Key Advantages

1. Full Compliance with UL 50E Rain Spray Requirements: the apparatus is designed strictly in accordance with UL 50E specifications, including nozzle spacing, spray angle, hole diameter, and water pressure. The 45° spray angle and standardized flow conditions ensure that enclosure performance is evaluated under realistic rain exposure scenarios, providing reliable compliance data for certification and inspection.

2. Adjustable Spray Height for Flexible Testing: with a spray device height adjustment range of approximately 1000–2000 mm, the system can accommodate enclosures of different sizes and mounting positions. This adjustability makes it suitable for testing everything from small electrical boxes to large distribution cabinets without structural modification.

3. Stable and Accurate Water Control: an electromagnetic flowmeter combined with precise pressure regulation allows accurate control of water flow and pressure. Typical operating water pressure is maintained around 34.5 kPa, ensuring consistent spray intensity and repeatable test results across multiple test cycles.

4. Durable Industrial-Grade Construction: the internal and external structures are made from SUS 304 stainless steel, providing excellent resistance to corrosion, rust, and mechanical wear. The formed aluminum frame ensures structural stability while remaining easy to clean and maintain after repeated water exposure.

5. User-Friendly Operation and Mobility: the apparatus features a simple mechanical adjustment system and does not require complex electrical operation for basic testing. A reinforced base with universal brake casters allows easy movement and secure positioning within laboratories or testing areas.

6. Automatic Water Supply and Purification System: an integrated automatic water supply system with filtration maintains clean, constant-flow water during testing. This reduces nozzle blockage, improves spray uniformity, and minimizes maintenance requirements over long-term use.
