BEIJIN JIUYANG INDUSTRY CO.,LTD, Be founded in 1987.we have 20 years experience in Researching and Producing solar products, especially FLAT PLATE SOLAR COLLECTORS. We have three series products (TXT coating solar collectors, black chrome coating solar collectors, TINOX coating solar collectors.) and difference size flat plate solar collectors(2 square meter,3 square meter.2.97 square meter etc). the flat plate solar collectors be wide used on roof ,wall and balcony.
Our product already received the certification of ISO9001:2000.and obtained the patent techniques of Member-collector(Patent code:ZL20030 0121668.9) we are the member company of China environmental protection institution ,the member company of China Agriculture Energy line institution; the editor company of Beijing Solar Heat System Project Standard.
The advanced produce line, high quality manage and control system will supply high quality goods to you. You are very welcome cooperate with us!
Features:
1. the key part of the collectors is the absorber core that is be produced by high quality all copper. We use the best welding technology ultrasonic welding. There are high quality, less heat losses and more use longevity(up to more 30 years).
2. we use the high quality black chrome coating, absorption is 93%--95%.emissivity is 9%--10%.
3. we will going on the pressure test for 0.9Mpa after finished the core produced.. insure the flat plate solar collectors have stable faction.
4. we use high quality aluminum-alloy frame ,it be produced by special technology, beautiful and long lifetime.
5. we use the high quality tempered glass , the thickness up to 4mm.resist to hailstone and ageing.
6. we use the rock wool as the collectors? back. Heat insulation. We use the polyethylene board and aluminium foil paper as the frame insulation. Good heat preservation efficient and less heat losses.
