Deluge, water spray & foam systems
Deluge, water spray and foam protection for defined hazards, including exposure cooling, hydraulic demand and release arrangements

Engineering services (Deluge, water spray & foam)
Process equipment, exposed structures, storage risks and liquid fuel hazards can require a protection approach beyond conventional building sprinklers. The design brief must distinguish fire control, exposure cooling and other intended functions, then establish the applicable system and supply requirements.
System selection also depends on the protected materials, environmental conditions, concentrate compatibility, discharge arrangements and site operations. Foam selection and environmental or disposal requirements require project-specific review. No generic nozzle arrangement or product choice is assumed to suit every facility.
Scope of expertise
The appointment is defined around the facility, available information and required project outcomes. Relevant services can include:
- Deluge and fixed water spray design considerations
- Tank and equipment exposure-cooling requirements
- Foam application and distribution engineering within the agreed scope
- Nozzle, monitor and discharge-device coordination
- Hydraulic demand, release arrangements and firewater interfaces
- Concentrate compatibility, containment and environmental specialist interfaces
Design and deliverables
We establish the hazard information and protection objectives, develop the design basis and coordinate the system with the facility and firewater infrastructure. Specialist product evidence and vendor calculations are reviewed where included in the appointment.
Protection design basis and system requirements
Documents and engineering information appropriate to the defined appointment and project stage.
Hydraulic and specialist submission reviews
Recorded findings, requirements and matters for resolution by the responsible parties.
Project information
Provide process and storage details, site layouts, equipment dimensions, material information and the proposed operating arrangements. Identify existing protection systems and environmental constraints.
The scope, deliverables, site involvement and responsibilities are confirmed for each appointment.
Discuss your engineering requirementsNFPA 15 design support
FESOL provides water spray systems design and technical review to NFPA 15 where specified in the agreed project design basis. The appointment coordinates the relevant standard and edition with local requirements, project specifications and the supporting equipment information.
