Duratherm^TM

Low NOx Gas-Fired Radiant Gas Burners for High Performance Residential and Commercial Heaters and Boilers

GAS-FIRED RADIANT BURNER
Alzeta’s DURATHERM burner is a forced-draft, pre-mixed, gas-fired radiant burner designed for use in residential, commercial and industrial heating equipment requiring efficient, high intensity, transfer of heat with state-of-the-art emissions performance.

The DURATHERM burner is available in cylindrical configurations in just about any cross-sectional shape to match the heat delivery needs of most heating devices. With small capacity burners, the burner element is usually supplied in a single piece design. For larger capacities (above 1,500,000 Btu/hr), the burner element is usually assembled from multiple cylindrical segments to facilitate handling and installation.
