Company Description
Hamilton Research & Technology Private Limited (HART) is a technology company specializing in retrofit solutions for aluminum smelters, combining deep process domain expertise with AI to drive self-reliance, profitability, and sustainability for its clients. As a subsidiary of S&S; Power, HART draws on global engineering and technology capability to deliver smart pot controllers, advanced heat regulation systems, superheat measurement solutions, and customized hardware and software services.
HART's core value proposition is process efficiency that translates directly into client financial performance — plants running HART systems and healthy operating practices, consistently operate above the global average pot efficiency of 94%, with energy consumption often reduced to 12,900–13,500 units per ton of aluminum produced, ahead of industry norms. A hands-on team of in-house engineers works closely with clients to convert proprietary "black-box" control systems into configurable, transparent "open-box" solutions,



backed by compatible spares and modules that extend equipment life.
At its core, HART is driven by a simple belief: the aluminum industry doesn't have to choose between profitability and the planet. Every retrofit, every efficiency gain, and every unit of energy saved is a step toward a lower-carbon future for one of the world's most energy-intensive industries — and we're looking for people who want their work to count toward that.
