Honeywell Eclipse ThermJet or TJ direct fire burners feature the highest flame velocities available.

The industry standard for velocity burners, the low NOx ThermJet represents a technological leap forward in every area of design and performance. Comparison tests show that ThermJet delivers the lowest emissions of any competitive model. Integrated gas and air orifices simplify burner piping, set-up and adjustment. Air and gas inlets are independently adjustable in 90-degree increments to suit a variety of piping alternatives.

The burners are available in 14 sizes with maximum capacities ranging from 150,000 to 20,000,000 Btu/hr. All models are also available for use with preheated combustion air. Installation, operation and maintenance are simple and cost effective. Eclipse ThermJet direct fire burners are made to last – with rugged Eclipse dependability and reliability built in.


Typical applications include: tempering furnaces, hardening furnaces, reheating furnaces, fluidized bed driers, thermal oxidizers, non-ferrous melting, ladle/tundish, glass lehrs, environmental applications, and preheated air.
