Klass Company, by acquiring technical knowledge and technology transfer from SC Engineering of South Korea, which is on the vendor list of the National Iranian Oil Engineering Company, has established an engineering group and gathered renowned national experts. It is now a leader in the design and supply of various types of water tube boilers, HRSG (Heat Recovery Steam Generators), waste incinerator boilers, and WHRB units.
Currently, with the aim of research and development and synergy of experiences, the design and engineering group of SG1TECH has merged with the engineering unit of Klass Company. With access to the latest design software, it is capable of designing various sizes and capacities of water tube boilers for both power plants and industrial applications. In the list of activities of the specialists in this group, there is a wide range of units for various gas turbine models from different brands, including H25, Zoriya, SIEMENS SGT-400, SIEMENS SGT-600, MAPNA MGT-40, GE-F5, GE-F6, and others.
Given the strong and specialized presence of this company in the boiler market in Iran and the surrounding countries, along with a comprehensive understanding of domestic production capacities and evaluations conducted among reputable and committed local manufacturers, this company, in collaboration with well-known and reputable domestic and foreign manufacturers with a successful track record in national projects in the oil, gas, petrochemical, and power industries, is capable of producing high-pressure components such as boiler accessories, drums, headers, piping systems, and other equipment. Therefore, Klass Company, through a partnership, can play a significant role in EPC projects by providing design and engineering services, project management, and coordination among consortium members, all while adhering to the highest international standards.
Notable achievements in this field include the design and construction of a 120-ton per hour water tube boiler for the Bidboland Persian Gulf Gas Refinery, a 120-ton per hour boiler for Zarand Iranian Steel Company, HRSG (Heat Recovery Steam Generator) boilers for the Shiraz Petrochemical Utility Complex (3 units), Bushehr Petrochemical (1 unit), Abadan Oil Refinery (5 units), Tabriz Oil Refinery (2 units), Tehran Oil Refinery (4 units), and several other projects.
Furthermore, this company, through collaboration and obtaining multiple representational agreements with reputable European, Japanese, and South Korean manufacturers, now possesses the latest technical knowledge and technology in providing design, engineering, and supply services for other equipment. This includes Steam Turbines, main and auxiliary components for various gas turbines and their associated generators, industrial water treatment systems, drinking water systems, various pumps, boiler feed water systems, industrial valves, and other related components in utilities. These companies are listed in the approved manufacturers’ list of the National Oil Company, the Ministry of Energy, and MAPNA Group.
In general, this company, by bringing together experienced and committed domestic and foreign specialists in the field of boiler design and power plant engineering, is capable of providing high-quality services in the design and construction of power plants. And in the management of equipment construction, it is capable of providing the following services:
