1. It is installed between the backflow preventer and fill cup

2. 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.

3. As the antifreeze solution temperature rises, expanded system fluid enters the Fire-X-Trol non-corrosive reservoir.

4. The Fire-X-Trol absorbs the pressure increase, keeping system pressure below maximum system rating.

5. 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.

• 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…”

1. Visually inspect FIRE-X-TROL for any damage.

2. Hydraulic system pressure must be at zero.

3. Attach nitrogen or dry air supply to expansion chamber charging valve

• Dry air: -50 F / -46 C dew point or lower

4. 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.

5. Remove charging hose. Carefully test charging valve for leakage.

6. Replace plastic cap.

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.

FIRE-X-TROLFIRE-X-TROL FAQ’s 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.



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.
