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.

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.
