Home / Test systems
Basic directions of our systems
We build bespoke machines – every system is individually developed, planned, built and implemented according to the test object – from the complete vehicle to the individual component –, place of use and test objective. These five directions show the basic range, but are not a fixed range.


In-line integration
Fully integrated into the continuous production process, conveyor technology included.

Variable system
For development and suppliers: variable intensity, duration and inclination.

Audit system
Targeted long-term spraying for quality audits and sub-units.

Mobile system
Transportable and flexible – used directly at the customer’s site.
Long-term water test
For tests lasting hours rather than minutes, when seals and bonded joints have to hold under continuous load.
Your requirement does not fit any of these directions?
That is exactly why we build bespoke machines: we develop the right solution for your vehicle, component or machine, your cycle time and your place of use – from scratch.
What makes our systems special
As a builder of bespoke machines, we think beyond the test equipment itself – here are a few points we pay particular attention to.
Tailored to your building
We plan every system to suit existing halls, ceiling heights and space conditions – instead of imposing standard dimensions.
Well-engineered technology
Control system, conveyor technology and spraying from our own design engineering and manufacturing, matched to one another.
Filtration & oil separation
Integrated filter and oil separation systems ensure clean, environmentally sound operation.
Software
Rain Test Web: testing goes digital
With Rain Test Web, the entire process from spraying and testing to repair is recorded digitally and integrated into your existing processes and systems.
What the software does
- Control and monitor the system from a tablet or PC
- Register vehicles by barcode and call up the complete test and repair history
- Start a new spraying cycle directly from the application
- Record leak points in the vehicle during testing on a tablet, with a photo
- Pass test and repair data to your ERP system, e.g. SAP
Developed with Basebyte
The web application was created together with Basebyte GmbH: easy to use, even for untrained staff, and modular, so it can grow with your requirements.

Briefly describe your project – the test object (vehicle, component or machine), quantity and place of use are usually enough for an initial assessment.
