2. Structure & Material
a) Structure: The middle of the machine is the working chamber, the water system located at the bottom of machine, its top is the control cabinet and control panel. Open the door from front direction. The bottom of the chamber with high-quality PU activity wheel that can be fixed, users can move it according to their requirements positioning. -Single cycling system for air flue in the box, there’s one inlet axis weeding machine which improves the flow amount of air, the heating ability and the whole temperature uniformity in the test machine. -Water source and consumption: Tap water or distilled water for 8liters per day. -Heating method is to heat liner water tank with fast heating speed and high temperature uniformity.
b) Material: -Inner box: high grade stainless steel plate -Outer box: stainless steel plate SUS304 or stoving varnish for option.
3. Spray System
- Using the manual control function of the controller, to observe the spray condition in the open
- door state, so as to adjust or replace the nozzle.
- The machine is equipped with a sprinkler, the sprinkler simulates the temperature upheaval and rain erosion during the rain, with a total of several nozzles, sprayed evenly. The spray time is set by the customer.
- Inner water level is with automatic water replenishing.
4. Light source system
Types of light source (simulate the sunlight) Light source: 4 imported UV fluorescent lamps (ATLAS) with rated power of 40W, UVA-340 and UVB-313 light source for users to choose. Like other lamps, the aging of the QUV tube causes the lamp output to drop, and the QUV without the Irradiance meter control system uses the rotational position method to compensate. This system can be used for many application standards, but it has inherent limitations. This method of changing position does not compensate for the effects of different batches of lamps or the surrounding environment.
5. Equipment ambient environment:
- Grounding resistance cable is less than 4Ω;
- Requires users to configure the device at the installation site for the capacity of the air or power switch, and the switch must be independent for the device (plug-socket is not allowed);
- Temperature: 5℃ ~ +30℃
- Humidity: ≤85%
- Pressure: 86kPa ~ 106kPa
- Power supply: AC220 (±10%) V, 50 / 60HZ
- Power: 4.5KW
