Fire Sprinklers

FIRE SPRINKLERS

Fire nozzles are essential firefighting tools attached to hoses to control water flow, pressure, and spray patterns—typically straight stream or fog—for effective fire suppression. Common types include durable brass or thermoplastic nozzles, with 1.5-inch and 2.5-inch sizes being standard for industrial and brigade use. 
  • PENDANT SPRINKLERS
  • SIDEWALL SPRINKLERS
  • CONCEALED SPRINKLERS
  • ESFR SPRINKLERS
  • ECOH SPRINKLERS

standard response pendent sprinkler is usually used in all hazard occupancies. The deflector is installed below the orifice, and the water spray is directed downwards against the deflector.

  • Certificate: UL Listed / FM Approved
  • Standard: UL 199, NFPA 13
  • Feature: K5.6 (K80), SR, pendent
  • W. pressure: 250 / 175 psi
  • T. pressure: 500 psi, factory hydrostatic test
  • O. pressure: Min 7 psi
  • Surface: Rough brass / chrome plated / white painted, etc.

horizontal sidewall sprinkler is usually used in light and ordinary hazard occupancies. The deflector discharges most of the water in a horizontal plane onto adjacent walls and the protected area.

  • Certificate: UL Listed / FM Approved
  • Standard: UL 199, NFPA 13
  • Feature: K5.6 (K80), QR, HSW
  • W. pressure: 250 psi
  • T. pressure: 500 psi, factory hydrostatic test
  • O. pressure: Min 7 psi
  • Surface: Rough brass / chrome plated / white painted, etc.

concealed pendent sprinkler incorporates a cover plate to conceal operational parts for aesthetic consideration. When exposed to specific temperature of fire, cover plate falls away and deflector is released to work similar as recessed sprinkler.

  • Certificate: UL Listed
  • Standard: UL 199, NFPA 13
  • Feature: K8.0 (K115), QR, adjustable concealed pendent
  • W. pressure: 175 psi
  • T. pressure: 500 psi, factory hydrostatic test
  • O. pressure: Min 7 psi
  • Surface: Rough brass for sprinkler, chromed plated / white painted / others for cover plate

 

ESFR (Early suppression fast response) pendent sprinkler is designed to offer extremely fast response for specific high-challenge fire hazards. It discharges large volumes of water in short time to suppress rather than control fire.

  • Certificate: UL Listed / FM Approved
  • Standard: UL 199, NFPA 13
  • Feature: K14.0 (K202), ESFR, pendent
  • W. pressure: 175 psi
  • T. pressure: 500 psi, factory hydrostatic test
  • O. pressure: Refer to NFPA 13 / FM spec.
  • Surface: Rough brass

 

ECOH (Extended coverage ordinary hazard) upright sprinkler is designed for use in ordinary hazard occupancies, and it provides max coverage area of 400 ft2 (37.2 m2) as NFPA 13.

  • Certificate: UL Listed
  • Standard: UL 199, NFPA 13
  • Feature: K14.0 (K202), ECOH, min spacing 8 ft
  • W. pressure: 175 psi
  • T. pressure: 500 psi, factory hydrostatic test
  • O. pressure: Min 7 psi
  • Surface: Rough brass / chrome plated / white painted, etc.
