Linnox ULE (Ultra Low Emissions) burners deliver ultra low emissions and uniform heat.

The Honeywell Eclipse Linnox ULE burner is designed for use in any direct or indirect fired air heating application requiring state-of-the-art burner technology. Where excellent heat distribution, temperature uniformity, best in class low emissions, and simple robust controls are the decision points in product selection and specification, the Linnox ULE is the industry standard.

This burner operation is based on a high excess air pre-mix combustion that keeps flame temperatures low while burner geometry establishes an internal recirculation flame pattern. This allows for very low emissions at a high turndown rate (10:1) while maintaining extremely stable combustion. Specifically, the emissions in the undiluted flue gasses are less than 15 ppm NOx at nominal input, establishing the Linnox burner as the lowest NOx burner of its kind.
