This heavy-duty Lennox heat exchanger is a critical replacement component for commercial gas-fired rooftop units (RTUs). Designed to facilitate high-efficiency thermal transfer, it ensures that the combustion process remains safely contained while effectively heating the air distributed throughout your building. Constructed from durable, corrosion-resistant materials, this heat exchanger is engineered to withstand the extreme temperature fluctuations and environmental demands of rooftop HVAC applications. Replacing a cracked or compromised heat exchanger is essential for maintaining indoor air quality, ensuring system safety, and restoring the energy efficiency of your commercial heating system.
Type: HVAC Heat Exchanger
Size: Large
Application: Used in commercial gas heating systems, packaged rooftop units (RTUs), and industrial HVAC air handling systems to transfer heat from combustion gases to the air supply.
Specifications: High-thermal conductivity metal construction, corrosion-resistant finish, precision-engineered airflow passages, and safety-certified weld points.
