THE HELIFLOW® HEAT EXCHANGERࢳ
About Us
Graham Corporation is a global
leader in the design and manufacture
of mission-critical fluid, power, heat
transfer, and vacuum technologies
for the defense, space, energy, and
process industries.
The Graham Manufacturing Team is
driven to deliver superior vacuum
and heat transfer solutions for a safe,
energy-efficient,
and
sustainable
future by building a dynamic compa-
ny through continuous investment in
our people, processes, and technolo-
gy.
NOT YOUR ORDINARY SPIRAL
HEAT EXCHANGER
• up to 1,000 bar (15,000 PSIG).
• 100% effective surface area.
• Up to 40% more efficient than
straight
shell
and
tube
heat
exchangers.
The unique design of the heliflow
encompasses a spiral coil mounted
within a casing and baseplate.
The Heliflow design is ideal for
high-pressure and high-temperature
heat
transfer
applications. The
spiral tube bundle eliminates the
thermal
expansion
issues
that
plague shell and tube heat exchang-
ers because the tube bundle is
allowed to expand and contract, the
thermal stress on the material and
the welded joints of the bundle is
minimized. This allows for extend-
ed unit life even under the demand-
ing service of high-pressure appli-
cations.
ELIMINATES:
• The need for expansion joints.
• Concerns of thermal expansion
and shock.
• High priced water boxes and chan-
nels.
• Gaskets on the tubeside.
