The COOLstar® burner is an advanced
solution for extremely compact, ultra-low
NOx gas firing applications. Thousands of
COOLstar burners are in service today
because of its proven results.
The COOLstar burner applies John Zink’s
proprietary flue-gas entrainment and mixing
strategy using the energy of incoming
fuel and air streams. This results in stable,
compact flames and NOx guarantees as low
as 15 ppmvd (31 mg/Nm3).
John Zink engineers developed the COOLstar
burner from the customer’s point of view
with a focus on safety, easy operation and
optimum performance. Its compact design
makes it well suited for retrofit applications.
The COOLstar burner requires minimal
maintenance and operates with a wide
range of fuels, setting a high standard for
economical, ultra-low NOx combustion.
John Zink Company is a world leader in
clean combustion technologies and
environmental systems, focused on solutions
for your operations.
