RALC Italia to unveil HVAC machinery at Chillventa

RALC Italia will present new heat exchanger and tube-processing systems at Chillventa in Nuremberg from Oct. 13-15, 2026. The lineup includes a patented CNC Wall-ring Machine, a 5-axis machining center with new on-machine programming, and the R135 end-forming machine for tubes up to 135 mm.

Why it matters: - RALC Italia is targeting HVAC manufacturers that want more automation without added programming complexity. - The company is positioning its machines around faster setup, greater flexibility, and simplified operation on the shop floor. - Chillventa is one of the sector’s biggest stages, so the show gives RALC Italia a direct audience of refrigeration, AC and HVAC buyers.

What happened: - RALC Italia will showcase its latest solutions at Chillventa from Oct. 13-15, 2026, at NürnbergMesse in Nuremberg, Germany. - The company will present equipment for heat exchanger production and tube processing. - RALC Italia was founded in 1990 and designs automatic machinery and custom systems for tubes, profiles and sheet metal. - RALC technologies have been exported to 56 countries.

The details: - The featured machine is RALC Italia’s patented CNC Wall-ring Machine. - The Wall-ring Machine forms fan collar nozzles directly on the heat exchanger casing through a progressive cold-forming process using three rollers. - The machine can form multiple fan collars with different custom geometries on the same sheet metal casing. - The process works across aluminum, steel and stainless steel. - The system is designed to support thermal efficiency and acoustic performance through optimized geometries. - For flanged collars, automatic or robotic punching units can be integrated into the cycle. - RALC Italia will also show a 5-axis machining center for manifold tubes. - The machining center combines drilling, milling, flow drilling and tapping in a single automatic cycle. - RALC Italia says it developed a new on-machine programming interface to reduce the complexity of 5-axis programming. - The interface lets operators create and set up new parts without CAD/CAM expertise. - The software can import STEP and DWG files directly and convert them into ISO machine code. - RALC Italia will also present the new RALC R135. - The R135 is engineered for end-forming and closing tubes up to 135 mm in diameter. - The machine supports standard end-closing operations, including flat end closures using specialized tooling. - The R135 can also execute additional end geometries using dedicated tooling and custom operational cycles.

Between the lines: - RALC Italia is leaning into a broader industry shift: advanced machinery that is easier for operators to deploy without specialized software staff. - The company is framing simplicity as a competitive feature, not just a convenience. - Andrea Lazzarini, CEO of RALC Italia, said automation, flexibility and performance remain vital, but making sophisticated technology easy to program and operate is equally important. - The message suggests RALC Italia wants to be seen as a technology partner, not just a machine supplier.

What's next: - RALC Italia will meet visitors and technical teams at its Chillventa stand during the Oct. 13-15 show. - The company is using the event to push adoption of its newest systems among HVAC manufacturers that need short-run flexibility and faster changeovers. - More information is available on RALC Italia’s website.

The bottom line: - RALC Italia is using Chillventa to show that HVAC production equipment can be both advanced and simple to run.
