A revolutionary burner system for straight through radiant tubes.
The RASERT single-ended, radiant tube burner system reverses conventional
thinking about firing straight radiant tubes. Unlike traditional single-ended radiant
tubes (SERTs) the RASERT
ERT initiates combustion in the annulus formed between the
radiant tube and the return
urn tube within. Developed with the assistance of the Gas
Technology Institute, this
his patented Reverse Annulus Single-Ended Radiant Tube
firing method results in distinctive advantages for the user, whether converting an
existing system or designing
gning new.

Extends Radiant Tube Life
High and volatile alloy prices, labor and extended downtime
add up to make replacing radiant tubes a costly process.
RASERT's lower center tube temperature and uniform outer
tube temperature maximize radiant tube life by eliminating
stress-inducing "hot spots" while keeping tube material
temperatures at a minimum.
Highly Efficient Combustion
RASERT's high efficiency and heat transfer result in fuel
savings of up to 50%, reducing the impact of fuel price
variations on your bottom line.

RASERT Fuel Savings
Easy to Retrofit
Downtime adds significant costs to existing equipment
upgrades. The RASERT focuses on a compact package for "fast
fits" to many existing radiant tubes. A suite of accessories is
available for easy conversion of your tubes.
Fuel savings based on converting a cold air burner
system with continuous operation at 75% of rated
capacity for 8,000 hours per year.

Low Emissions
Whether you are facing stringent NOx emissions or looking for
reduction in greenhouse gases, the RASERT system meets the
challenge. NOx emissions are reduced by a combination of
cool annular flames, staged combustion and internal flue gas
recirculation. High efficiency combustion also reduces the
generation of CO 2, a targeted greenhouse gas.
High Output
RASERT's lower center tube temperature and quick annular
heat release allow for increased thermal input. This increased
input typically results in proportionate increases in production
rate.
