Leading manufacturer of custom-engineered mobile power solutions, Zest WEG has supplied a
mobile switching station to Mozambique’s national power utility EDM (Electricidade de
Moçambique).
Classified as hazardous areas, offshore oil rigs require that any equipment installed on them is designed and certified accordingly – including electric motors to drive
Over the past 12 years Zest WEG, the South African subsidiary of Brazilian motor and controls manufacturer WEG, has evolved from being primarily a sales
Shutting down a whole process plant to attend to a single electrical problem means unnecessary downtime, says Foster Yeboah at Zest WEG’s Ghana branch. An innovative solution has recently been installed in Ghana to avoid this, using WEG’s fully withdrawable board – a pioneering step for Africa’s mining sector.
Further extending Zest WEG’s local manufacture of electrical equipment for mining and other sectors, a new assembly line for low voltage (LV) motors has been established. The facility is part of Zest WEG’s corporate premises at Longlake, east of Johannesburg. According to CEO Eduardo Werninghaus, the new line enhances operational flexibility and reduces lead times to customers.
Zest WEG progressively increased its level of local manufacturing over the past decade and now boasts six manufacturing sites – four in the Gauteng region and two in Cape Town.
Most of Zest WEG’s product offering will be on display at the upcoming Electra Mining Africa 2022 exhibition with the company’s theme being how to change energy into solutions. In addition to the range of WEG IE4-rated super-premium efficiency electric motors, Zest WEG will also showcase its high-tech solutions showing how far WEG has progressed on its digital journey.
One of the largest High Intensity Grinding (HIG) mills in the southern hemisphere is being powered using an E-House solution from Zest WEG, built to the highest safety and performance standards. Zest WEG senior proposals manager Tyrone Willemse highlights the E-House solution, constructed locally with a range of components -also produced and distributed by Zest WEG, must meet the aggressive torque requirements of the application.
The efficiency of electric motors has a key role to play in reducing users’ running costs, and in helping meet South Africa’s climate change goals. But with no local regulations in place to push this agenda, there needs to be more understanding among motor users about how their bottom lines can quickly benefit from shifting to IE3, IE4 and even IE5 electric motors, according to Zest WEG.
As power outages and loadshedding continue to plague the optimal performance of industrial and mining process plants, Zest WEG is providing standby power solutions that
The project to expand a wastewater treatment plant south of Johannesburg, undertaken by water purification specialist PCI Africa, has included the installation of 65 WEG motors to ensure optimal performance, reliability and energy efficiency.
Leveraging its considerable in-house expertise and local manufacturing capability, Zest WEG has custom designed and manufactured a mobile substation solution for the utility of Guinea – its biggest such mobile unit yet manufactured in South Africa. The innovative 50 MVA substation, with a dual voltage of 110-60/30-20 kV, will perform a range of duties for the Utility Company of Guinea, called Electricité De Guinée, including providing emergency and standby power.
Now one of the world’s highest-grade copper mines, Kamoa-Kakula in the Democratic Republic of Congo (DRC) is installing a wide range of WEG motors and variable speed drives (VSDs) for the second phase of its development. Zest WEG has already delivered on a similar scope for the mine’s first phase, which produced its first copper concentrate on 25 May 2021.
With concern growing that climate change will exacerbate South Africa’s vulnerability to drought, the country is likely to see more desalination plants being installed along
Zest WEG is supplying locally manufactured transformers, switchgear and substations to South Africa’s exciting onshore natural gas and helium project, Tetra4. Being developed by emerging producer Renergen near Virginia in the Free State province, the natural gas deposit reportedly contains world-beating concentrations of helium – up to 12% compared to typical levels of around 0,5%.
