The new freezemaster antifreeze meets the requirements of UL 2901 to protect against corrosion and severe cold. freezemaster is now UL-listed and offers breakthrough corrosion resistance properties – a key determinant of whether a sprinkler system will reliably function.

It can be installed per its listing and serviced in all new and existing systems including Light Hazard, Ordinary Hazard and Storage applications.
