DuralokPlus® Primary Heat Exchanger
The
Heart of the 3Dimension furnace operates by burning the fuel
inside the exchanger that warms the air traveling across the outside of
the heat exchanger. Made of high-quality patented ArmorTuf alumanized
steel, its patented crimped seam is a Lennox® exclusive feature designed
to provide longer life and safer operations.
Secondary Heat Exchanger Allows
the furnace to reach higher efficiency levels by capturing every last bit
of available heat and is made of rugged 29-4C stainless steel for corrosion
resistance.
