The Weiss Technik SunEvent Solar Simulation Test Chamber helps you to simulate the solar effects of sunlight, temperature and humidity on the properties and service life of your products. For many products, light resistance tests – also in combination with other environmental factors – are indispensable, as direct exposure to the sun, heat, cold and humidity affect more than just operating and service life: painted surfaces fade and the ageing of materials is also accelerated.
The new refrigerant R449A is used in all SunEvent solar test chambers. The GWP value of just 1397 ensures safe usage even after 2030, and the refrigerant does not have to be replaced. As a result, we are already surpassing the future statutory standards today and therefore future-proofing your tests, making the equipment easier to maintain and more environmentally friendly.
Solar radiation is simulated with the help of an irradiation unit installed on top of the solar simulation chamber. Metal halide lamps are used as light sources, the emitted spectrum based on global radiation according to CIE publication no. 85, table 4. The irradiation intensity is fully adjustable. Radiation passes through pre-aged, heated, double-glazed filter glass integrated into the ceiling of the test space. Lamp housings are equipped with improved heat dissipation and an optimised reflector.
Thanks to the sophisticated construction and high quality workmanship, the test devices have excellent temperature and humidity consistency and in this way, they guarantee correct and reliable results.
Reliable measurements are ensured by:
