In-Rack Sprinkler Systems

Ultimate Fire Protection for Your Facility


A high-quality fire protection system is an essential component to having a successful warehouse operation. Warehouse fires can spread quickly, and cause costly damage to your stored goods. Fires can be especially dangerous in warehouses storing hazardous or flammable liquids or chemicals. Taking preventative measures is a must, which is why an in-rack sprinkler is a great investment to avoid future losses.

In-Rack Sprinkler Systems are a network of piping installed throughout your racking system. Although in-rack sprinklers can’t prevent fires from starting, they are fire-heat activated to contain and extinguish a fire within your racking system, limiting the amount of fire damage in your warehouse. In-rack sprinkler systems provide increased proximity to equipment as opposed to overhead sprinklers in your warehouse. Ultimately, the goal is to minimize as much fire damage as possible.


  • Increased proximity to equipment for fast acting fire suppression
  • Contains fires within specific area and extinguishes them quickly
  • Minimize downtime and damage to your facility, equipment, and inventory
  • Continuous monitoring for smoke and heat detection
  • Perfect for facilities with large industrial shelving and racking systems
  • Reduced installation costs compared to traditional ESFR sprinkler systems
  • Efficient use of extinguishing agent, resulting in reduced overall cost
