LENNOX 99W43 HEAT EXCHANGER

HEAT EXCHANGER

The Lennox Heat Exchanger is the component that makes it all possible - transforming energy into comfort. The secret behind its success is its twin-pass, non-circulating design. Flammable refrigerants travel through one side of the heat exchanger; air passes through the other. This superior design results in more efficient heating and cooling, a smaller package, less condensing surface area and a faster startup time.

The Lennox 99W43 Heat Exchanger is a compatible replacement for the following systems:

The Lennox 99W43 heat exchanger is designed for air distribution in existing forced air systems. This heat exchanger transfers heat from warm outside air to return air. It is designed to increase the efficiency of heating and cooling systems and consists of a finned aluminum core and chrome-plated steel shell, which are securely bonded together with epoxy. It has flexible copper tube legs that can be easily bent to fit almost any ductwork system up to 23 feet in length. The 99W43 heat exchanger is manufactured by Lennox, a trusted name in heating and cooling products.

Lennox Heat Exchangers are solid brass, pressure tested, and designed to withstand the everyday rigors of the HVAC industry. With a 100% gasket-to-shell joint and a 3/4" thick copper fin layer, these heat exchangers are engineered to provide extended life for residential heating systems.

A Lennox® heat exchanger is installed in your furnace to help distribute heat more uniformly and efficiently. Its open-flow design boosts efficiency by replacing lost heat from the exhaust gases with fresh, pre-heated air circulating throughout the home.

Maximize your heating, cooling and hot water production. Our Lennox heat exchangers are designed to deliver optimum thermal efficiency for your commercial HVACR application. For greater heating efficiency, the 99W43 heat exchanger employs a spiral fin design with variable fin pitch control and adjustable hinges on all four sides. And our patented Easy-Sump sloped subbase design—ensuring our exchangers deliver optimum efficiency.
