TOP 4 INSTALLER BENEFITS TO SWITCH TO A LISTED ANTIFREEZE BEFORE THE DEADLINE

NFPA standards require all antifreeze fire sprinkler systems to switch to a listed antifreeze by September 30, 2022. These standards help ensure that an antifreeze system performs reliably in a fire and saves more lives, rather than contributing to fire as unlisted fluids can.

HIGH-VOLUME SPRINKLER SYSTEMS AND LISTED ANTIFREEZE

Before July 2021, a listed antifreeze approved for use in Ordinary Hazard 1 & 2 sprinkler systems larger than 40 gallons did not exist, even though many of these buildings require a system with significantly more antifreeze. This limitation made it difficult and expensive for antifreeze-based fire sprinkler systems in larger applications to maintain compliance with NFPA requirements.

Why You Should Think About Sprinkler Freeze Protection This Summer

Planning for freezing temperatures during the sweltering summer might not be the first thing on anyone’s to-do list in the fire sector. But in the case of sprinkler system freeze protection, 2021 is the year it should be. Advance planning, insights from the field and a broad perspective on where winterizing is needed will be useful to prepare for safe, effective freeze protection in sprinklered applications this winter and next.

Using Antifreeze to Address Microbiologically Influenced Corrosion in Fire Sprinkler Systems

Fire sprinkler systems can be prone to a specific category of corrosion plaguing the industry known as microbiologically influenced corrosion, or MIC. According to the FM Global report “Corrosion and Corrosion Mitigation in Fire Protection Systems,” MIC is responsible for 10-30% of corrosion in all piping systems in the U.S.

When Is An Antifreeze Sprinkler System Better Than A Dry System?

During the years when there were no listed antifreezes to protect fire sprinklers from freezing in severely cold weather, dry pipe systems were often chosen to fill the void after NPFA put into place new regulations requiring listed antifreezes for new systems. The most common applications affected by this included attics, unheated warehouses, commercial freezers, overhead canopies, loading docks and parking garages. Now that listed antifreezes are commercially available, however, it’s worth evaluating experiences from the field where dry system use increased in situations where it might not have been best suited. While these systems can be the right solution in some scenarios, they can have significant drawbacks in others.

Where Can I Winterize Sprinkler Piping With freezemaster™ Antifreeze?

Sprinkler pipes must be safeguarded when temperatures cannot reliably remain at or above 40ºF (4ºC) ambient temperature. New and existing sprinkler systems in Residential, Light Hazard, Ordinary Hazard and Storage applications can be protected against severe cold with freezemaster™ antifreeze, a new UL-listed, factory premixed freeze protection technology.
