ESFR Sprinklers
An ESFR (early suppression fast response) sprinkler is a storage sprinkler that opens before the fire grows and aims to suppress it with high-flow, large-droplet water. Its goal is not only to keep the fire under control but to bring it to the point of extinguishment.
The store range has pendent and upright ESFR sprinklers with 74 °C and 96 °C ratings and ¾” connection. They are used in high-rack warehouses protected from the ceiling, within the height limits allowed by the design standard.
Main Applications
- High-rack warehouses
- Logistics and distribution centres
- Plastic goods stores
- Projects aiming to reduce in-rack sprinklers

Which material? In ESFR systems roof slope, obstructions and the clearance between sprinkler and storage directly affect performance; installation rules must be taken from the design standard and the selected model’s datasheet.

How to Choose?
- Check height limitsCompare ceiling and storage heights with the design standard.
- Review obstructionsMake sure beams, ducts and lights do not block the spray.
- Select the ratingConsider 74 °C for normal stores and 96 °C under hot roofs.
- Confirm the water supplyCheck pump and tank capacity against ESFR flow.
