The 47/1500 Evacuated Tube Collector is engineered with precision to deliver exceptional performance in converting solar radiation into usable heat. Its core component is a set of borosilicate glass tubes (47mm in diameter, 1500mm in length) that form a vacuum-sealed environment, minimizing heat loss and ensuring optimal thermal efficiency. Each tube is coated with a triple-layer selective absorber coating, achieving an absorption rate exceeding 94%. This design allows the collector to operate efficiently even in low-light conditions, making it ideal for regions with varying weather patterns.
The vacuum-sealed tubes create a near-perfect insulator, reducing heat dissipation by over 90% compared to conventional flat-plate collectors. The selective coating enhances absorption of solar wavelengths, ensuring high energy yields even on cloudy days. For instance, a single φ47×1500 tube generates approximately 0.35 kWh of energy daily, translating to significant savings on water heating costs.
Unlike traditional systems, the 47/1500 Evacuated Tube Collector employs a dry tube design, eliminating water inside the vacuum tubes. This feature prevents freezing in sub-zero temperatures and ensures continuous operation in harsh climates. The borosilicate glass tubes are resistant to hail up to 30mm in diameter and have a lifespan of over 20 years.
The collector’s modular design allows for flexible installation on flat roofs, pitched roofs, or walls, with adjustable brackets to optimize solar exposure. Its U-pipe heat conduction system requires minimal maintenance, as there are no moving parts or water circulation within the tubes. Routine checks involve inspecting the integrity of the vacuum seal and cleaning the tube surfaces.
Constructed with SUS304-2B stainless steel manifolds and high-density polyurethane foam insulation, the collector ensures corrosion resistance and long-term stability. The aluminum frame provides structural strength while maintaining a lightweight profile, simplifying handling during installation.
By harnessing solar energy, this collector reduces reliance on fossil fuels, lowering carbon emissions and operational costs. For example, a 25-tube system can supply hot water for a 4-6 person household, saving up to 70% on annual water heating expenses.
Residential Water Heating: Ideal for homes, providing sustainable hot water for daily use.
Commercial and Institutional Settings: Efficiently powers hot water systems in hotels, schools, hospitals, and resorts.
Industrial Processes: Supports low-temperature heating needs in manufacturing, agriculture, and food processing.
Swimming Pool Heating: Maintains optimal water temperatures year-round without reliance on electric or gas heaters.
Combined Heating Systems: Integrates seamlessly with heat pumps or boilers for hybrid solutions, ensuring consistent energy supply.
Q1: How does the vacuum-sealed design improve efficiency?
The vacuum between the inner and outer glass tubes minimizes convective and conductive heat loss, allowing the collector to retain up to 95% of absorbed solar energy.
Q2: Can the collector operate in snowy or cloudy conditions?
Yes. The selective coating and vacuum insulation enable the collector to absorb diffused sunlight, ensuring reliable performance even in low-light environments.
Q3: What is the lifespan of the tubes?
With proper maintenance, the borosilicate glass tubes and stainless steel components can last 20 years or more.
Q4: Is professional installation required?
While installation is straightforward, professional setup is recommended to ensure optimal positioning and system integration. Most installers offer warranties for labor and parts.
