About ZELTWANGER
The ZELTWANGER Group, with ZELTWANGER Maschinenbau GmbH as its core enterprise, provides production-ready individual parts, complex prototypes, modules and complete systems for mechanical engineering – from manufacturing through to assembly. In addition to contract manufacturing, the company develops and builds leak testing devices of the ZED series including automation, software, adaptation and service, as well as solutions for leak testing of battery cells, bipolar plates and aluminium heat exchangers. The third business division, Thermal Management, comprises machine technology for heat exchanger production, among other things fin forming machines (corrugated fin rolling) for aluminium fins. For prototypes and small series, leak testing of bipolar plates and battery cells is also offered as a service (Testing-as-a-Service). The group comprises eight companies at six locations and supplies industries such as Battery/E-Mobility, Hydrogen Technology, Biopharma, HVAC&R and Automotive.
