Based on the system configuration, DiFFS can be set to operate automatically or manually. On system activation; a valve operates – allowing water to flow through a water turbine foam pump or inline inductor thereby discharging a correct admixture of foam/water solution (i.e. 1% or 3%) through an array of nozzles installed on the helipad / helideck, thus providing an effective spray distribution covering the entire deck surface.
Deck Integrated Fire Fighting System (DiFF System)
DiFFS system is primarily used as a firefighting system for helipad / helideck.
1. All skids are provided with SS-316 piping as standard. Various material options are available such as SS-316L, Copper nickel, Super Duplex, Titanium.
2. K3GS a unique first Non-Pop-Up Nozzle with UL Listing, CAAI and ABS Certification is available with various ‘K’ Factors suitable for most type and size of helidecks.
3. Foam skids are available with various combination such as Inline Inductor, Water motor foam pump, ratio controller, Balanced pressure foam proportioner.
4. DiFFS Nozzle is UL listed and CAAI and HCA certified. The complete system including skid and nozzle is ABS certified allowing reduced design review time. System complies with latest CAP-437 Requirement, NORSOK standard. Other certification such as DNVGL, BV, LRS, NORSOK, NMD are available based on project requirement.
5. System is customised type with various isolation valve configuration which are typically butterfly valve and deluge valve. These valves can be operated electrically, pneumatically based on customer requirement.
