Structure and Functions
Ø The exterior chamber is fabricated from high-quality A3 steel plates processed by CNC machinery, with the surface finished in a durable powder coating. The interior chamber is constructed from SUS304 mirror-finished stainless steel panels；
Ø Insulation materials consist of high-density fiberglass and high-pressure polyurethane foam for enhanced thermal isolation；
Ø The temperature and humidity circulation system adopts a specially designed low-noise, long-shaft fan motor paired with a stainless-steel, multi-wing impeller capable of withstanding high and low temperatures, ensuring strong convective vertical diffusion circulation；
Ø A double-layer high-temperature-resistant elastic sealing strip is applied between the chamber door and the chamber body to ensure a tightly sealed test area. The door uses a counter-force-free handle for easier operation, and the chamber is equipped with high-quality lockable PU casters at the base；
Ø The system employs American-imported power supplies and trigger devices. The xenon lamps are also imported from the United States, with a service life of 1800–2000 hours；
Ø Equipped with daylight filters (quartz glass) and window glass filters (tempered glass)；
Ø The chamber includes a water-spray system, and the touchscreen controller allows programming of intermittent spray functions and spray intervals；
Ø Configurable with one or multiple irradiance meters. Available irradiance meter specifications include UV 340 nm, 420 nm, and 300–400 nm；
Ø Equipped with one black panel thermometer and one black standard thermometer, either of which can be selected by the user；
Ø A 7-inch touchscreen is provided for displaying and controlling system parameters；
Ø Electrical components adopt imported brands such as ABB, Omron, and Carlo Gavazzi, or UL-certified components from Noyak, meeting U.S. electrical safety requirements；
Ø Refrigeration components use imported brands including Tecumseh, Castel, Danfoss, and DuPont.
Compliance with Standards
The chamber is designed and manufactured in strict accordance with the following standards:
GB/T 16422.2-99, GB/T 1865-2009, GB/T 9344-98, GB/T 14522-2008, GB/T 2423.24-95, ASTM G155, ISO 105 B02/B04, SAE J2527, SAE J2412, and related specifications.
