Automated Shower Guard

An integrated, automated shower guard diverts the water flow before and after each test to keep the operator dry when inserting and removing the specimens.

Easy to Maintain

The 300 evenly distributed nozzles, which produce rain drops for the test, are easy to clean and maintain. The nozzles can be primed, a process of forcing high pressure water through the system to ensure no blockages.

TestWise Touch

Our TestWise software is user friendly, automating the process of testing and alerting the user of when to grade the specimens based on the ISO standard.

Recirculation Unit

Equipped with an innovative ‘Water Recirculation System’, TruRain is the only Bundesmann tester of its kind which reuses water during testing - resulting in significant cost savings and environmental benefits.
