FireFighter ® Antifreeze

FireFighter Antifreeze

Factory Pre-mixed Antifreeze for Wet Fire Sprinkler Systems

FireFighter non-toxicQ antifreeze solutions are designed specifically for wet fire sprinkler systems.
Use in place of water and other water-like fluids in sprinkler systems where freezing may either cause
damage or interfere with the functioning of systems or equipment, and/or toxicity to humans or animals
is a concern.

FireFighter® GL38
FireFighter GL38 is a non-toxic, glycerine-based
antifreeze for use in all types of wet fire sprinkler
systems, including CPVC. FireFighter GL38 isfactory pre-mixed to NFPA guidelines of a 38%
glycerine solution.

FireFighter® GL48
FireFighter GL48 is a non-toxic, glycerine-based
antifreeze for use in all types of wet fire sprinkler
systems, including CPVC. FireFighter GL48 isfactory pre-mixed to NFPA guidelines of a 48%
glycerine solution. Certified by NSF for use withBlazeMaster® CPVC.
When using glycerine in metallic pipe systems, or any situation where threaded connections exist, be aware that the molecular structure of glycerine
relative to water may allow glycerine to seep out of connections which are loose or poorly sealed, even if water alone does not seep out of thesystem. Seepage will reduce glycerine concentration and decrease the level of freeze protection.

Freeze Point is the temperature where the first ice crystal forms in the fluid. Burst point is thetemperature where the fluid is solid, expanding, and bursting the vessel. Minimum burst pointis the temperature where the fluid is at a hard freeze. *Specific gravity measured at 77°F/25°C.
**Boiling point, density, and viscosity are measured at atmospheric pressure of 760mm. ***Firepoint measured using Pensky-Martens Closed Cup test.

NFPA 25 requires that the freezing point of the system be tested at least once a year.
Periodic testing of systems is critical to maintaining the proper concentration and freeze point of the fluid. Leaks, pressure surges,
and temperature changes to the system can cause antifreeze to flow out of the system or water to flow into the system changing thefreeze temperature.
TESTING FIREFIGHTER ANTIFREEZE
To test the freeze protection level of FireFighter GL38 and GL48
and FireFighter PG30 and PG38, the correct instrument must
be used.
For testing FireFighter GL38 and GL48, Noble Company offers
two instruments:
1) A laboratory grade hydrometer2) A digital refractometer
For testing FireFighter PG30 and PG38, Noble Company offers
two instruments:
1) An analog refractometer2) A digital refractometer
When testing indicates that the solution has weakened, drain
the system according to NFPA requirements and replace with
new FireFighter GL38, GL48, PG30, or PG38 according to theinstallation instructions and all NFPA requirements. Do not add
concentrate or dilute.
For further information concerning correct testing procedures
and test instruments, contact our technical services department
and ask for “How to Choose the Correct Antifreeze Loop Tester,”or visit our website, www.noblecompany.com.

NFPA requires a tag to be affixed to the riser indicating the datetested or replaced, the type and concentration by volume of fluid
used, system capacity (in volume), contractor name and license
number, and a statement indicating if the entire system wasdrained and replaced with antifreeze. Tags are available free ofcharge from Noble Company or your local FireFighter distributor.
