This study evaluates the cooling system of ZH9000 air compressors in an alumina refinery, addressing overheating and energy inefficiency. The proposed solution involves plate heat exchangers to isolate the water circuit, minimizing contamination and enhancing thermal performance. Findings suggest annual savings of R$600,000 and lower maintenance costs, with a 10-month payback period.
