• ThermJet Self-Recuperative Burner

    The Eclipse TJSR V5 is a direct fired, self-recuperative burner based on our industry proven ThermJet technology. This advanced burner design combines a high velocity flame with fuel saving recuperation. A space saving, integral eductor pulls the furnace exhaust through an internal ceramic recuperator. The recuperator preheats the incoming combustion air to very high levels, which improves furnace operating efficiency to reduce fuel usage by as much as 50% over typical ambient air burners.

    The TJSR V5 design eliminates the need for hot air ductwork required by external recuperators, providing savings in hardware and installation. The internally insulated heat exchanger section and exhaust housing hold heat in the recuperative section, adding to the heat recovery efficiency.

    • The integrated gas and air orifices simplify burner piping, set-up and adjustment. There is no guesswork with input levels or burner capacity settings at startup.
    • The new burner housing design is up to 40% lighter, making furnace structural changes and installation simpler, with no fear of high stress mounting areas.
    • Internal components are made of space age silicon carbide materials, built to deliver excellent heat transfer and extremely long burner life.
    • Installation, operation, and maintenance are simplified and less costly. And the fuel savings are constant, with no deg- radation of the exchanger/recuperator section, even after years of use.
    • TJSR V5 can be fired on natural gas, propane or butane.
