The Lennox 99W42 5-Tube Heat Exchanger (108K BTUH Aluminum) is a critical heating component designed to transfer heat within gas-fired HVAC systems. Installed inside furnaces or packaged rooftop units, it channels hot combustion gases through five aluminum tubes, allowing heat to pass through the exchanger walls while a blower circulates warm air into the duct system. This design safely separates combustion gases from breathable air. Commonly used in Lennox packaged heating units and air handling systems, it provides efficient heat transfer, improved energy performance, reliable operation, and long-lasting durability in commercial and residential HVAC applications.
For an efficient and reliable HVAC system, the Lennox 5-Tube Heat Exchanger 108K BTUH Aluminum is a great choice for optimal system performance.
