What Makes Us Different
No Minimum Pressure Requirements
While other listed antifreeze brands may require a minimum system pressure of 20 psi, freezemaster™ antifreeze has no minimum pressure requirement, other than that of the sprinkler head.
UL Listing for Galvanized Steel
Unlike some other listed antifreezes, freezemaster™ antifreeze is UL listed for galvanized steel piping systems.
Proven Corrosion Inhibition Up to 65%
freezemaster™ antifreeze exceeds UL 2901 corrosion inhibition requirements, effectively reducing corrosion by up to 65%, including microbiologically induced corrosion (MIC).
Tinted Blue for Easier Identification
freezemaster™ antifreeze has a unique blue tint that cannot be confused with pure water, like clear antifreeze, or rusty water, like orange.
