  • IPX3 & IPX4 Water Spray Test Chamber


    Chamber material: SUS stainless steel plate

    Stainless steel swing pipe: the radius is R400mm, and 24±1 nozzle is evenly distributed every 50mm on the entire circumference. The pendulum tube drive device uses a motor to adjust the pendulum speed of the pendulum tube. It is realized by mechanical transmission such as motor driven reducer, eccentric wheel mechanism, gear rack and pinion. Adjust the desired angle by means of an eccentric mechanism.

    Stainless steel table: with rotation speed regulation function.

    Tempered glass door: can directly observe the working state of the rain.

    Detachable special nozzle: made of copper, specially processed, the spray direction of each nozzle can be adjusted (within 45 ° range), and finally the adjusted nozzle can be adjusted to a plane, facing the same center point. (This is one of our know-how).

    Stainless steel water supply tank: equipped with water pump, water quality filter, inlet float valve, drain valve.

    Drainage hole: at the bottom of the chamber to be able to discharge quickly, no water accumulation.


    High-precision LCD program controller to complete the time and sequence control of the entire system;

    Imported frequency converter to control the speed effectively ensures that the test runs according to the standard;

IP series



Protected against falling water

Equivalent to 3-5mm rainfall per minute for a duration of 10 minutes. Unit is placed in its normal operating position.


Protected against falling water

when tilted up to 15 degrees - Same as IPX-1 but unit is tested in 4 fixed positions - tilted 15 degrees in each direction from normal operating position.


Protected against spraying water

Water spraying up to 60 degrees from vertical at 10 liters/min at a pressure of 80-100kN/m2 for 5 min.


Protected against splashing water

Same as IPX-3 but water is sprayed at all angles.


Protected against water jets

Water projected at all angles through a 6.3mm nozzle at a flow rate of 12.5 liters/min at a pressure of 30kN/m2 for 3 minutes from a distance of 3 meters.


Protected against heavy seas

Water projected at all angles through a 12.5mm nozzle at a flow rate of 100 liters/min at a pressure of 100kN/m2 for 3 minutes from a distance of 3 meters.


Protected against water immersion

Immersion for 30 minutes at a depth of 1 meter.


Protected against water submersion

The equipment is suitable for continual submersion in water under conditions which are identified by the manufacturer.


Protection against high-pressure water splashes

The water pressure should be 8–10 MPa (80–100 bar) at distance of 0.10–0.15 meters.The water temperature should be 80 °C.
