Our flat plate solar collector is combined with several copper tubes, and there are gaps between each tube. When the sunshine heats the tube, flat collector with its flat surface can absorb the whole sunshine. Therefore, on the same area of the same sunshine conditions, the efficiency of flat collector is 6% higher than the vacuum tube,solar absorption rate up to 95%, and emissivity less than 5%.

With heat-resisting material, our collector can work even in very hot environment, which temperature can be as high as 190°. Besides, our products have got the certificates of the Solar Key-Mark SRCC.
The anti-freezing function of the flat collector is important in cold regions. Normally it has 2 main anti-freezing technologies as follows:
1) Emptying antifreeze technology
It is suitable for the flat plate solar collector system area<100m2. The hot water tank is lower than system pipeline collector when the circulation pump stops working. The water in the collector and pipeline can be automatic to go back to the hot water tank for keeping the collector pipeline empty, so that it can do a help on anti-freezing.
2) Secondary heat transfer system of the anti-freezing liquid Special antifreeze liquid is an anti-freezing heat conduction liquid that combined with the antiseptic and Scale inhibition. It has good performance of heat conduction and can works well under the low temperature of -40°.

Take some large site, hotels and swimming pools and factories for example. When using the solar water heater, normally it needs to combine multi plates together, thus the metal parts to joint different plates together are more stable than the vacuum tube.

Unlike with the vacuum tube, all the tube need to assembled one byone,and it is easy to broken, also some small accessories is easy to lose.

Our flat plate collector is the whole integral part, only to need to use with quick slot to combine together, also it can be installed in flat or slope roof, no limitation of the places.

The absorber plate of the flat collector is consisted of metal materials, also the collector storage tank is connected by metal part. Therefore, it can stand the pressure from the city water supplying and circulation pump. That city water supplying mostly is the centralized water supply system and high pressure, so it is also required that hot water proceed from the collector will be of high pressure. Reducing the pressure difference between water

Flat collector is consist of the frame, back plate, insulation, absorber plate, glass cover and sealing part, and it’s not complex. As for its simple structure, our collector is very easy to process and the mass production of the flat collector can be easily realized. At the same time, it is easy to install and cost-saving.

Different from vacuum tube solar collectors, the flat collector can be installed widely in some places, such as different roofs, balcony also, ;which can be well integrated with architecture. As for its flat structure, the collector can be easily installed, welded and fixed, so it can save time and cost.

All the accessories of collectors are made from high-quality cooper material, having excellent anti-rust, anti-corrosion, and stable performance. So the service life of our flat plate solar collector is quite long, can be more than 25 years.
