ZELTWANGER is a group of eight companies at six locations in Germany, the USA and the Czech Republic. It works in three areas: contract manufacturing, leak testing and thermal management for heat-exchanger production.
ZED-Serie leak testers and test modules (ZEDbase+, ZEDmod, ZEDeco+, ZEDsatellite, ZEDbox, ZEDcore) for leak testing with air. The line also includes the ZEDnet device-management software.
Custom leak-test stations and systems: ZEDstation (semi-automated), ZEDflex (rack-mountable), ZEDsystem (slide table), ZEDcell (automated tracer-gas sniffer testing).
Contract manufacturing of single parts and series by CNC milling on 3-, 4- and 5-axis machining centres, CNC turning of workpieces up to Ø 800 mm and 2,000 mm long, and wire EDM.
Contract assembly of components, subassemblies and complete systems. It includes mechanical, pneumatic and electrical testing.
Automation systems for heat-exchanger production: in-line, one-piece-flow, stand-alone, rotary indexing and robot cells for assembly, handling, marking, dispensing and testing.
Modular end-of-line test systems for heat-exchanger production.
Production system for louver, flat, oil-cooler and turbulator fins from aluminium, stainless steel or copper strip 10–110 mm wide; up to 180 cuts/min single-track.
Calibration under DIN EN ISO/IEC 17025:2018 for the measured quantities pressure and flow, under DAkkS accreditation D-K-21368-01-00.
