System design and configuration
In case of fire in a container, the Unitor XFlow® water mist lance and the water monitor can be used together or independently.
The water mist lance tool case contains a battery operated drill, a fire hose and the lance itself.
The equipment can easily be carried, mounted and operated by one person. The lance is connected to the fire main using the hose in the tool case, and water is released by pushing the valve handle. With the drill, it is easy and fast to drill a hole in the container wall, preferably quite high up on the wall.
The lance is then inserted in the hole, and the groove in the fixing sleeve fastens in the container wall. It can operate unattended as long as needed.
The monitor can be placed on deck or other horizontal surface without any straps or fastening devises. It is however fitted with a strap that can be used if the ship is rolling or pitching in heavy seas.
The monitor is connected to the fire main with a standard fire hose, and start operating as soon as the hydrant valve is opened. The angle of the water jet is easily adjusted by a turning wheel, from 0° to 90%, and the direction is set by turning the monitor. The monitor stays stable by itself, and can operate as long as needed unattended.

Rules and regulations
Both the Unitor XFlow® mobile water monitor and the Unitor XFlow® water mist lance are type approved according to IMO regulations under SOLAS II-2/10.7.3 and the mobile monitor is tested and approved to meet the SOLAS regulations IMO MSC.1/ Circ. 1472.
The new regulation states that vessels carrying containers on or above the weather deck, constructed on or after January 2016 shall carry at least one water mist lance. Regulation states that vessels designed to carry five or more tiers of containers on or above the weather deck, shall carry a number of mobile water monitors in addition to the water mist lance(s):
- Min 2pcs when ship breath <30 meters
- Min 4 pcs when ship breath >=30 meter
The water mobile monitor is subject for onboard test to satisfaction of Administration, verifying that the water mobile monitor jet reaches the top tier of containers with all required monitors and water jests from fire hoses operated simultanously
Fleet of container ships gradually grows over the time. Ships become larger. Number of fire accidents on board container ships also increases. As the result of the Formal Safety Assessment (FSA) provided to attention of MSC at IMO, it was agreed that fire protection of new cargo ships with conteinerized cargo on deck should be improved. Therefore additional firefighting equipment is required to be carried on board as specified by SOLAS reg. II-2/10.7.3
Extinguishing fire using water
The Unitor XFlow water mist system creates a mist of fine water droplets. Droplets in variable sizes circulate in the airflow, suppressing the supply of oxygen and absorbing the heat energy, and thereby breaking the chain of combustion.
Water is an effective agent for fire fighting as it is readily available and environmentally friendly. When water is added as mist it is most efficient at reducing and dissipating heat and thereby controlling, suppressing and extinguishing a fire.
