Aluminum is the ideal material to produce heat exchangers, radiators, oil-coolers etc. for the automotive industry.

• Light in weight => thin wall
• Brazable
• Clean
• High thermal transfer
• High durability
• Precise dimensions
• Easy to recycle
• Low cost applications.

ARUP supplies a wide variety of customized HF-welded thin-wall round tubes and profiles made from aluminum and aluminum alloys for heat-exchange applications, e.g. for automotive, HVAC or industrial applications.



Flat-Oval Tubes
for radiators and heater components - plain, dimpled or hour-glass (B-Type)

Dimple- or Fish-Bone Tubes for High Performance Radiators and Heater Cores to increase the turbulence of the fluid and therefore the heat transfer by breaking the boundary layers inside the tubes

Hour Glass Tubes for high pressure applications (improved durability tests) and higher performance reached by higher internal Reynolds Number.
Latest development: Plain ends for standard header plates.


• Use one tube in place of two
• Can combine braze and corrosion clad on the I.D.
• Maximize gauge reduction while significantly increasing cycle
durability
• Leak-free welded seam is superior to folded tube leak-path
• May be combined with surface enhancements for the ultimate
in heat transfer and durability performance

Form Free ends: Tubes with dimples, ribs, or the multi-channel hourglass shapes can now also be manufactured with the form eliminated from the tube ends.

• No tube-to-header joint interruption
• Superior leak-free brazing performance
• Uncomplicated engineering design of header and
manufacturing process



Rectangular Tubes for charge-air coolers and special design oil coolers.

New Rectangular Tubes or Box Sections to replace the plastic
tank at conventional radiators. Using aluminum is more cost effective and flexible for different lengths of header tanks.



Round Tubes
for parallel flow condensers, serpentine evaporators as well as for transmission oil coolers.
Oval shapes
are also available upon request.



Our Header Manifolds for PF-Condensers are stamped from a round HF seam-welded tube and delivered to the customer in the required length as a component kit consisting of round tube with endnotch and slots plus endcaps and baffles and including holes for assembling the brackets. Ready for assembly by customer.

Design features
• Seam welded => less leakage
• One piece => no fixing during brazing
• Baffles internally sealed => no external leaking
• Connection holes stamped in required geometry
• Ideal geometry for the insertion of the extrusions
• De-greased and cleaned - ready for your production
• Optimized insertion of the tubes due to formed lead-in radius
along the slots
