ARUP ALU-ROHR UND PROFIL GMBH

With walls as thin as 0.26 mm, we design radiator tubes with superior strength, performance, and cost-efficiency at a very compact size and drastically reduced weight. All our aluminum radiator tubes are HF-seam welded and made in our state-of-the-art facilities in Montgomery, Alabama, and Dortmund, Germany. Many of our tubes have been used by some of the world’s most respected engine manufacturers, from racing to complex industrial applications. • Profiles from 13 mm to 52 mm in tube height • Multiple-chambered, dimpled, and end-free tube technologies • Metal strip gauges as thin as 0.26 mm • A wide array of aluminum alloys available TUBE TECHNOLOGIES. Dimpled For high-performance radiators and heater cores to increase the turbulence of the fluid and heat transfer by breaking the boundary layers inside the tubes. Multiple-chamber End-free

Available in a variety of sizes for HVAC, industrial, and condenser applications Our aluminum round tubes can be designed for many industrial and commercial uses, but are ideal for heat transfer applications where weight and space are design concerns, including in HVAC units, manifolds, evaporators, and condensers. Other applications include electrical conduits and general tubing for plumbing and construction. • Available in a variety of sizes for HVAC, industrial, and condenser applications • A wide array of aluminum alloys available • High-strength materials available for high-pressure applications • Internally scarfed round tube

We take pride in bringing new technology to the market to better serve our customers. Whether you need a tube that hasn’t been made before or need help working through a challenging design requirement, we’re here to help. Our custom engineering services include a prototype mill and an in-house tool shop to design and produce customized roller sets tailored to the requirements of your special tube profile. Tell us a little bit about your project, and let’s get started.

In applications with corrosive environments or when enhanced heat conductivity is required, our copper-brass round tubes are available in a variety of sizes and gauges, including an inventory of common profiles in long lengths for immediate delivery. Or they can be customized for your application. • A wide array of copper and brass alloys available, from 65/35 to 85/15 • High-strength materials available for high-pressure applications • Internally scarfed round tube • Straight lengths or coil(s)

For heavy-duty engine cooling, we offer copper-brass radiator tubes that can withstand the heat and pressure demanded by the oil and gas, power generation, and industrial markets. We also offer dimpled tube designs for specialized high-performance applications. • Profiles from 9 mm to 22 mm in tube height • Metal strip gauges as thin as 0.127 mm • Available dimpled or smooth, uncoated or coated, with both leaded and lead-free solder • Multiple pre-tooled profiles in long lengths available for short lead times • A wide array of brass alloys available, including the industry standard 85/15, 70/30, 65/35, and cupro-braze, with corrosion-resistant inhibitors

Our charge air cooler tubes help you meet the requirements necessary to comply with today’s evolving emissions regulations. Whether you need a standard or custom profile, our tubes are tailored to provide the performance and durability required by today’s turbocharged engines. • Profiles from 30 mm to 85 mm in tube height • Metal strip gauges as thin as 0.35 mm • A wide array of aluminum alloys for both CAB and vacuum-brazing applications
