SV22 – A Multi Zone System

Description
System Design

A deluge system consists of a network of dry pipework and open nozzles that is connected to a water supply through a normally closed on-off or a pressure regulating deluge valve. Every system standardly comes equipped with all necessary valves and instrumentation for operation, maintenance and testing purposes. The system can be customized to conform to any required safety integrity level and can be delivered full flow pre-tested. In addition to the Firenor standard design, the multi zone deluge system can be customized to meet specific project requirements. Customizations include deluge system piping on open frame or inside cabinet for environmental protection purposes, and the choice of pneumatic, hydraulic, or electrical signals for the release mechanism

Verification

Every system can be customized, upon request, for compliance with applicable rules, regulations and project specific requirements as well as standard such as CE, FM, UL, ASME, DIN, DNV, BV, NMD, IMO, NFPA, Norsok. Full documentation for any tailor-made products are available and include all necessary certifications, third party verifications such as DNV/GL, BV, ABS, etc., and full scale test reports, if required.

Foan Supply

The foam supply for this system can be provided by a separate tank outside or inside the skid, or from a central foam system, depending on the exact project specifications. The foam can be mixed with a variety of solutions listed below:

  • Turbine foam proportioner
  • Balanced pressure foam proportioner
  • Foam inductor
  • Constant flow orifice
Nozzles

Deluge skid nozzles can be supplied with the system and are available in options such as medium velocity, high velocity, and open sprinkler heads.
Firenor can design the nozzle placement for such a system and will carry out all necessary hydraulic calculations before installation and delivery.
