In-rack fire sprinkler systems are a crucial component of warehouse fire protection, specifically designed to safeguard racked storage areas.
Unlike traditional fire suppression systems, which cover larger spaces, in-rack systems target fires at their point of origin within the storage racks.
This article provides an overview of in-rack fire sprinkler systems, including their features, benefits, types, and best practices for implementation.
What Are In-Rack Fire Sprinkler Systems?
In-rack fire sprinkler systems are specialised fire protection mechanisms installed directly within racked storage areas.
These systems are strategically placed close to stored materials and equipment to detect and suppress fires quickly and efficiently.
When a fire is detected, the sprinklers release water directly into the affected area, helping to suppress the fire and prevent it from spreading to adjacent racks or shelves.
These systems are especially useful in warehouses with tall storage racks or automated storage and retrieval systems, where traditional fire suppression methods may not be as effective.
By containing fires at their source, these fire sprinkler systems help minimise damage, protect valuable inventory, and ensure the safety of personnel.
Key Benefits of In-Rack Fire Sprinkler Systems
There are several benefits to installing in-rack fire sprinkler systems in warehouses and other storage facilities:
1. Targeted Fire Suppression
In-rack sprinkler systems focus on the area where a fire starts, ensuring that only the affected rack or section is targeted.
This design reduces the risk of water damage to other goods and materials unaffected by the fire.
2. Cost Efficiency
Compared to traditional fire suppression systems, in-rack fire sprinkler systems often require less water and extinguishing agents.
Because they are designed to target specific areas rather than flooding an entire room, the cost of recharging the system after a fire is significantly reduced.
Additionally, these systems are modular, allowing for easy installation and expansion as a facility’s storage needs change.
3. Quick Response Time
Professionals install in-rack fire sprinkler systems near the stored materials to ensure rapid detection and response during a fire.
This proximity allows the system to activate quickly, reducing the time it takes to control and extinguish a fire, thereby reducing potential damage and downtime.

Types of In-Rack Fire Sprinkler Systems
There are several types of in-rack fire sprinkler systems, each made to meet specific needs and conditions within a warehouse environment.
1. Wet Pipe Systems
Wet pipe systems, the most common type, constantly maintain water in the pipes, ready to release it immediately when the system detects a fire.
These systems are highly effective in environments where freezing temperatures are not a concern. They are also among the least expensive systems to install and maintain.
2. Dry Pipe Systems
Dry pipe systems prevent the water in pipes from freezing in environments with temperatures that may drop below freezing.
It uses air or nitrogen to pressurise the pipes and activate water flow when it detects a fire. Although they have higher installation costs, they are essential for warehouses in colder climates.
3. Pre-Action Systems
Pre-action systems are ideal for environments where accidental water discharge needs to be minimised. These systems combine elements of wet and dry pipe systems and keep the pipes dry until they detect a fire.
Once activated, the system fills the pipes with water before the sprinklers discharge, providing a reliable option for facilities with sensitive materials.
4. Deluge Systems
Deluge systems are designed for high-risk areas requiring rapid water deployment. When the system detects a fire, it triggers electrically controlled valves to quickly release a large volume of water.
These systems are used in areas with highly flammable materials where immediate fire suppression is critical.
5. Foam-Water Systems
For warehouses storing high-hazard materials, such as flammable liquids, foam-water systems combine water with a foam concentrate to suppress flames and toxic smoke.
They effectively control fires involving hazardous materials and require less water than traditional systems.

Choosing the Right In-Rack Fire Sprinkler System for Your Warehouse
Selecting the appropriate in-rack fire sprinkler system depends on several factors, including:
- the type of materials stored,
- the warehouse layout, and
- environmental conditions.
For instance, wet pipe systems may be suitable for standard environments, while dry pipe or pre-action systems are better for colder or more sensitive settings.
It is crucial to work closely with a fire suppression contractor who can assess your specific needs and recommend the best solution.
