Project solar heating system is widely used for providing large amount of hot water, both for home use and industrial use. 1. Collector: φ47-1500, φ58-1800, φ70-2000 the new unit triplet gradation membrane collector vacuum tube is efficient in heat absorption and temperature rising. 2. Inner tank material: SUS304-2B imported food-grade stainless steel. 3. Outer covering material: imported high-quality aluminum-zinc coated steel plate and imported fluorine carbon plate. 4. Heat insulating layer: 50-65mm polyurethane integral pressure foaming. 5. Bracket material: high-quality aluminum-zinc coated and plastic-sprayed bracket with all kinds of colours. The design is more reasonable and the color is more beautiful. Project solar heating system can be fixed flatly or slantly. Certificates: CCC, CE, ISO9001:2000, etc.
