BHI

BHI designs, manufactures, and installs equipment used in power plants, including industrial boilers, heat-recovery steam generators (which capture exhaust heat from gas turbines to produce additional electricity), condensers, heat exchangers, and deaerators.

Listed on KOSDAQ, Korea's tech and small-cap exchange, it supplies power utilities, large construction firms, and steelmakers. The single largest share of its revenue comes from heat-recovery steam generators used in combined-cycle and cogeneration power plants, and every product is made to order rather than held as standard inventory.
