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.
freezemaster™ antifreeze’s minimum use temperature of -12ºF (-24ºC) makes it suitable for unlimited exterior uses in buildings in most areas of the United States and along the east and west coastal areas of Canada. These regions appear on or below the line in the graphic below, and include these cities and their surrounding areas:
Boston
Boise
Buffalo
Chicago
Cleveland
Detroit
Denver
Halifax
Indianapolis
Milwaukee
New York City
Omaha
Philadelphia
Pittsburgh
Portland
Salt Lake City
Seattle
Washington, D.C.
Vancouver, British Columbia
Partially Conditioned Spaces: Ideal for freezemasterTM Antifreeze
But what about northern areas of the U.S. and Canada where temperatures drop much lower than -12°F? On its own, listed antifreeze currently on the market would not maintain piping at an acceptable temperature in these areas. There are, however, thousands of partially conditioned interior spaces that are suitable candidates for freezemaster™ antifreeze.
Buildings with small unheated areas vulnerable to freezing often charge sprinkler pipes with water during the summer only. During the coldest months when there is a risk of freezing, the pipes are drained and charged with air under pressure. These spaces may be heated on average to 50ºF (10ºC), but can drop below freezing if an outside door is open or the heat can't keep up with severe cold at night. Structures outfitted with these “tail end” hybrid systems are good candidates for freezemaster™ antifreeze. They include:
- Small walk-in freezers and refrigerators
- Temperate small parking garages
- Small cold storage facilities
- Roof access hatches
- Basement garbage rooms
- Industrial refrigeration equipment
- Pits in heated buildings
- Surge areas
- The first few heads of a heated parking garage
- Obstruction heads below bay doors
- Tunnels/corridors in heated industrial applications with large diameter piping but not much heating capacity
With freezemasterTM antifreeze, compliance with NFPA requirements has never been easier. Precisely formulated by Lubrizol, a specialty chemical company supporting the fire industry for more than 30 years, freezemaster™ antifreeze delivers the safety, performance and assurance you can rely on with:
- A corrosion inhibitor package that effectively reduces pipe corrosion by up to 65%, including microbiologically induced corrosion (MIC)
- Unique blue coloring so contractors are able to see the material as it exits the vents and drains when flushing and filling systems
- An additional UL listing for use in galvanized piping systems
And of course, freezemaster™ antifreeze is backed by the expert support of Lubrizol so you get the assistance you need when you need it.
