Marmora Electric Monitor

Marmora Electric Monitor supplied by SA Fire Protection

The model Marmora electric is a remote- controlled monitor with single water way body. The monitor is capable of withstanding flows up to 30000 lpm (7800 gpm) and may be base flanged 4”, 6”, 8” o 10” UNI or ANSI. Movements on the vertical & horizontal plane are performed by electric actuators that transfer the force through a gearbox to the monitor joints.

The joints are built using a double channel system that host the rotational spheres. The body is designed to balance the reaction force and couple the monitor with several different discharge outlets such as water branch pipes, foam branch pipes and nozzles.

The Marmora electric is suitable for installation within hazardous area classified ATEX zone 1 G and zone 21 D. The material of construction makes it suitable for being used with sea water or water foam solution within industrial harsh environments & offshore applications.
