Considered to be Tanzania's largest underground mining investment, Vector Drive Contracting of Canada specified Solcons' medium voltage soft-starters for the fresh air ventilation fans of this massive underground mining venture.

The Solcon HRVS-DN soft starter for medium voltage motors enables the engineer to regulate the inrush current on startup, allowing the motor to slowly transfer the power to the blower via the drive belts, ensuring that all the power is efficiently used to start the blower turning with no slipping.

The Solcon Soft-starter with its multi-start application was the ideal solution for this application. The HRVS-DN line-up is built in a Multi-Start arrangement, starting each of the 3 synchronous motors sequentially. One soft-starter for three motors saves precious space, engineering, construction, and installation costs.
