Air Eliminators for the Common Seawater Supply Project in Basrah, Iraq, ordered after technical clearance Vadodara, 04 November 2026: Cryogenic OGS Limited (BSE SME: 544440), a manufacturer of metering, filtration and process equipment for the oil and gas industry, has received a Supply Contract from Hyundai Engineering & Construction Co., Ltd. (“Hyundai E&C”) of the Republic of Korea. The contract covers the design, engineering, manufacturing, testing and delivery of Air Eliminators for the Common Seawater Supply Project in Basrah, Iraq. Order details. The contract is valued at USD 35,700 (approximately ₹33.8 lakh), excluding VAT. It covers multiple sets of Air Eliminators with flame arrestors, ASME Code stamping and commissioning spares. Delivery is due by 30th June, 2027 on FOB international port terms. Technical clearance. Hyundai E&C approached Cryogenic OGS for its products, and the order was placed after the Company’s offer was technically cleared. A first for the Company. This is Cryogenic OGS’s first order for ASME “U” stamped equipment. The “U” stamp is the ASME mark for pressure vessels built to Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code. While the value of the order is modest, it gives the Company a reference with an international EPC contractor for code-stamped equipment. Commenting on the order, Mr. Nilesh Patel, Chairman and Managing Director, said: “For a company of Hyundai E&C’s standing to come to us is a proud moment for our team. We went through a rigorous process, meeting stringent technical requirements and conditions before we were approved and in a position to win this order. This is also our first ASME ‘U’ stamp order, and it shows that our engineering and quality systems can meet the requirements of prestigious global EPC companies.” About Cryogenic OGS Limited Incorporated in 1997 and based in Vadodara, Gujarat, Cryogenic OGS Limited provides equipment solutions for metering, filtering, pressure reduction, dosing and blending.
