Johnson Controls, the architect of OpenBlue connected solutions, is releasing two new Tyco early-suppression, fast-response (ESFR) Rapid Install Sprinklers (RIS) for protection of warehouse and storage facilities. The Model ESFR-22 and Model ESFR-25 pendent sprinklers and their accompanying custom-welded outlet fitting, simplify installation for fire protection contractors by featuring pre-installed rubber gaskets and a thread connection that can be installed by hand with no need for tools, tape or sealant.
“We saw significant cost savings using the ESFR-25 RIS in a small portion of our install,” said Chris Holland, general manager, Advanco Fire Protection. “Quantify that across a larger project and the savings will multiply exponentially.”
The ESFR-22 RIS (22.4 K-factor) and ESFR-25 RIS (25.2 K-factor) both provide warehouse design flexibility by eliminating the use of in-rack sprinklers when protecting high-piled storage. The ESFR-22 RIS and ESFR-25 RIS are cULus Listed and FM Approved for specific applications with a maximum storage height of 13,1 m and a maximum ceiling height of 14,6 m without the requirement for in-rack sprinklers. Both sprinklers permit the use of a maximum deflector-to-ceiling distance of 460 mm, compared to 356 mm distance for ESFR sprinklers with K-factors of 14.0 and 16.8.
“These new ESFR Rapid Install Sprinklers give system designers sprinkler placement options not currently available with traditional ESFR sprinklers with lower K-factors,” said Don Ricca, global product director, Johnson Controls. “These sprinklers are designed to operate at substantially lower-end head pressures, which offers flexibility for contractors when sizing system piping, as well as possibly reducing or eliminating the need for a system pump.”
Tyco ESFR Rapid Install Sprinklers are ideal for ceiling-only sprinkler protection of warehouses and storage facilities containing cartoned and unexpanded plastics, exposed and expanded plastics (in accordance with NFPA 13 and FM Global standards) and some storage arrangements of rubber tyres, roll paper, flammable liquids, aerosols and automotive components.
