High transmittance and low emittance flat plate solar collector

Compact pressurized flat plate solar water heater

Working principle:

Flat panel collectors working principle is different from evacuated tubes collector. A glazed flat-plate solar collector consists of a shallow rectangular box with a flat black plate behind a tempered glass cover. The plate is attached to a series of parallel tubes or one serpentine tube through which water or another liquid (such as an antifreeze solution) passes. Sunlight passes through the glazing and strikes the absorber plate, which heats up, changing sunshine into heat energy. The heat is transferred to liquid passing through attached to the absorber plate. Bontel can supply you different kinds of high quality absorber plate with selective film.

Bontel Advantages:
1.The high weather-proof selective absorbing film from full-automatic magnetron sputtering production line developed by Bontel;
2.With Bonding heat transferring technology and laser welding technology;
3.High quality low-iron tempered glass with surface treatment to get high transmittance and low emittance;
4.Circulation fluid in closed copper , no glass tubes. So collectors without corrosion and circulation fluid leaking;
5.The solid built-in absorber plate can absorb all solar radiation improve working efficiency and integrated well with buildings.

Company Information

BTE Solar Co.,Ltd (BTE) is one of the leading manufacturer of solar hot water systems and photovoltaic system in China and around the world. With many years' experiences and Research, BTE team has developed different kinds of solar collectors for different working temperature and circumstance. The solar thermal products including Vacuum tubes, Flat panel collector(High /low temperature), U pipe and Heat pipe collector, Linear concentrating collector, Steam Collector, Solar Water Heater and commercial system. The solar photovoltaic products including solar panels, solar lamps, power generating system and solar pumps. Sentoc automatic production line and strict quality management system can supply you high quality & long working life products.

The board of chairman Mr. Rongtao,Han is one totally technical guy, he has been do the research of solar key technology from year 2000,With his good technical background and ten years research, Sentoc founded in 2009.

Now,BTE and Aoxin Holdings cooperated developed innovative industry integrated model and successfully build Hebei Aochang Industrial Park, Henan Xuchang Industrial Park, Shandong Jining Industrial Park, Total investment more than USD 20,000,000. The Second production base of Sentoc which located in Hebei Aochang Industrial Park has been finished. On the base of professional technology experiences and cooperation with researching institutes and universities, Sentoc has developed high weather-proof selective absorbing film from full-automatic magnetron sputtering production line. Averagely 1.5min/p can delivery your order in short time. The quick measuring instrument from Germany can do function test on production line which ensure each absorber plate meet our high quality requirements.

In 2014, Sentoc successfully developed the new flat panel collector with "Bonding" technology. Its efficiency is 10% higher than normal blue film collector.

In addition, BTE is the core member of Solar Cooling Equipment Joint Research Center and supply heat collecting design for solar cooling system.

Now, Sentoc not only supply energy saving products to global market, we also supply different energy saving solutions to realize your "Micro-Emission" requirements.
