Johnson Controls, the global pioneer for smart, healthy and sustainable buildings, launches the new Tyco® ESFR-25 Dry-Type Pendent Sprinkler offering efficient, FM Approved fire protection for commercial refrigerated and frozen storage areas.
The dry-type sprinkler is used in applications where the water is supplied from a wet system in an adjacent conditioned space. It is designed for dependable operation in cold storage areas up to 50 feet (15.2 meters) in height with temperatures as low as minus 60 F (−51°C).
Need for a fire pump
The ceiling-only, lower-pressure sprinkler provides flexibility and efficiency by reducing the need for a fire pump and eliminating the need for in-rack sprinklers when protecting high-piled storage within these box-in-box applications.
While an effective solution, traditional in-rack sprinkler systems can be complex and expensive. Obstructions and tight clearances can make installation difficult while daily operations such as shelving and retrieving products can damage in-rack sprinklers, resulting in potential downtime.

The new Tyco cold storage sprinkler is also designed to operate at lower-end head pressures
Innovative ceiling-only cold storage protection, like the Tyco ESFR-25 Dry-Type Sprinkler, operates without the need for in-rack sprinklers for an overall simpler and more affordable solution.
As box-in-box freezer storage facilities become taller to accommodate more products, reliable performance at ceiling heights of up to 50 feet offers greater peace of mind. This new Tyco cold storage sprinkler is also designed to operate at lower-end head pressures, reducing or even eliminating the need for a fire pump.
Cold storage sprinkler innovation
“By combining a 25.2 K-factor sprinkler with a dry-pipe design, we’ve introduced a tested and proven fire suppression solution for high-piled storage in commercial coolers and freezers,” said Beth Bjorlo, senior director, Fire Suppression Products at Johnson Controls.
“Backed by a history of trusted Tyco performance, this cold storage sprinkler innovation helps round out our industry-pioneering, full-building portfolio of fire suppression solutions.”
Range of cold storage applications
With the flexibility to meet a wide range of cold storage applications, the ESFR-25 sprinkler is the only early suppression, fast response dry-type sprinkler with a nominal K-factor of 25.2 that comes in both threaded connections (1-1/4-inch NPT or ISO 7-1) and grooved 2-inch connections. It’s also available with:
- Ordinary (165 F/74°C) and intermediate (212 F/100°C) temperature ratings
- 23-, 30- and 36-inch barrel lengths
- Included insulating seal assembly kit to help minimize condensation and ice buildup.
