The company has a second smaller manufacturing facility in Birmingham in the UK focusing on speciality products. “We pride ourselves on the fact that we produce every single component of our products. From design to manufacture and servicing, everything is done in-house. We hardly rebrand other company’s components as our own. We have to be sure of the quality of the products we sell, and the only way to guarantee this..., 27 Jun 2017 08:49:42 GMTI-CAT is at the forefront of fire-protection innovation for miningRecent tests conducted by Sasol and I-CAT have proven conclusively that dry chemical powder extinguishers are ineffective against rubber fires and conveyor belt and tyre fires, both encountered in underground mining. This means that many underground mines have little or no fire protection, posing a major health and safety risk to mineworkers. In addition, activating a dry chemical powder extinguisher in a confined space underground can result in an inhalation risk for operators and bystanders. The dry chemical powder can also contaminate the air-circulation system underground, and further erode mechanical and electrical parts on machinery, causing long-term damage. While safety has always been a critical factor in the mining industry, the tight economic climate has placed increasing pressure on the industry’s bottom line. While most mines tend to comply with the required fire regulations, few conduct proper risk-based fire protection implementation. “To enhance the..., 27 Jun 2017 08:44:02 GMTAutomotive industry to phase out environmentally-unfriendly refrigerantsIn line with the latest legislation in Europe, which came into effect at the beginning of the year, the automotive industry is required to phase out current environment-damaging refrigerants being used, and replace these with green alternatives. Automotive air-conditioning systems currently run on R134a refrigerant. However, HFO1234yf has been introduced as the next-generation gas for car air-conditioners, according to speciality chemicals and gas supplier A-Gas South Africa. R134a, or 1,1,1,2-tetrafluoroethane, is a haloalkane refrigerant with thermodynamic properties similar to R12 (dichlorodifluoromethane), but with insignificant ozone depletion potential, and a somewhat lower Global Warming Potential (GWP) of 1 300, compared to 2 400 for R12. HFO1234yf, or 2,3,3,3-Tetrafluoropropene, is the first in a new class of refrigerants with a GWP rating one 335th that of R134a, and an atmospheric lifespan about 400 times shorter. HFO1234yf has similar cooling properties to R134a, which..., 26 Jun 2017 09:01:39 GMTBearings International appoints new Financial DirectorLeading distributor Bearings International (BI), a member of the Hudaco Group, has appointed Widor Grobbelaar as its new Financial Director, with effect from 1 April 2017.

The project showcased the efficiency and speed of using rope access to carry out critical inspection work in a difficult mine operating environment. A five-man team from the Johannesburg-based rope access specialist conducted an internal inspection of two secondary cyclones at the mine’s roaster plant. The inspection focused mainly on determining the condition of the refractory material inside the cyclones, which had been decommissioned for five years. “The team took extensive photographs for the purposes of compiling a detailed report for the client,” Skyriders Marketing Manager Mike Zinn comments. The aim of the report is to guide the client in what repairs and materials are necessary to get the cyclones up and running again. Such information is critical in terms of long-term strategic planning for Syama. The Skyriders rope access team..., 23 Jun 2017 08:53:03 GMTFire detection and prevention in server roomsThe installation of proper fire detection and suppression systems is critical in hi-tech areas such as server rooms, in order to protect both costly equipment and valuable data in the event of any fire. Fire detection in such a critical environment has to take into account myriad factors, from the actual value of the equipment and the data it contains, to the potential sources of ignition, which includes the presence of electricity. “More often than not it is the data and equipment you want to preserve,” ASP Fire CEO Michael van Niekerk points out. Here a gas fire-suppression system is the best option due to the sensitivity of the equipment. “Obviously, a sprinkler or water-mist system is not really ideal due to the presence of electricity,” van Niekerk explains. “You want to ensure you are putting in a suppression medium that is not going to create more damage than the fire itself.” In terms of gas fire-suppression systems, there are two main..., 23 Jun 2017 08:47:40 GMTCreating a virtuous cycle for miningMining may not dominate the economic landscape as it once did, still it remains a tremendously significant player. The mining industry accounts for 20% of all investment in the country and generates R 441 billion in expenditure annually, of which R 407 billion is spent locally. Despite its importance, the mining sector is facing severe pressure on various fronts, including costs, environmental liability, ant the lack of a cohesive strategy in terms of minerals demanded by the future green economy. Converting these challenges into opportunities is the theme of the Sustainability and Mining Seminar at Sustainability Week 2017, taking place 14 June at the CSIR International Convention Centre, Tshwane. Tshego Motsoenyane, Chief Operating Officer at Ncamiso Mining and a speaker at the Sustainability in Mining Seminar taking place during Sustainability Week 2017, spells out the challenges of the present: “On a global front, mining operations face severe economic and..., 09 Jun 2017 09:30:36 GMTEM continues to supply the best products at the right priceWith virtually every panel builder in South Africa using ubiquitous technology distributed exclusively by ElectroMechanica (EM), the major supplier continues to build on its strategy of providing the right product at the right price, for the correct application and specification at hand. This strategy has stood the company in good stead since it was established in 1984 by CEO Dave van den Berg. Finder plug-in relays and PC board mounting relays and Lovato connectors, manual motor starters, and motor control switchgear were its first major breakthrough agencies in the local market. EM still distributes these brands today, and is the oldest distributor globally for both these international leaders. “When we started with Lovato, it had a limited range of contactors. It has grown tremendously since then, and now has one of the broadest product ranges in the market,” van den Berg comments.
