Stand-alone Equipment

Based on our long-standing experience and achievements as an engineering company, we offer a wide range of equipment that constitutes various plants, including heating furnaces and pressure vessels.

Stand-alone Equipment

  • Heating Furnace

    We have numerous achievements in installing new heating furnaces (such as VC furnaces, BOX furnaces, etc.), used for heating fluids in oil refining, petrochemicals, and similar fields. We also have extensive experience in providing EPC (Engineering, Procurement, and Construction) services for energy-saving and fuel conversion of existing heating furnaces, including those manufactured by other companies.

  • Pressure Vessels

    We have numerous accomplishments in the design and manufacture of tower-type vessels (reactors, towers, tanks, cone roof tanks, etc.), and various types of heat exchangers. In addition, we also perform seismic design based on various laws, standards, and criteria.

  • HTS Reactor

    HTS (inorganic molten salt heat medium, commonly known as 'Niter'), traditionally challenging to handle due to its high melting point of 142°C, has seen its drawbacks overcome through our 'water dilution technology,' resulting in numerous installations. Our company possesses extensive know-how regarding HTS, enabling us to handle everything from the design and manufacture of the equipment to operational guidance.
    High-Temperature HTS Heat Medium Equipment Operating temperature range: 300-550°C

Sulfuric Acid Stand-Alone Equipment

  • Sulfuric Acid Plant

    We have numerous achievements in updating stand-alone equipment such as devices, piping materials, humidifying towers, drying towers, and preheaters, using corrosion-resistant materials like SX and ZeCor
