Semac Consultants Limited, originally established as Revathi Equipment Pvt. Ltd. in 1977, has undergone several transformations and name changes, most recently in July 2023. The company specializes in engineering and procurement contracting (EPC) and offers a range of services in general, mechanical, process, and civil engineering. Its capabilities extend to design, architectural structuring, MEP, interiors, and warehousing solutions.
Over the years, Semac has expanded its manufacturing operations, initially in collaboration with Chicago Pneumatic Tool Company, USA, to produce drilling equipment. The company has developed a variety of drilling solutions, including water well rigs, blast hole rigs, and high-performance DTH hammers, and has expanded into renewable energy with wind power installations. Through strategic mergers and acquisitions, including a significant reorganization in 2022-23, the company absorbed various businesses while divesting others, positioning itself as a comprehensive engineering services provider in the industry.
