903420 RG1D90 Series Furnace Heat Exchanger

The Nordyne 903420 Heat Exchanger is an essential component in certain gas furnaces, gas-powered combination furnaces, and air conditioners. It is a large-surface-area metal coil that effectively moves heat from the combustion process into the air stream. During operation, heated flue gases pass through the heat exchanger tubes while a separate air stream runs over the outer fins. By transferring heat from the hot gasses to the cooler air, this system warms the air that is distributed throughout the house.The Nordyne 903420 Heat Exchanger is well-known for its long-lasting sturdiness and effective heat transmission, which help to improve furnace dependability and energy efficiency.
