Cochran; 135 Years of World-Beating Energy Solutions Steam Generation are the exclusive southern Africa agents for world-famous British boiler and associated equipment manufacturers, Cochran. Established in 1878, Cochran were actually the original inventors of the revolutionary horizontal firetube boiler. The Thompson-Cochran group later brought modern package boiler technology to South Africa, and as part of Rolls-Royce, Cochran became a leading international boilermaker. Since regaining its independence as a company, Cochran has continued to develop its global business and is now proud to re-enter the South African market in association with respected African heat technology company, Steam Generation.

The new Scottish-South African partnership will supply Cochran’s famous Borderer, Wee Chieftain, Thermax and Coalmaster boilers to the region, supported by expert installation and maintenance services delivered by Cochran’s trusted South African partner, Steam Generation.

Cochran are also a global leader in Heat Recovery Boilers. Operated in conjunction with a wide range of industrial engines and processes, they generate ‘free’ hot water or steam using previously wasted exhaust or process-generated heat. Often paying for themselves in just a few months, Heat Recovery Boilers reduce waste and total energy costs, whilst also cutting overall carbon emissions.

We drive heavy industry

The new SEW girth gear – flexible concepts for diverse combinations Girth gears - the latest offering in our industrial gear range - are used to drive large, rotating systems such as dryers, rotary kilns or horizontal mills. Traditional girth gears generally consist of two to four segments that are assembled together for processing. In contrast, SEW-EURODRIVE girth gears are split into several identical segments in order to keep the component parts short and easy to handle.

We deliver not only girth gears, but the entire drive package!

Main advantages: ∙ Guarantee flawless casting quality on critical areas ∙ Individual segments of girth rings are interchangeable ∙ Only damaged individual parts need to be replaced instead of changing the whole ring ∙ Handling of each individual segment is easier ∙ Segmented design enables easy and cost-efficient transportation
