Solar Collector
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 pipes, no glass tubes. So collectors without corrosion and circulation fluid leaking;
Product Introduction:
Flat plate solar collector is a robust, energy-efficient device designed to harness solar radiation and convert it into usable heat. Ideal for hot water systems, space heating, and industrial processes, it combines durability, high thermal efficiency, and low maintenance, making it a top choice for sustainable energy solutions.
The heat is transferred to liquid passing through pipes attached to the absorber plate. Bontel can supply you different kinds of high quality absorber plate with selective film.

Note : ① Rated efficiency: The total irradiance on the daylighting surface of the collector is 1000W/㎡, and the temperature difference between the average temperature of the collector and the ambient air temperature is 50°C. Calculate the efficiency value of the solar collector according to the instantaneous efficiency equation of the collector's daylighting area. ② Rated power: The total irradiance of the collector lighting plane is 1000w/㎡, and the collector power when the temperature difference between the average collector temperature and the ambient air temperature is 50 ° C is equal to the product of the rated efficiency and theday lighting area and 1000W/㎡. | |||
