Complete ventilation solution offered more efficient in their performance but are also tailored to deliver the required air at the required time. For example, a fan that is designed to have different degrees of control in order to meet the specific levels of ventilation required for increased ambient temperature or activity or when measured pollutants move beyond a pre- set tolerance.”

the initial purchase price. To do this, we rely on superior technology derived from our parent company TLT-Turbo,” Johnston explains. He elaborates with an example of how innovation ensures that clients see a return on investment. “As part of a recent study, TLT ACTOM proposed to replace two existing mine ventilation fans with a single axial fan. Because of its higher efficiency, it will save approximately 500 kW. The calculated annual energy saving is R3,6 million, making the payback extremely attractive.” The current installed base of process and ventilation fans is aging, and in tough times this equipment has to be carefully maintained to achieve the expected life of product. To achieve this, TLT ACTOM provides a dedicated skilled team of fan specialists to monitor and maintain installed systems. “Where replacements are required, we offer the value added service of critically analysing the existing plant and using an intellectual approach to offer improve- ments, for example, in efficiency, size correction or wear durability. Wherever possible, this is achieved without replac- ing the entire fan but in retrofitting the rotating element with minor modifi- cations, thus minimising the capital spend for the customer and ensuring an acceptable return on investment,” says Johnston.

In a significant development that boosts local content, Multotec has built the capacity of its Botswana office to conduct light fabrication at the request of custom- ers, rather than sending this work to South Africa. This kind of work, on screening media products as well as wear-related and peripheral products such as mill-feed chutes, discharge chutes and pipes, can now conveniently be done close to the customer during a scheduled plant main- tenance shutdown. Mine staff can also be supported in the installation process. Bernadette Wilson, Multotec Group, tel (+27 11) 923-6193

TLT ACTOM aims to offer South Africa’s mining and power sector more than just innovative ventilation fans. It says its cus- tomised systems ensure that working conditions are safe and energy efficiency maximised as part of a holistic ‘Total Ventilation Solution’ that aims to reduce total cost of ownership. Operations Director Craig Johnston believes that TLT ACTOM’s approach is ideal for addressing the concerns of the Southern African market. “We have come to realise that in Southern Africa power is becoming a far higher input cost in our industries and processes than it was in the past,” he says. “TLT ACTOM prides itself on applying innovative, lateral thinking to solutions that save energy by offering the best efficiency selections for the applications. We can supply products that are not only

TLT ACTOM’s Total Ventilation Solution approach aims to provide complete solu- tions to the challenges of underground mines, thermal power plants and numer- ous industrial process applications including cement production and waste incineration. “Capital cost is one aspect that cli- ents are most heavily focused on but TLT ACTOM strives for excellence in power efficiency, maintainability and life expec- tancy – all factors that can easily outweigh

Multotec launches as a fully Botswanan company After five years of successfully growing its market in Botswana, mineral processing solutions provider Multotec will now be relaunching as a fully-fledged subsidiary – locally registered and rooted in Botswana. “With our head office in Letlhakane and additional site offices at Jwaneng, Orapa and Letlhakane diamond mines, Multotec’s success in this region has been built on staying close to our customers,” says Kris Vergote, General Manager for Multotec Botswana. “We are now also an active part of the local community and have created employment for 148 local residents.”

his 20 years of operational plant experi- ence to the capacity of the management team. According to Multotec Africa MD Jaco du Toit, the company’s proximity to cus- tomers allows high levels of technical and maintenance backup. The Botswana premises include 1 350 m 2 , 350 of these under cover, dedicated to stockholding. This effectively reduces lead times and ensures that a customer is never kept waiting for parts. “Our personnel are at customers’ sites on a daily basis, so there is always strong technical expertise on the ground,” says Du Toit. “While the metallurgists and plant experts in the Letlhakane office manage our maintenance contracts, they are, in turn, supported by product specialists in

With 23 years of industry experience, Vergote is supported by metallurgist Kennedy Maputla in the role of Sales and Contracts Manager; Allen Roussouw, the company’s Field Services Manager, adds
