The Non-Pressure Solar Thermal Collector with 50 Glass Vacuum Tubes is an advanced solar heating solution engineered to deliver reliable hot water for residential, agricultural, and light industrial applications. Operating on an open-loop, gravity-fed principle, this system eliminates the need for complex pressurization mechanisms, reducing installation costs and maintenance efforts. The core component—50 high-performance glass vacuum tubes—employs a double-layered borosilicate glass structure with a vacuum layer to minimize convective heat loss, ensuring exceptional thermal efficiency even in suboptimal weather conditions. Ideal for off-grid setups or regions with intermittent power supply, this collector is compatible with storage tanks ranging from 150 to 300 liters, making it adaptable to diverse user needs. Its modular design allows for partial replacement of components, extending the system’s lifespan and sustainability.
1. Optimized Heat Absorption: Tubes feature a patented three-layer sputtered coating (Al-N/Al) with 95% solar absorption rates and less than 5% emissivity, outperforming standard coatings.
2. Pressure-Free Operation: Designed for open systems, it avoids risks of pipe bursts and eliminates the need for expansion vessels or pressure relief valves.
3. All-Weather Resilience: Vacuum insulation prevents freezing in temperatures down to -25°C and withstands hail impacts up to 25mm in diameter.
4. Eco-Friendly Materials: The stainless steel frame (SS304) and food-grade silicone seals ensure corrosion resistance and safe water contact.
5. Plug-and-Play Installation: Pre-installed mounting brackets and adjustable tilt angles (15°–50°) enable quick rooftop or ground deployment within 4–6 hours.
6. Energy Independence: Reduces reliance on grid electricity or fossil fuels, cutting energy bills by up to 70% annually.
· Single-family homes, villas, and rural cabins requiring decentralized hot water solutions.
· Dairy farms and poultry houses for hygienic animal drinking water heating.
· Small-scale food processing units for pre-washing and sterilization processes.
· Remote schools, clinics, and community centers in developing regions.
· Supplemental heat source for solar-assisted air-conditioning systems.
Q: How does the non-pressure design affect water flow?
A: The thermosiphon principle drives natural circulation—heated water rises to the storage tank while cooler water descends into the tubes, requiring no pumps. Flow rates average 8–12 liters per hour per tube under full sunlight.
Q: Can the system integrate with existing water heaters?
A: Yes, it can preheat water entering conventional electric or gas heaters via a bypass valve, significantly lowering their energy consumption.
Q: What happens during prolonged cloudy periods?
A: The insulated storage tank maintains water temperature for 24–48 hours. A backup heating element (optional) can be added for extended cloud cover.
Q: Are the vacuum tubes fragile during transport?
A: Each tube is individually packaged in EPE foam sleeves, and the entire array is secured with anti-vibration spacers, ensuring 99% arrival integrity.
Q: What certifications does the product hold?
A: Compliant with ISO 9806, Solar Keymark, and CE standards, ensuring global market acceptability.
