DN Solar Energy Co., Ltd.
Brief information
Xiamen DNSolar Co., Ltd. is a professional high-tech enterprise integrating manufacture,
development, research and marketing of flat plate solar collector for thermal water heating
system.
Flat plate solar collector :
1, Black chrome selective coating
Such kind of coating is popular in South Euro, North America and Australia.
Perfectly stocked is a must to black chrome copper fin. In our workshop processing, we move
the plastic film on the black chrome only before glazing. The plastic film is used to protect the
black chrome copper fin.

2, Blue sputtering selective coating
Such kind of coating dominate the German solar market and are popularly used in North
&West Euro .Since it is good performance at emittancne, it get relatively better performance
when applied in cold areas. Perfectly stocked is must to blue copper fin. The plastic film is
used to protect the blue copper fin. Our blue sputtering collectors are popular in Europe,
Australia and North America.
