Storage Sprinklers
Storage sprinklers are large-orifice heads designed to deliver high water flow to fast-growing fires in high-piled and rack storage. Compared with standard sprinklers they produce larger droplets and higher flow so the water penetrates the fire plume and reaches the burning goods.
This group contains two families: large-orifice ELO sprinklers for fire control and ESFR sprinklers developed to suppress the fire at an early stage. Models in the store range have a ¾” connection.
Main Applications
- High-rack logistics warehouses
- Palletised and block storage areas
- Plastic and cardboard packaging stores
- Automated storage systems
- Large production halls

Which material? Storage sprinklers are selected from the fire design standard by ceiling height, storage height and commodity class; ESFR systems may reduce the need for in-rack sprinklers, but that decision depends on the project calculation.
Advantages
