Product Description

18tubes Stainless Steel Vacuum Tube Solar Collector
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.

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 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

Competitive Advantage:
1. It is the most economical solar collector which is widely used in large-scale hot water heating system, supplying hot water for dormitories, hotels, restaurants, schools, hospitals, factories, swimming pools, and other places requiring large amount hot water application.
2. Special design with all rights reserved by INLIGHT, the arc-angle manifold makes the manifold with much more stress to strike and expansion.
3. INLIGHT glass tube collector can be connected in series-parallel arrays and used in active or passive solar water heating system with stable and reliable performance.
4. INLIGHT glass tube and manifold is anti-freezing device, the collector can be used in extremely cold area with anti-freezing system design and pipeline insulation.
5. High absorption: αs ≥ 90%, low-emissivity: εh ≤ 8%, daily average thermal efficiency ηd ≥ 50%
6. INLIGHT modularized design makes the collector more adaptable to different architecture structure and locations.

Working Principle
Solar vacuum tubes are plug directly inside manifold tank, when cold water in evacuated tubes is heated with solar irradiation, as the specific gravities of hot water and cold water are different, hotter water goes upward to manifold tank and colder water goes downward to glass vacuum tubes. through this continuous circulation, the cold water in manifold tank will be gradually heated, in an active open-loop solar system, the hotter water in manifold will be pumped to hot water storage tank, and the same time circulate colder tank water to manifold collector for solar heating.
