WNS Series Fuel Gas Condensing Steam Boiler - 3-Pass Wet Back Design with 100%+ Thermal Efficiency

The WNS Series condensing steam boiler utilizes advanced 3-pass wet back design technology for optimal heat transfer efficiency. This automated boiler system features a wave furnace design where radiant heat transfers through the furnace walls during the first pass. High-temperature combustion gases converge in the reburning chamber for the second pass through the spiral tube bundle area, then proceed to the third pass through the light tube bundle area before exhausting through the chimney.
