Rain spraying chamber

Spirale vision

This chamber is made of a cabinet that includes 3 dinstinct devices, enabling watertightness tests according to procedures described in standards of the main automobile manufacturers.

The 3 functioning modes are defined according to the wanted sprinkling type :

  • Nozzle mode
  • Ramp mode
  • Half Ring mode

To each mode correspond a type of test and a specific assembly of the samples to test.

The water used for the sprinkling is recycled thanks to a retention tank. Fillings and drainings are automatic.

Each different type of test is entirely piloted by the software Spirale 3 from the command unit with tactile screen.


(according to the functioning mode)

  • Flow rate from 0 to 5 l/min
  • Pressure from 0 to 10 bar
