Testing - Import export

Milling of complex components for automotive and mechanical engineering. Production of prototypes, test parts, small and large series according to data records, drawings, samples or specifications. Machining of cast and forged blanks. Attachment of decorative surfaces.

Based on years of experience in the field of test bench metrology in the automotive industry, EP develops test bench solutions for various applications. We build test benches for testing automotive components such as heat exchangers, intercoolers, filters, valves and others. These are test benches on which e.g. supplier parts for the automotive industry are tested in production. Our specialist knowledge of the industry makes us a strong partner in this area.

We offer you standardised complete systems for the measurement of volume & mass flows. We use measuring elements that have established themselves within previously built customer-specific test benches and convince with high measuring accuracy. We develop and manufacture Venturi tubes and nozzles as individual components or as VMF® complete systems. The VenturiMasterFlow® measuring system, VMF® for short, is used for the precise measurement of air or gas volume and mass flows of 100,000 m³/h. The core of the VMF® system is the FlowProcessor, a PC system with the corresponding data acquisition hardware. Venturi nozzles convince by a low remaining pressure loss and are suitable for flow measurement of gases with high temperatures. The software developed under LabVIEW is operated either via touch screen or with mouse and keyboard.

With the purge air method, heat recovery for balanced air mass flows can be determined for alternating, decentralised ventilation units. The uncertainties of the direct measuring method used so far due to inhomogeneous velocity and temperature profiles at the outlet of the ventilation units are circumvented by the scavenging air method and the measuring accuracy is higher. With the optional humidity conditioning the moisture recovery can also be determined. Further thermal performance indicators are the air volume flow in alternating operation and the balance, which can also be determined with the test bench. The test stand is equipped with an auxiliary fan so that continuously operating ventilation units can also be measured with the direct measuring method.

Apparatus for pressurizing test pieces We offer burst test benches to test load-bearing elements under pressure for their resilience. The components to be tested are put under pressure until they burst. Depending on the requirements (e.g. depending on the medium, pressure range, static or pulsating tests) we build your customized test stand.
