Large Scale Collector-Flat Plate Solar Collector-Dezhou BTE Solar Co., Ltd

Large Scale Collector

Solar local and district heat can largely contribute to the energy revolution just like solar process heating and solar cooling. In order to meet this demand, we have developed the large surface collector EFPC with its elegant industry design. They are ideal for applications in the medium temperature range, such as solar district heating (SDH) systems, industrial process heat, multi-family residential installations and solar cooling.

BTE BENEFITS:

1.Time Saving: 2 Pole Integrated mounting system for fast and simple installation

2.Investment Saving: Unbeatable value for money thanks to intelligent product design at the highest quality level

3.Assistant Energy Saving: Optimal stagnation and venting behaviour due to meander absorbers designed for large systems

4.Space Saving: Installation sets for a smooth and fast installation; therefore, the installation of 500+ m²/day is possible with a minimal crane

5.After Service Saving: Aluminum frame collector with a high degree of long-term stability satisfies all static requirements
