Abstract
An antifreeze composition and a sprinkler system containing the antifreeze composition are described. Examples include aqueous antifreeze compositions containing relatively low amounts of glycerin and/or glycols, and which further include additives that are relatively non-flammable compared to glycerin and glycols. The additives are generally compatible with each other in the antifreeze compositions. Examples of the antifreeze compositions are typically relatively non-flammable, have low electrical conductivity and low corrosivity, and are compatible with CPVC.
