  1. Wet Pipe Sprinkler System Expansion Chamber Sales Presentation October 2004

  2. FIRE-X-TROLFeatures & Benefits • Absorbs expanded antifreeze solution • Diaphragm expansion chamber (4X cycles of a bladder style tank) • Protects system and components from thermal expansion • UL listed • for use with fire protection antifreeze systems per NFPA 13 • ASME • Designed, constructed, and tested per ASME Section VIII, Division 1 Standards • Available code and non-code

  3. FIRE-X-TROLFeatures & Benefits • Pre-charge is separated from system fluid • 5X safety factor by design • Protects system and components from thermal expansion • Helps prevent system hydraulic lock-up • Required when backflow prevention device is used (most local regulations) • Seismic restraints available (vertical models) • Antifreeze compatible • (Glycerine and Propylene Glycol) • Broad range of sizes • 4 to 90 gallons (15 – 341 ltr.)

  4. FIRE-X-TROLHow does the Fire-X-Trol work? • It is installed between the backflow preventer and fill cup • It’s sealed-in dry air/nitrogen pre-charge chamber prevents antifreeze solution from entering it until the system pressure exceeds the pre-charge pressure. • As the antifreeze solution temperature rises, expanded system fluid enters the Fire-X-Trol non-corrosive reservoir. • The Fire-X-Trol absorbs the pressure increase, keeping system pressure below maximum system rating. • As the fluid temperature decreases, pressure in the dry air /nitrogen chamber forces system fluid out of the expansion chamber and back into the system.

  5. FIRE-X-TROL • Materials of Construction • All steel body construction with stainless steel system connection • Polypropylene Liner Material • Diaphragm Material: UL certified high-performance elastomeric compound • Coating: FPT Red • Maximum Operating Conditions • Maximum Working Pressure: 175 psig (12 bar) • Operating Temperature: -20 F (-29 C) to 200 F (93 C) • Factory pre-charge: 25 psig (1.7 bar)

  10. Fire-X-Trol used with Backflow Preventer • NFPA 13 requirement As stated in NFPA 13, 7.5.3.3: “Where the connection between the antifreeze solution and the wet pipe incorporates a backflow prevention device, a listed expansion chamber of appropriate size and pre-charged air pressure shall be provided to compensate for thermal expansion of the antifreeze solution…”

  11. FIRE-X-TROL Installation • Visually inspect FIRE-X-TROL for any damage. • Hydraulic system pressure must be at zero. • Attach nitrogen or dry air supply to expansion chamber charging valve • Dry air: -50 F / -46 C dew point or lower • Pre-charge to 2 psig (0.14 bar) below system static pressure at tank location. • Never pre-charge below 25% of the system maximum rated pressure. • Remove charging hose. Carefully test charging valve for leakage. • Replace plastic cap.

  12. Antifreeze Solution Table

  13. Sizing Chart Note1: AMTROL recommends installing a pressure reducing valve before the backflow preventer. Note 2: The system pressure is too close to the maximum working pressure. NFPA 13 recommends installing a pressure reducing valve before the backflow preventer.

  15. FIRE-X-TROL Warranty and Lead-time • Warranty • Limited (1) year warranty • Lead-time • 10 working days • Safety stock inventory for quicker delivery if required

  16. FIRE-X-TROL FAQ’s Q: What division does Fire suppression systems fall under? A: Division 13. Q: What does NFPA stand for? A: National Fire Protection Agency Q: What fluids can be used with the Fire-X-Trol expansion chamber? A: Glycerine-water and propylene glycol-water mixtures. Q: What is a Wet Pipe Antifreeze system? A: Antifreeze systems are typically used as subsystems of a wet pipe system and are intended to protect small areas that could be exposed to freezing temperatures.

  17. FIRE-X-TROL FAQ’s Q: What happened to the recommended 40-gallon (151 liter) limit for antifreeze systems? A: This recommendation has been deleted in the NFPA 13 2002 edition. There is no limit to the size of an antifreeze system. Q: Is a reduced-pressure zone backflow prevention device required in an antifreeze system? A: Many local regulations require that a backflow prevention device be used in the system to guard against any potential contamination of the public water supply. Q: Is an expansion chamber required when a backflow prevention device is used? A: Yes. Section 7.5.3.3 of NFPA 13 requires the use of an expansion chamber.

  18. FIRE-X-TROL FAQ’s Q: Does antifreeze-water solution expand and contract? A: Yes. The solution will expand and contract with changes in temperature. The amount of expansion and contraction depends upon total temperature change and the density of the specific solution used. Q: Is the Fire-X-Trol UL Listed? A: Yes. The Fire-X-Trol is UL listed and was subject to extensive UL testing for compatibility with antifreeze solutions and to assure that the quality of the Fire-X-Trol meets fire protection standards. Q: What are the advantages of an AMTROL diaphragm tank? A: In extensive cyclic testing and with the performance proven AMTROL diaphragm technology, a diaphragm can typically accommodate 4X the cycles of a bladder style tank.
