UniflUx/ExothErm
Exotherm Corporation is a leader in providing custom designed
fired heaters to the chemical processing and oil and gas
processing industries.

Exotherm's Uniflux
Convection Heater was
developed fifty years
ago to overcome the
problems of overheating
and degrading heat
sensitive process fluids
that customers experienced with their existing fired heaters.
The Uniflux Convection Heater is custom designed for processes
requiring 100,000 to 70,000,000 Btu/hr absorbed duty. The heater
is designed to utilize the circulation of high velocity exhaust gases
around the process tubes to produce convective heat transfer. This
heat transfer is uniform around the periphery of the process tubes.
The result is lower tube wall and film temperatures compared with
the radiant heat transfer method used in most heaters.
no flAmE imPinGEmEnt
The high velocity Uniflux burner has a very short flame extension,
preventing flame impingement on the process tubes. This in turn
reduces tube failure and coking.
EffiCiEnCY
The forced draft burner operates at very low excess air. This
feature allows the Uniflux Convection Heater to operate at higher
efficiencies than can be achieved with conventional radiant,
natural draft heaters. Uniflux Convection Heaters equipped
with process pre-heat economizers can achieve efficiencies as
high as 95% for some
processes, and the
forced draft design
allows the Uniflux
heater to maintain the
efficiency over the entire
operating range.
tUrnDoWn
The normal turndown ratio of the Uniflux Convection Heater is
10:1. Turndown ratios
of 40:1 can be achieved
with custom designed
burner controls.

rEliABilitY
Each Uniflux Convection
Heater is equipped with a field proven burner management system
and safety controls. The heater and
all of its controls are completely shop assembled. The control
system is tested at the factory to ensure safe and reliable
operation when installed.
loWEr inStAllAtion CoStS
The Uniflux Convection Heater is designed as a package and is
completely assembled at the factory. Smaller heaters are shipped
as a complete package. Larger heaters are disassembled into three
major components. This makes installation easy and less costly.
fiElD SErViCE
Qualified, experienced technicians are available to assist
the customer with start-up, operator training, preventative
maintenance programs and trouble shooting.
APPliCAtionS
