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.

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.

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.

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.

NFPA fire sprinkler standards require new antifreeze systems to use an agency-listed antifreeze. And these same standards require that existing systems use an agency-listed antifreeze by September 30, 2022. These standards are intended to ensure an antifreeze system is designed and installed using the safest and most reliable practices in the industry.
