Quickly Distinguish the “Twins”—Air-Cooled and Water-Cooled Xenon Lamp Test Chambers Author:LINPIN Update Time:2025-04-14 Source:LINPIN Xenon lamp weathering test chambers are divided into air-cooled and water-cooled types. The main differences between these two types are as follows: Differences in Lamps The air-cooled type uses three imported lamps, each with a power of 2.5 kW. The water-cooled type uses one domestic lamp with a power of 6 kW. Differences in Lamp Placement and Protection Systems In the air-cooled chamber, the three lamps are installed side by side at the top of the chamber and are protected by circulating air. In the water-cooled chamber, the single lamp is installed at the center of the chamber and is protected by circulating water. Differences in Radiation Intensity The radiation intensity of the air-cooled chamber is ≤550 W/m². The radiation intensity of the water-cooled chamber is ≤1200 W/m². Differences in Sample Holder Structures The air-cooled chamber has a tray-style sample holder. The sample tray measures 450 mm × 720 mm and can be manually adjusted in height. The distance between the sample holder and the lamp is 230–280 mm. There are no shape requirements for the tested products as long as they can be placed on the sample tray. The water-cooled chamber has a rotating turntable-style sample holder that can rotate 360°. However, the tested products must be thin and sheet-like. The standard sample size is 75 mm × 150 mm, and the samples are hung on the turntable for testing. The above content summarizes the differences between air-cooled and water-cooled xenon lamp weathering test chambers, and it is hoped that it will be helpful to customers.
