Condensing high efficiency once-through steam boiler
KDKE-HE Series
Feature
  • Equipped with a high-performance water supply pre-heater (STS-304/316), it absorbs the high-temperature exhaust gas’s heat generated after combustion as much as possible, and increases the water inlet temperature to achieve more than 99% efficiency.
  • As the conductivity of boiler water is maintained within the allowable value by automatically measuring the concentration of boiler water, there is no carry-over and the lifespan is extended.
  • Compact body design reduces the volume of retained water and allows steam to be generated quickly within 3~5 minutes after burner ignition.
  • Easy to handle as operation, water supply and burner combustion control can be automatically controlled and set with one-touch operation
  • Equipped with a high-performance steam separator to supply high-quality dry steam even with sudden load fluctuations.
  • Attaching a low-NOx burner ensures fuel cost saving, and NOx of 40 ppm or less is guaranteed for operation under 4% of O₂. (Option)
  • The artificial intelligence D-Brain control enables easier operation and management. (Option)
