Business Areas

• Power Generation and Plant Auxiliary Equipment Engineering: We custom-design and manufacture auxiliary equipment for major machinery and piping systems used in nuclear power plants, thermal power plants, and chemical plants. Based on flow analysis and structural analysis, we supply equipment that helps optimize the operation of generator and turbine systems.
• Piping Support Manufacturing: We manufacture special pipe hangers and support systems that absorb and mitigate thermal expansion and load changes in pipes. In particular, we possess cold support technology essential for LNG carriers, liquefaction bases, and cryogenic gas pipelines.

Products

• CTCS and Debris Filter (Condenser Cleaning System and Filter): This is a CTCS (Condenser Tube Cleaning System) that automatically cleans foreign substances inside power plant condenser tubes, and a filtration device that filters foreign substances from water intake facilities. It maximizes thermal efficiency and stably supports continuous power generation operations.
• Turbine/Generator Auxiliary Equipment (Lube Oil & Water Cooling System): This is a system that stably supplies lubricating oil to turbine shafts operated by high-pressure steam and a water cooling facility that controls high heat. It prevents internal gas leakage and equipment overheating, thereby extending the lifespan of plant equipment.
• Cryogenic Pipe Support (Cold Support): This is a special insulation support that prevents cold energy loss and firmly supports pipes in LNG storage tanks and cryogenic fluid transfer lines. It is widely supplied to domestic and international plants due to its high insulation performance and load-bearing capacity.

Special Notes

• Domestic and International Market Share and Proven References: The company holds a dominant domestic market share in the fields of condenser cleaning systems and cryogenic pipe supports. It has a strong track record of exports to overseas power plant projects in Japan, the Middle East, and Europe, as well as to major domestic heavy industry companies and Korea Hydro & Nuclear Power.
• Consistent Quality Certification System from Design to Processing: It possesses a strict engineering system that meets quality standards related to nuclear power and high-pressure gas. Through continuous R&D investment and dozens of intellectual property rights, its plant-customized manufacturing capabilities are widely recognized.
