2. Prototype and tests

After concept engineering, we manufacture the required number of prototypes for tests and validation, and install a functional model in the cab or machine. Here, individual components undergo a performance test, and the relevant climatic chamber tests, impact and vibration tests are prepared and conducted. Newly developed products and project-based integration plans can be put to the test in our own climatic chambers (hot and cold tests). In these tests, AC units, complete systems and even vehicles up to the size of a coach can be subjected to tests at ambient temperatures from -40 °C to +55 °C. During this phase, certification for a diverse array of requirements takes place, as do conformity tests and validation.
