EPG Services to move into Africa Vert Energy is set to further expand its Electric Pow- er Generation (EPG) services to generator set build- ers and end users throughout Africa. “Vert Energy provides a standby and power solu- tions service to companies and communities, even those in the most isolated regions. Through an exten- sive range of quality branded EPG products, support- ed by a skilled team of technical experts, the compa- ny plays a major role in providing dependable power in areas that are off-grid and where power supply is

not constant, or reliable,” says Vert Energy’s managing director, Grant Robertson. “Vert Ener- gy teamed up with the DEIF Group over three years ago as exclusive distributors in sub-Sa- haran Africa, of DEIF generator controls, known globally for critical power and decentralised power applications. “This partnership has been boosted with the recent appointment of Gaëtan Floriach, a highly qualified DEIF engineer, who is based at Vert Energy in Johannesburg for a two year period, to further develop DEIF business in Africa. “Apart from the supply and support of power generation components for diesel and gas engines, Vert Energy’s service focuses on companies investing in alternative sources of elec- tricity production, particularly solar power. “The growing trend to utilise environmentally-friendly photovoltaic (PV) technology to con- vert solar energy to electricity, requires dependable power generation systems, which need to be supported by technically competent skills.

Dry-type transformers now in Africa

According to Trafo Power Solutions managing di- rector, David Claassen, dry-type transformers are safer and more efficient than their oil-filled equiv- alents, factors that make them a cost effective and versatile choice in a range of applications and sec- tors. “The high safety rating of dry-type transformers allows them to be installed indoors, avoiding the cost and inconvenience of the special structures normally required to accommodate the safety and environmental hazards related to oil-filled units,” says Claassen. “Dry-cooled transformers are cate- gorised as F1 in terms of international fire resist- ance ratings, making them low-risk as they are self-extinguishing and flame-retardant by nature,” he says. The technology also serves a growing demand for more energy -efficient solutions, especially as the price of electricity has risen dramatically in South Africa and many economies on the continent. Less maintenance is another advantage; dry- type transformers are low in maintenance and could last for 25 years without significant attention, while oil-filled transformers require regular maintenance including oil sample analysis to ensure operational consistency and safety.
