System Architecture: Pumps, Valves, Nozzles
A high-pressure water mist system is only as good as its weakest component. Every part of the flow path — from tank to nozzle — is selected and tested to hold 50–140 bar continuously under fire conditions.
Component
HP pump unit
The pump unit generates and holds system pressure across the full discharge duration, with duty/standby redundancy sized to the largest protected zone.
Component
Section valves
Section valves isolate the system into independently activated zones, so only the zone containing the fire discharges — critical in long tunnel runs where flooding an entire bore wastes water and time.
Component
Nozzles
Stainless nozzles atomise water at the design K-factor for each application, producing the droplet spectrum the application requires.
Per-model K-factors and coverage limits are stated in the system documentation supplied with each design.
Component
Distribution tubing
SS316 stainless steel tubing carries water from valve manifold to nozzle in small-bore stainless tubing, keeping the distribution network light and retrofit-friendly compared to large sprinkler mains.
Integration
Detection & control
Systems integrate with flame, heat and linear heat detection to trigger the correct zone automatically, with manual release and full status reporting to the site fire panel.
Quality
Commissioning & hydrostatic testing
Every pump skid is hydrostatically tested to 1.5× working pressure before it ships, and every installed system is commissioned against its design zone map before handover.
