  • The Heating Coil is one of the most important equipment on vessels, installed at the bottom of the fuel tank.

    It maintains the internal temperature of the fuel tank at a constant level using steam inside the drum, which helps preserve the fuel's viscosity.

    This Heating Coil is used in F.O. Tanks, Cargo Tanks on Crude Oil Tankers (COT) and Product Chemical Tankers (PCT), NaOH Tanks, and L.O. Tanks. Steam, thermal oil, or warm water flows through the Heating Coil to maintain or heat the temperature of the fuel.

    We at Samkun Century Co., Ltd. manufacture this Heating Coil using high-quality technology and rigorous inspection, supplying them to various shipyards. In particular, our Drum Type and Spring Type Heating Coils are representative products, holding over a 90% market share in Korea.



  • The Heating medium (e.g., Steam) flows to the drum shell through pipes, and the heat is transferred to the Pin tubes. This Heat facilitates convection, which is the main factor in heating the fuels in the tank. This Drum type Heating Coil can be installed in small and narrow tanks by connecting each drum.

  • The Heating medium (e.g., Steam) from the boiler heats the fuel through pipes. Place the pipe by connecting it with a sleeve fitting, and depending on the volume of the Oil Tank, the pipe lines can be arranged flexibly.



  • The Spring Type (Circle) Heating Coil has a similar concept to the Bare Type, but it is more efficient for space utilization.
