Profectronics builds test benches for development and series production. This page shows classes of units, industries and examples of units from our own models.
A test bench shows what the customer tests. The test specimens are frequently products before their market launch.
Geometry, characteristic values, test specification and measured data are the property of the customer.
For this reason, this page does not show project reports, photos from test fields of customers or series of measurements.
Profectronics does not give customer names on the website.
A unit that Profectronics builds for you also does not appear on this website.
On request, we describe comparable units.
If necessary, a non-disclosure agreement applies.
The figures are visualisations from 3D models of Profectronics. The characteristic values give the design ranges of the class of unit.
Pressure pulse, temperature cycles, burst test and leak test for heat exchangers and refrigerant components. Design to the Pressure Equipment Directive (PED), ATEX and Machinery Regulation (EU) 2023/1230.
The software contains the test sequences and makes the test report automatically.
Performance measurement on condensers, gas coolers, radiators, charge air coolers and oil coolers.
The unit conditions coolant, oil and charge air as the boundary condition for the test specimen.
Special test bench to the customer specification. The vessel moves on rails and you can access it from the 2 sides. For the characteristic values, refer to the table below.
Test station on castors with protective hood and control desk. Version as a test platform for heat sinks.
Thermal resistance Rth for each load point, from the junction to the coolant. Regenerative DC and AC load, pure water circuit with monitored conductivity.
Pressure vessel with heater, vacuum, nitrogen and sampling for tests under pressure and temperature.

The design follows the refrigerant and the requirements at the installation position.
For R744, the PED is part of the design. For R290, a zone concept with ventilation and gas detection and ATEX are part of the design. Characteristic values: Heat pumps and refrigeration.
Assembly, piping, wiring and factory acceptance test in Neuhofen an der Krems. Machining, sheet metal work, pipework and control cabinet construction with permanent partners.
Devices with sheet metal housing before the final assembly.
Mechanics, printed circuit boards and fluid engineering: Engineering design and product development.
The list gives industries instead of single projects.
The sequence does not show scope or share. Not every industry has units of every size.
6 types of units, in the sequence of the task.
| Type of unit | Task and scope |
|---|---|
| Engineering design and product development | Engineering design in SolidWorks, sheet metal design, PCB design and EPLAN, from the concept to the production drawing. |
| Development test benches | Mechanics, fluid engineering and electronics in one unit, from the measurement task to the test sequence. Control through PLC and LabVIEW. |
| End-of-line test benches | Quality test in production with short cycle times, high availability, documentation and traceability. |
| Conditioning units | Water, glycol, oil and fuel, with control of temperature, pressure and flow. Design to CE and ATEX. |
| End-of-line production lines | Feed, test and assembly processes, evaluation and documentation in one line. |
| Laboratory automation | Automated calibration and test lines for the laboratory, integrated into available environments. |
Profectronics makes the engineering design, the electrical design and the test software with the usual tools of the industry.
| Tool | Application |
|---|---|
| SolidWorks | Engineering design of frames, sheet metal parts and assemblies, pipe routing, production drawings and parts lists. |
| LabVIEW | Measurement and test software, test sequences, data acquisition and record. Profectronics uses the same tool chain as the manufacturers of measurement technology for which Profectronics builds. |
| EPLAN | Circuit diagram, terminal diagram and cable diagram, control cabinet layout and the documentation for the CE technical file. |
| PLC and visualisation | Control of the unit, closed-loop control, safety functions and user interface. Profectronics programs all levels itself. |
| PCB design | Adapter boards and interface boards for measurement tasks without a standard solution. |
The brands in this table are the property of their manufacturers.
An enquiry needs only 5 items of data: test specimen, medium, ranges for pressure, flow rate and temperature, installation site and date. A customer specification helps, but it is not a condition. On request, we describe comparable units.
