Trane EXC01323 400 MBH Gas Heat Exchanger Assembly

The Trane EXC01323 Gas Heat Exchanger Assembly is a core thermal transfer component used in compatible furnace systems. It transfers heat generated by gas combustion to the surrounding air stream without allowing direct contact between combustion-circulated air. Rated for 400 MBH capacity, it is built to handle high heat output levels during continuous operation. In HVAC systems, it is installed within the furnace combustion section where it absorbs and transfers thermal energy during firing cycles, supporting efficient heat delivery and consistent temperature rise across the air distribution system during heating operation.
