UV Aging Test Chamber

Product Overview

The UV Aging Test Chamber (Model: GC-UV-A) is a reliable solution for evaluating material weatherability by accelerating UV-induced aging. It differs from basic aging chambers by integrating advanced temperature control (normal temperature +10~70℃, ±3℃ fluctuation) and high-humidity (≥90% RH) environments, simulating the combined effects of sunlight, moisture, and heat. Key features include a Taiwan Xuan Rong temperature sensor (0.1℃ resolution), non-contact SSR heater control (uniform heating), and a shallow water basin humidification system (anti-dry protection). It complies with Chinese standards (GB/T14552-2008, GB/T16422.3-1997) and international norms (ISO 11507, SAE J2020), making it suitable for both domestic and global markets. Whether for R&D or quality inspection, this chamber delivers accurate, repeatable results to validate material durability.

Core Features

Precise Temperature & Humidity Control: PID self-tuning temperature control ensures stable test conditions; high-humidity environment (≥90% RH) simulates tropical or coastal climates, accelerating moisture-related aging (e.g., mold growth on coatings).

Flexible Operation Modes: Offers both "fixed value mode" (continuous UV testing) and "program mode" (custom radiation/condensation/spray cycles). Touchscreen Chinese menu simplifies parameter input, even for non-technical users.

Low Maintenance Design: Stainless steel armored humidifier (resistant to corrosion) and easily replaceable UV lamps reduce downtime. Circulation fan (Taiwan SUNON) ensures uniform air distribution, preventing local overheating.

Application Scenarios

This chamber is widely used in:

Building & Construction: Testing exterior materials (e.g., vinyl siding, roof shingles) for UV and moisture resistance to avoid warping or discoloration.

Electronics & Electricals: Evaluating outdoor electronic enclosures (e.g., solar panels, street light housings) for protection against UV-induced material degradation.

Textile & Leather: Assessing outdoor textiles (e.g., boat covers, outdoor clothing) and leather goods (e.g., car seats) for fading and tensile strength loss.

Cosmetics & Packaging: Testing UV-protective packaging for cosmetics or pharmaceuticals to prevent product degradation under light exposure.

a) UVA-340: It can emit the wavelength of sunlight from 315nm to 400nm, and its radiation peak is at 340nm. UVA-340 is especially useful for controlled testing of different experiments, best simulating sunlight in the short-wave UV range.

b) UVB-313: The wavelength range is between 280nm and 315nm. UVB-313 tubes cause faster material degradation than UVA-340 lamps, but their shorter wavelength than the solar cutoff can produce impractical results for many materials.

1. UV cycle temperature control:

The components of the UV circulation system include a blower, air heater, air distribution system, black panel temperature sensor.

a) Blower: Installed at the air duct opening of the lower box of the equipment, the blower works continuously during the whole UV cycle.

b) Air heater: installed in the air duct above the blower, used to heat the air blown by the blower when needed.

c) Air distribution system: the air blown by the blower enters the test room through the air duct in the center of the water tray, and then is guided by the air guide to fill the whole test room

2. Condensation system (simulated dew):

The QUV condensing system is essentially where evaporated water vapor is confined within the chamber by the chamber's template. During the condensation cycle, the water is heated by the heating element in the water pan. The water vapor fills the test chamber and reaches equilibrium at 100% humidity. The water vapor continuously condenses on the sample and finally flows back into the water pan.

3. Sprinkler system (simulated rainwater):

The QUV sprinkler system consists of a high-power water pump, 5 nozzles, connecting pipes, control valves and drainage parts. Nozzles are installed between the lamps, and in the spray cycle, water is sprayed onto the sample to create a thermal shock or erosion effect.
