxy coated interior for use with both fresh and salt water
