GLYCOL SPRINKLER SYSTEMS
Glycol systems are charged with glycol. When a sprinkler head is actuated, the glycol is released, automatically allowing water to flow into the system. This system is combined with a wet-pipe sprinkler system.
Benefits and Applications
This lower-cost system protects small, unheated areas and areas subject to freezing conditions, including loading docks, small roof spaces, external dust collectors, etc.
