The Upright Sprinklers are Early Suppression, Fast Response (ESFR) sprinklers with a nominal K-factor of 16.8. They are suppression mode sprinklers that are especially advantageous as a means of eliminating in-rack sprinklers when protecting high-piled storage.
The Upright Sprinklers are primarily used for ceiling-only sprinkler protection of the following storage applications:
- Most encapsulated or non-encapsulated common materials, including cartoned, unexpanded plastics
- Cartoned, expanded plastics
- Some storage arrangements of rubber tires and roll paper
For more specific criteria, refer to Table A in this technical data sheet as well as the applicable design standard.
The Upright Sprinklers offer several advantages over traditional pendent ESFR sprinklers, including:
- A higher K-factor, which provides system designers with hydraulic and sprinkler placement options not presently available to traditional ESFR sprinklers.
- The ability to operate at substantially lower-end head pressures, which offers flexibility when sizing system piping and positioning the system piping with respect to the ceiling.
