Danfoss continues to invest in sustainable transformation
First Quarter 2021
News & events
There has been growing momentum in the energy sector, and governments across the world are committing to a transition to low-carbon economies. At the recent opening of the Investing in Africa Mining Indaba, president Cyril Ramaphosa implored mining entities to invest in sustainable energy resources. This sentiment has been echoed by minister Gwede Mantashe and the Department of Mineral Resources and Energy (DMRE). However, securing the environmental benefits arising from mining and energy developments is challenging, and at times it restricts innovation within these sectors.
The industrial sector is responsible for 20% of total greenhouse gas emissions. This creates the opportunity to rethink our industries and to build resilience and increase competitiveness, while reducing emissions and paving the way towards a carbon-neutral future. The smart solutions that reduce energy consumption, improve productivity and help integrate renewable energy sources are available today. The World Bank estimates that mining of minerals like graphite, lithium and cobalt will grow by 500% in the next three decades to meet demand for clean energy technologies.
Variable speed/frequency drives (VFD) are expanding their use as the starter of choice, not only in applications that require speed control but also in applications that require torque control and mechanical soft starting. The VFD has the capability to perform active load sharing between multiple motors on the same operating system, allowing one VFD to assume the function of a master and others as the follower, so when the master’s torque increases, the follower’s torque limit increases, allowing it to contribute more torque to the load.
With this in mind, Danfoss Drives South Africa rolled out a series of thought leadership webinars on the topic of energy efficiency in 2020. The campaign’s overwhelming success with international audiences led to it being extended into 2021. This year the webinars will focus on technologies that optimise energy consumption and longevity of drive components in the mining industry.
Here are the registration links to the first webinars:
