High pressure washdowns Rain Test Chamber EFS-PRO150 to uncover waterproof vulnerabilities


High Pressure Washdowns

Rain Test Chamber EFS-PRO150 to Uncover Waterproof Vulnerabilities


Brief Introduction:

Rain test chamber is an environmental simulation device that replicates real-world rain exposure, road splash, and high-pressure washdowns through programmable water spray systems.


Its primary function is to uncover potential product vulnerabilities—such as seal failure, material degradation, or electrical short circuits—long before the product enters the field.


Technical Specifications:

Internal Dimension2000L
Chamber SizeWidth * Depth * Height 1000×2000× 1000mm
External Dimension

About 4500mmx2800mmx3500mm (Width * Depth * Height)

The actual situation is subject to the final engineering design.

Power SupplyAC380V±5%, 50Hz±1, Three-phase four-wire grounding line (3/N/PE), grounding resistance less than 4Ω
Maximum operating powerAbout 35KW(The final construction design shall prevail)
electric currentAbout 68A (The final construction design shall prevail)
Installation Site

The placement area should have a level floor, good ventilation, and be free of flammable, explosive, or corrosive gases or dust; the site should have no strong vibrations and avoid direct sunlight;

there should be no strong electromagnetic radiation sources nearby;

the floor load-bearing capacity should be no less than 600kg/m²; environmental temperature requirement: 5℃~30℃ for optimal performance;

environmental humidity requirement: ≤85%RH; environmental atmospheric pressure requirement: 86KPa~106KPa;

adequate maintenance space should be left around the equipment.

Compressed airCompressed air supply pressure: 0.6 MPa~0.7 MPa;
The air source quality must at least meet ISO8573.1 Class 2.8.3 standard.
Main Specifications
Wind-driven rain testRoom Temp (RT+10℃) to +55℃
Preheating temperature: ensure the specimen temperature is 10℃ higher than the water temperature

Horizontally adjustable wind speed: 5~18 m/s, allowing raindrops to uniformly hit the test product at an angle of 0~45°.


During rain tests with wind, the position of the rotating table in the test chamber can be adjusted so that the top drip tray is on different vertical axes, enabling raindrops to strike the product at angles of 0~45°.

Effective rainfall area: 800mm * 1600mm
Air vent cross-sectional area: 800mm *1600mm
Rainfall intensity: 100mm~280mm/M2/H, adjustable

Raindrop speed: 9m/s

(By adjusting the height of the top drip tray to allow rainwater to accelerate in free fall, the rain droplet speed of 9 m/s is achieved at the maximum specimen height of 1 m.)

Raindrop diameter: 0.5mm~4.5mm
Rain Test Duration: Continuous rainfall duration ≥4H, adjustable, max 24H
Anti-blocking measures: The rain plate has a needle anti-clogging automatic pressurization and air-blowing function
Others: Fluorescein or similar water-soluble dyes can be added to rainwater.
Strengthening test parametersNozzle pressure: 276kPa~300kPa
Spray surface: For a sample, at least one nozzle should be installed within an area of 0.56 ㎡ receiving the rainfall; there are 5 sprayed surfaces, and the distance between the spray surfaces and the specimen can be adjusted according to the size of the specimen to meet the 48mm requirement. The spray surface near the test chamber door is easy to disassemble and install.
Drip Test ParametersTest time≥40min
Nozzle aperture: 1.0~1.2mm
Spray angle: 60°
Others: Fluorescein or similar water-soluble dyes can be added to rainwater.
Effective rainfall area: 1000mm*1000mm
Rainfall intensity: 100~300L/㎡/h, adjustable
Raindrop diameter: 0.5~4.5mm
Room temperature: (RT+10℃) to +55℃
Preheating temperature: ensure the specimen temperature is 10℃ higher than the water temperature
Drip hole spacing: 25mm * 25mm
Automatic height adjustment: Automatically adjusts the height of the drip tray according to the height of the sample
Raindrop speed: 9m/s, (By adjusting the height of the top drip tray to allow rainwater to accelerate in free fall, the rain droplet speed of 9 m/s is achieved at the maximum specimen height of 1 m.)
Rain Test Duration: 1~9999min, adjustable
The rain tray has a drip hole anti-clogging automatic pressurization and air blowing function
Others: Fluorescein or similar water-soluble dyes can be added to rainwater.
Rotary Test BenchDiameter: Φ800mm rotary table
Material: aluminum alloy plate, set installation screw holes, set anti-slip and anti-tip devices
Turntable speed: 2~7 r/min, speed adjustable
Max load 10 0kg
Top drip trayThe drip tray is driven by a motor, with adjustable height, lifting adjustment range: 0~2500mm
Meet the test requirements stipulated by Procedure I, Procedure II, and Procedure III, and the requirements for the raising and lowering drip pan
Tray area: 1000mm * 1000mm
Nozzle InstallationModular water nozzle, adjustable and removable for replacement
Rainwater treatmentAutomatic waterway recovery, filtration, and recycling
