Function test for electro-hydraulic control units (ehs)
For the automotive industry, ensuring the reliability of electro-hydraulic control units (EHS) is critical. One must perform thorough functional and leak tests to validate the performance of the EHS units and identify any potential issues that may affect system efficiency.

Perform flushing, venting, and temperature control
The JW Froehlich functional test system is specifically designed for electro-hydraulic control units used in automotive transmissions. This two-step process first involves flushing, venting, and controlling the temperature of the hydraulic oil, which is critical for ensuring optimal performance. It then performs a detailed functional check to identify any issues. The double-cycle principle of the test rigs effectively doubles the testing output. JW Froehlich can integrate the client’s preferred test software, or utilize their own proprietary solutions, for seamless integration into your existing systems.
