Glass Tube Solar Collector
1. OEM availlable
2. Economical and efficient collector
3. For large quantity solar heating system

Features description:
The glass tube solar collector (nonpressurized) consists of glass vacuum tube, nonpressurized manifold and supporting bracket, working principle is thermosyphon the same as integrated non-pressurized system, water is heated directly in glass tubes, taking advantage of the natural circulation due to smaller density in hot water than cold water. Series or/and parallel arrays of solar collector is usually adopted for large-scale hot water heating project.

Key Specification:
1. Inner of manifold: SUS-304-2B stainless steel
2. Outer of manifold: Galvanized steel/ color steel
3. Bracket: Galvanized steel with electrostatic plastic coating;
4. Vacuum tube: High boron silicon glass with aluminum bloomed
5. Insulation layer: Polyurethane;
6. Package: Cartons with foam;
7. Angle: We will adjust it according to different countries' latitude.

1. Especially designed for large-scale hot water heating system, supplying hot water for dormitories, hotels, restaurants, schools, hospitals, factories, swimming pools, and some other sites requiring hot water use or house heating.
2. All-glass vacuum tube, most economical and good performance at the same time
3. Processed color steel shell and galvanized angle steel bracket make it a long lifespan as vacuum tubes
4. Easy installation and connection and little maintenance needed

Warranty: 3 years international responsibility for integrated collector exchange and 15 years for glass vacuum tube compensation due to original quality problems
