Flat-plate collectors are the most common solar collectors for use in solar water-heating systems in homes and in solar space heating. A flat-plate collector consists basically of an insulated metal box with a glass or plastic cover (the glazing) and a dark-colored absorber plate. Solar radiation is absorbed by the absorber plate and transferred to a fluid that circulates through the collector in tubes. In an air-based collector the circulating fluid is air, whereas in a liquid-based collector it is usually water. Flat-plate collectors heat the circulating fluid to a temperature considerably less than that of the boiling point of water and are best suited to applications where the demand temperature is 30-70°C (86-158°F) and/or for applications that require heat during the winter months. Flat collectors can be mounted in a variety of ways, depending on the type of building, application, and size of collector. Options include mounting on a roof, in the roof itself, or free-standing.

1. Our company located in CHANGZHOU city, JIANGSU province, near to Shanghai port.
2. Our company is founded in 1989, and we have 15,000.00 square meters, so we have great experience in this area, and we have absolute competition for price.
3. We are developing the new product very year, it means that we could meet the new market at the first time.
4. And we know the market very well in the world, because we have exported to Europe, Mid-East, American, and Africa. I could try to introduce the more information in American, because Brazil is large country in American. Now we have market in Mexico,Guatemala, Honduras, Chile, and USA.
5. We have a great working grope for the exporting market, including the market engineer, product engineer, product translator,market manager, and market general manager.
So we hope that we could have chance to know better with each other for the cooperation, and we also trust we could do the best job for this market.
Thank you for reading, and you are welcome to our factory.
Next, please allow us to introduce the split solar water heater for you. Split solar water heater(we usually called SS System), SS is high pressure solar water heater, it could be used in low temperature place, even under the 30 centigrade under zero. Now they are very popular in Germany, UK, Spain, Russia, and USA.
