HI-FOG® for Ro-Ro decks

Ro-Ro decks and special category spaces can be protected by a HI-FOG® sprinkler or deluge system. The system type is chosen based on the vessel type and size, as well as the layout of the car decks.

The basic components of both systems are the same. Both typically use the modular HI-FOG® electric pump unit (SPU) and have either HI-FOG® sprinkler or spray heads. The number of pump modules and exact type of sprinkler or spray head depends on the size and required flow for the protected space. Where the systems differ is in the activation.

HI-FOG® sprinkler system

The HI-FOG® sprinkler system is an automatic system that uses wet tubing. The system uses sprinkler heads with heat-sensitive bulbs. When a sprinkler bulb breaks, the pressure in the system drops, creating a flow through the section valves which starts the pump unit.

HI-FOG® deluge system

The HI-FOG® deluge system uses section valves that are normally closed, with dry tubing behind the valves. Open spray heads are released in sections when activated. The activation can be manual or automatic using an external signal from a fire detection system.
