Test FacilityHoneywell UOP Callidus test facilities
in the U.S. and China are used for
combustion technology research and
development, as well as for customer
demonstrations. Our array of test
systems allow us to closely match actual
field operating conditions, providing
results that will more accurately predict
actual measured performance.
Global CoverageHoneywell UOP Callidus reaches the
global market through our headquarters
located in Tulsa, Oklahoma, USA, with
regional direct sales offices and
independent sales representation
around the world. Meeting our
customers’ expectations and setting
the standards for the combustion
industry have always been our goals.
Each burner, flare, thermal oxidizer
and catalyst system we design and
manufacture is built with those goals
in mind.
