Howden says it has won a contract to supply a cooling system for the expansion of OZ Minerals’ Prominent Hill mine in South Australia.
The solution provided by Howden will be for the complete mine cooling system, with Howden’s equipment ensuring safe productive outcomes at depth and additional efficiencies to reduce environmental impact for current and future carbon footprint compliance.
Howden will focus on sustainability and the solution will include closed circuitry on both condenser and evaporator circuits and R717 (Ammonia) compressors which emit no harmful CO2 or HFCs, the company said. The system consumes no water, using the ambient air as the cooling medium and Howden will supply chillers, air cooled condensers, bulk air coolers, pumps, electronic controls and hydraulic design.
Camille Levy, President of Howden APAC, said: “Howden works in partnership with customers to create solutions for their needs which are of the highest functionality, while supporting their net zero targets. This project is no exception. Our unique combination of manufacturing excellence, technical and project deliverables, and our global experience, also contributes to the reduction of carbon impact of operations.”
The use of Howden refrigeration screw compressor technology coupled with supplies of condenser coolers and bulk air coolers were other supporting factors in the successful offer which will be delivered by the Howden team in China, the company said.
The OZ Minerals Board approved construction of a hoisting shaft at the Prominent Hill copper-gold mine in South Australia last year, paving the way for a mine life extension and throughput expansion.
