Bladder tank

for fire extinguishersstorageindustrial

Overview
Bladder tanks provide combined foam concentrate storage and balanced-pressure proportioning for fixed foam systems. On activation, pressurized water propels concentrate from the bladder through the proportioner to discharge foam into the protected hazard area. These pressure-rated systems are available in multiple orientations and configurations for integration with firewater piping.

Features

• Operates using only a pressurized water supply; no external power required.
• Standard grooved coupling connections for straightforward integration with firewater piping.
• Available in horizontal, vertical and pre-piped models.
• Configurable options: trim piping material, corrosion-resistant paint, color, sight gauges, thermal pressure relief valves.
• Open-leg design provides access to tank bottom; primary shutoff valve allows easy installation or replacement of sight gauge.
• Reversible water inlet for piping to either side of vertical tanks.

Benefits

• Configurable: Tank capacities from 50 to 3000 gallons (190–11,350 L) with horizontal or vertical orientations and multiple piping layouts for tailored installation and fast delivery.
• Reliable performance: UL-listed bladder tank systems are performance-tested with corresponding foam concentrates.
