Callidus Burners

AERO Radiant Wall Burners

Prevent dangerous hydrogen flashback with an innovative tip design


Fluctuating hydrogen content can cause dangerous flashbacks, often due to a design feature of traditional tips. When you have varying hydrogen (up to 80%), the AERO Radiant Wall burner is an ideal choice.  The innovative tip, combined with Venturi airflow mixing design, removes the requirement to adjust based on gas composition.

Callidus AERO Radiant Wall Burners provide a combination of high performance and low maintenance for new or existing wall-fired petrochemical and reformer furnaces.
