  • FIRE-X-TROL®
    Wet Pipe Sprinkler System ASME Expansion Chamber

    • UL Listed for use with Fire Protection Anti-Freeze systems per NFPA 13.
    • Accommodates the expanded volume of WATER in your system.
    • Designed, constructed and tested per ASME section VIII, Division 1 Standards.

    The Fire-X-Trol® expansion chamber with pre-charged nitrogen or dry air pneumatic cushion reliably protects your system from pressure increases that result from antifreeze temperature change. Since these systems are closed-loop systems, the expanded fluid needs to be accommodated with a pre-pressurized expansion tank.

    As the temperature rises, the Fire-X-Trol® provides the additional space in the system to accommodate the expanded volume of solution. The pneumatic cushion is compressed as the system pressure increases creating the space for the increased volume of antifreeze solution. The nitrogen volume in the chamber will be great enough to keep the system pressure below the pressure limitations of the system components. Properly sized, the expansion chamber will maintain maximum system pressures within the working pressure limitations of the system equipment. Your system is safely protected!
