FireDos proportioners for Mining

In a mine in South Africa, FireDos foam proportioning systems type FD500, FD1000 and FD1600 are used at a depth of 6 km. The mine water poses a specific challenge when used underground.

Mining machines are often operated with highly flammable liquids. The fire protection requirements are correspondingly high. The South African mine uses compact FireDos proportioners supplied through DoseTech (PTY) LTD, of types FD500, FD1000 and FD1600 to protect the conveyor belts in case of fire. The units are part of a sprinkler extinguishing system with deluge valve. A one percent AFFF is used as foam concentrate.

Mounted on portable skids

For easy transport, the proportioning systems, foam concentrate tank and valves are mounted on portable skids, protected by a grid. Individual elements can be easily replaced during maintenance.

The greatest challenge: the mine water

The quality of the mine water is a critical factor when using the proportioning mixing systems in the mine. The lime content is very high. Over an extended period, the lime calcifies and can cause a potential blockage. For this reason, the water quality was carefully checked before installation. Regular maintenance and regular cleaning every 6 months are essential to ensure the safe operation of the units.
