Before NFPA Standards required the use of listed antifreeze solutions, installation, testing and maintenance (ITM) contractors could site-mix antifreeze fluids to meet the volume requirements of a system. But now NFPA guidelines stipulate factory-premixed, agency-listed antifreeze as a safer alternative to site-mixed fluid.

Piping materials for fire sprinkler systems vary based on budget, location, when the system was designed, contractor preference and more. Although more common in dry pipe fire sprinkler systems, there are many existing and new wet systems made with galvanized pipe. For these, there is only one UL-listed antifreeze approved for use with galvanized piping: freezemaster™ antifreeze.

It’s been 10 years since NFPA guidelines specified that site-mixed, unlisted antifreeze was no longer an approved option for wet systems. Because a listed alternative wasn’t yet widely available, new systems were almost exclusively designed as a dry system.

Because the primary purpose of antifreeze is to protect sprinkler systems from cold, contractors tend to only consider the minimum use temperature when selecting a listed antifreeze.

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.

When installing listed antifreeze, the manufacturer’s installation guide is the final word. But talking with installers who have already started switching their clients to a listed product has revealed three installation tips that you won’t find in the official installation guide.

A UL-listed, factory-premixed antifreeze – like freezemaster™ antifreeze – will soon be the new normal for sprinkler systems needing seasonal freeze protection. This new normal requires different installation and maintenance than building owners and ITM contractors are used to with traditional antifreezes. Not taking these differences into account significantly shortens the life of listed antifreeze.
