VIEW DATA SHEET

2ppm NOx at 3% Excess O₂

Maximum fuel efficiency with minimal NOx. Achieve 2ppm NOx when operating with 3% stack oxygen or lower.

Easily Retrofittable

Uses industry standard fuel pressure, air pressure, and controls. No need for a new fan or sensors.

More Efficient Operation

By operating with lower excess oxygen, you can save money even while reducing emissions.

No CO Emissions

Under normal operation in most fired equipment CO emissions are zero.

Robust Design

No metal mesh, no ceramics, and no refractory block means no fouling and rapid light-off and turndown.

Short Flames

Flames that terminate near the burner mounting location help ensure that your fired equipment operates as designed.
