This product is designed for testing electrical products, enclosures, and seals under rainstorm conditions to verify whether the equipment and components can maintain good performance in wet environments. The equipment features a scientific design that realistically simulates rainstorm environments such as dripping, splashing, and spraying water. With an advanced control system and frequency conversion technology, the rainfall volume, rotation angle of the sample turntable, swing angle of the spray oscillating tube, and swing frequency can all be automatically adjusted.

Technical Specifications:
| User Site Requirements | Room size requirement: ≥ 6 × 4 × 3m (L × W × H). Glass room and drainage channel must be prepared by the user in advance.
Room construction: The room can be built as a glass room or solid-wall room. For solid-wall rooms: the interior walls must be tiled, and the ceiling must be waterproof. For glass rooms: the ceiling must be enclosed (with proper support points) and have waterproof and anti-leakage effects. All walls and the ceiling must be waterproof. Drainage channel to be installed by the user. Flooring: The room floor must be covered with high-quality anti-slip tiles, capable of securing fixing bolts, and must be waterproof and anti-leakage. Drainage channel specifications around the room: The drainage channel should be constructed with a depth of 100mm on the right side and 200mm on the left side (drain outlet side) to ensure smooth drainage. The interior of the drainage channel must be tiled, and covered with cement boards or 304 stainless steel cover plates. Utilities: Please reserve power supply inlet and water inlet/outlet connections near the room entrance during renovation. |
