The direct-insert type solar collector is a solar thermal device designed for large-scale hot water engineering applications. It heats water directly within the collector and forms a single circulation loop with a large water tank, resulting in high heat exchange efficiency and relatively low investment cost.

Product Features

1. Uses high-efficiency all-glass vacuum solar tubes with uniform coating, strong resistance to thermal shock, and long service life.
2. Inner tank adopts double-sided argon arc butt welding for enhanced durability.
3. End ports feature crimped, weld-free technology with high-temperature sealing to prevent leakage.
4. German fluorine-free polyurethane foam insulation ensures uniform foaming and excellent thermal retention.

Application Scenarios

Widely used in hotels, hostels, schools, hospitals, industrial parks, commercial hot water supply, industrial heating, and district heating systems.

UHS Encapsulation Technology

Solves the industry's leakage challenges. Although butt welding is more complex and argon protection more costly, the result is superior quality. With the combination of double-sided argon arc butt welding and weld-free crimped port technology, the inner tank offers excellent pressure resistance and corrosion resistance, with weld seam lifespan up to 15 years.

Structural Advantages

• 360° Seamless Welding: Double-sided argon arc welding on the tank body provides outstanding pressure tolerance and durability.
• Proprietary Weld-Free Port Sealing: Independently developed crimped sealing technology enhances corrosion resistance and protection.
• High Pressure Resistance: The tank withstands 1.0 MPa test pressure—16 times the national standard operating pressure.
