Direct Gas Heater
A direct-fired industrial gas heater developed through a technology partnership between NBPKOREA and MIDCO International (USA). The flame from the combustion burner directly contacts the air, enabling rapid heating of large spaces — widely used in shipyard block workshops, warehouses, paint booths, and more.
Available in 5 models ranging from 250,000 to 1,000,000 Kcal/h, compatible with LNG, LPG, and city gas, with modulating control for precise temperature management. Both portable and fixed installation options are supported.
