Description
The Lennox 57W85 Heat Exchanger is useful in the operation of a gas furnace and is used to transfer heat from the combustion gases to air moving in the HVAC system. Made from heat resistant material, heat exchanger used in this project provide efficient heat transfer and conserve heat energy. It operates by directing hot gasses in a number of pipes where heat from the gasses is taken and exchanged with the air that is to be circulated within a given building. This component is particularly applied in Lennox gas furnaces, to provide optimum heating and efficiency.
