History
XLG was established in 2005 by engineers
that accumulate broad experience in heat
transfer after many years working in different
companies manufacturing CTHE Corrugated
Tube Heat Exchangers.
XLG expertise allows us to design and
fabricate our state-of-the-art XTube® range of
CTHE, an improved and reliable array of heat
exchangers very suitable for applications in
Environmental Control, Chemical Industry, Food
& Dairy, Automotive, Shipbuilding, Power and
others.
Monotubes-Multitube-Tripletubes
Monotubes-Multitube-Tripletubes XTube® CTHE's are designed and
fabricated to suit sanitary and non- sanitary applications.
￭ If the process is sanitary all product side surfaces are polished to
ensure a surface roughness Ra ≤ 0.8 μm. And the connections are
those typical in the food, dairy and beverage industries.
￭ Special care if taken when pharmaceutical processes are involved as
the surface roughness demanded has lower values 0.25-0.4 μm (by
electropolishing),
seamless tubes and special sterile flanges or clamps.
￭ When non-sanitary conditions surface roughness is not an issue but
high mechanical resistance, high temperatures and pressures, and
corrosive.
Product Range
XLG range of XTube® Corrugated Tube Heat Exchanger if formed by three families of models.
￭ Monotube
geometry that is formed
by tube-in-tube models.
￭ Multitube
geometry with a tube bundle
inside a shell.
￭ Tripletube
geometry formed by 3 or 4 tubes to form
an annular space. Three geometries to process
a vast type of products from low to averange and
viscous products, also with particles or solids
in suspension like fibers, dices etc.
Monotube
Xtube® Monotube is used to process products under sanitary
and non-sanitary conditions:
￭ Fluids
with solids in suspension from small to big size
(corrugated tubes can be up to 210 mm in diameter).
￭ Particulated
products (products in pieces).
Multitube
Xtube® with Multitube geometry can be used sanitary and
non- sanitary applications. There are 3 families of
multitubes:
￭ XTube®
B-Type for Industrial Applications (non-sanitary).
￭ XTube®
Multitube for sanitary applications in the Food,
Dairy etc industries. Product side surfaces are polished to
ensure a surface roughness Ra ≤ 0.8 μm.
￭ XTube®
Pharmagrade for pharmaceutical and biotech.
Product side surfaces are polished to get a surface
roughness Ra ≤ 0.25-0.4 μm.
XTube® B-Type
Xtube® B-Type is used
to process products
under non-sanitary
conditions:
￭ Low (water) viscosity
and average viscosity
fluids (latex).
￭ Slurries that include
small solids in
suspension up to 5 mm.
Xtube® Multitube
Xtube® Multitube is
used to process
products under
sanitary/hygienic
conditions:
￭ Low (juice) viscosity
and average viscosity
fluids (purée).
￭ Products with the
above viscosity that
include small solids in
suspension up to 5 mm.
Xtube® Pharmagrade
Xtube® Pharmagrade is
used to process
products under ultrahygienic and sterilie
conditions:
￭ Low (WFI) viscosity
and average viscosity
fluids (emulsions).
Xtube® Tripletube
Xtube® Tripletube is
used to process
products under sanitary
and non-sanitary
conditions:
￭ High viscosity fluids
(concentrate).
￭ Products with the
above viscosity that
include small solids in
suspension up to 5-10
mm.
Why Corrugated Tubes
Xtube® Corrugated Tubes increase the
turbulence in the flow thus enabling a
more effective mixing and agitation that
generates a higher heat transfer
coefficient than smooth tubes at the
same conditions. Higher U-values
means a smaller heat exchanger.
Furthermore, corrugation carries a "selfcleaning" effect that reduces fouling on
the tube surface. Less fouling means
smaller heat exchanger and longer
production cycles.
Materials of construction
Xtube® Corrugated Tube Heat
Exchangers can be manufactured
out of the following materials:
￭ Austenitic stainless steels like
AISI-304, AISI-316, AISI-316L,
AISI- 316Ti and others.
￭ Superaustenitic stainless steel
(duplex type) like SAF2205,
SAF2507, 254SMO and others.
￭ Titanium.
