Specifically designed for the protection of racked storage areas, in-rack sprinkler systems are manufactured to continuously monitor for smoke and release water into a targeted area to minimize damage and downtime for the facility. Detectors are placed within close proximity to stored materials and equipment for the quickest possible response in the event of a fire. This is ideal for facilities that use large industrial shelving because it ensures that fires that begin in the middle of the rack can be extinguished before it consumes surrounding materials on other shelves or adjacent racks.
