Matrix and Monitech Announce Africa Partnership

Matrix Design Group, LLC (Matrix) announced today a partnership agreement with Brentwood Electronics T/A Monitech (Monitech) for distribution and integration of the Matrix product line, including proximity detection systems, to mines and other industrial operations in Africa. The partnership’s initial venture has delivered full section, leading-edge proximity detection solutions to Sasol Mining for some of its underground operations.

“Matrix is proud to team up with Monitech to deliver innovative technologies to the African market,” said Matrix President David Clardy. “Monitech’s premier technical service teams are highly respected in the African mining industry, and we are excited to be working with them.”

“Superior service, safety, integrity and technology are the core of our business at Monitech,” added Monitech President, Jarrod Hassett. “Matrix brings new technology solutions to the African mining industry, and together with commitment and local service from Monitech, African mining operators will find the Matrix systems to be the best performing, most reliable and lowest cost to own.”

Of particular interest to African mining operators, the IntelliZone proximity detection system is a state-of-the-art machine-integrated system that will automatically warn personnel if they are in close proximity to mobile machinery or entering an unsafe working area. The system’s advanced control system interfaces with machinery, providing the ability to slow down or stop the machine should personnel or other secondary machinery move into Warning or Shutdown (Red) Zones designated around the machine. The system is intended to enhance miners’ awareness of potentially dangerous areas around working machinery and instill safe operating practices.
