Three red-and-graphite Atmos boilers line up at the front of the stand, the middle one with its loading door open to show the firebox. Behind them a white tower with the Atmos logo rises above photo panels of snowy log piles, and a card for the "DC25GD" wood gasification boiler lists "25 kW" and "DREWNO" as fuel.
