- National Oxygen Limited (NOL.BO), founded in 1974 and headquartered in Chennai, Tamil Nadu, India, manufactures and supplies industrial gases in liquid and gaseous forms primarily to industries, hospitals, government workshops, public sector units, steel, pharmaceutical, petrochemical, refrigeration, shipbuilding, fabrication, space, and marine sectors across India. The company produces liquid and gaseous oxygen, liquid and gaseous nitrogen, medical-grade oxygen (liquid and gas), high-purity nitrogen gas, industrial argon gas, and dissolved acetylene gas; its production capacity includes 2500 cubic meters per hour of oxygen and nitrogen gases from facilities in Pondicherry and Tamil Nadu, plus 200,000 cubic meters per annum of dissolved acetylene. Manufacturing operations feature air separation units, including a 55 TPD ASU commissioned in 2013 at SIPCOT Perundurai, Erode District, Tamil Nadu, complemented by a 1.65 MW windmill installed in 2005 at Dhule, Maharashtra, for energy support. NOL maintains group affiliations with ECA Gases LLP for acetylene production, Pondicherry Agro Foods Pvt. Ltd. for flour and spice milling, and Saraf Housing Development Pvt. Ltd. for real estate. Recent financial performance reflects challenges, with net sales declining to Rs 40.58 crore for the year ended March 2025 (down 10.34% year-over-year) and quarterly net losses reported through September 2025 amid reduced demand; no major acquisitions, partnerships, funding rounds, or new product launches have been announced in 2024 or 2025, maintaining focus on core gas production and supply operations.
