SUS304 UV Aging Test Chamber
Large UV Test Chamber UVA Bulbs Accelerated Test Equipment for Solar PV
Sanwood large UV test chamber, also called UV chamber, ultraviolet aging test chamber of photovoltaic module testing adopts fluorescent ultraviolet lamp to simulate the UV spectrum in sunlight, and combines with temperature control and humidity supply devices to simulate the degree of damage caused by environmental climate to materials, such as discoloration, strength and brightness reduction, cracking, pulverization, peeling, oxidation, etc, The equipment has the advantages of solar UV simulation, low maintenance cost and easy to use. The equipment adopts touch screen programmable controller to automatically run the test cycle, with high degree of automation, good light stability and high recurrence rate of test results. It is suitable for aging test of all kinds of products or materials, plastics, rubber, coatings, paints, petrochemical, automobile, electric vehicle, textile and other industries.

Large UV chamber Features:
◆ The main controller of the test chamber is an intelligent digital display controller, which is easy to learn and use with the humanized design.
The shell and inner liner are made of high-quality stainless steel, and the sample holder is made of frame type base frame liner plate and spring.
◆ Digital correction system is adopted for input, with common thermal resistance built in, and the measurement is accurate and stable.
◆ The surface of the sample is transferred to the non irradiation state at night after the specified irradiation time. At this time, the surface of the sample is still exposed to the saturated mixture of indoor hot air and water vapor for heating, while the back of the sample is cooled by the air in the surrounding (condensation) space to form the exposure state of condensation on the test surface.
◆ Original UVA or UVB lamps from America, ensure the comparability of testing results.
Large UV chamber Functions:
◆ Water Spray and Condensation function
1) Water spray The large UV chamber SM-UV2000 spray system designed with 16 nozzles. Spray system can run a few minutes and then shut down. This transitory water spray can cool the samples quickly, creating heat shock conditions.
2) Condensation In many outdoor environments, materials are placed in wet condition for over 12 hours each day. Studies have shown that the main factor of this wet condition outdoor is caused by dew, not rain. Sanwood large UV chamber SM-UV2000 simulates the outdoor moisture erosion through the unique condensation capabilities. In the condensation cycle during the test, water on the bottom of the chamber is heated to obtain superheated steam filling the test chamber.
Hot steam makes the chamber maintain 100% relative humidity, and maintain a relatively high temperature. Sample was fixed on the wall of test chamber. Thus the sample surface is exposed to the ambient air of test chamber. The other side of the sample is exposed to the natural environment which has a cooling effect, bringing internal and external surfaces of the sample with temperature difference, and the temperature difference leads to the test surfaces always have drips caused by condensation process.
◆ Ultraviolet simulate
The large UV chamber SM-UV2000 equip with 16 pieces UVA or UVB lamps, which can simulates the sunlight covering the spectrum. UV lamps origin from Q-labs.
◆ Temperature and humidity environment in the working room.
Control the temperature automatically with high precision Pt 100 temperature sensor of black board.
In each cycle, the temperature can be controlled at a set value. At the same time, the black panel thermometer can monitor the temperature. Temperature increase can accelerate the aging process, and the temperature control for reproducibility of the test is also very important.
BST (Black panel thermometer)consists of a PT100 sensor and a metal panel painted by black coating, and be exposed to the same condition as test panels. It’s used to monitor exposuring test panels surface temperature during test. BST can be set any value according to different requirements and also be controlled automatically during the whole test. It also can be calibrated periodically.
