The CLL Series rain exposure test chambers are systems designed to verify the resistance of components, enclosures and equipment to water ingress and water exposure, through controlled testing dedicated to IP protection verification.
The chambers make it possible to reproduce different rain and water-jet conditions, allowing product sealing performance and behaviour during exposure to be evaluated in a stable and repeatable way.
The CLL Series integrates a fixed and oscillating test arc, a rotating sample platform with adjustable height and speed, and a closed-loop water management circuit. This configuration allows the test to be adapted to DUT dimensions and the required test methodology.
The chambers are intended for qualification, validation and quality-control activities in the automotive, electronics, electrical engineering, lighting, industrial components and other sectors where water protection must be verified.
They are designed to provide:
- controlled DUT exposure to water;
- simulation of different rainfall conditions;
- verification of protection against water ingress;
- adjustable test arc;
- controlled sample movement;
- water flow and pressure control;
- closed-loop water recirculation;
- high accessibility and visibility of the test chamber;
- stable and repeatable test conditions;
- configurations dedicated to different test methodologies.
