Direct Insertion Manifold Solar Collector
· High-efficiency all-glass vacuum tubes with uniform selective coating
· Strong resistance to thermal shock and long service life
· Weld-free end port design ensures leak-proof performance under high temperatures
· CFC-free German-grade polyurethane insulation for uniform and lasting heat retention
The Direct-Insertion Manifold Solar Collector is a robust and cost-effective solar thermal device specifically engineered for industrial and commercial solar heating systems. Featuring a direct single-loop design, it allows water to be heated and circulated directly between the collector and the storage tank—greatly improving heat exchange efficiency and reducing investment costs.
This system is ideal for
· Industrial process heating and domestic hot water
· Commercial building centralized heating
· Agricultural and livestock heating systems
· Swimming pool temperature control
· Solar-powered district heating networks
Core Technology: UHS Sealing System
We apply advanced Ultra-High Sealing (UHS) technology to eliminate common leakage issues in conventional systems. The tank features precision double-sided argon arc welding, combined with weld-free press-fit end caps, providing:
· Seamless 360° internal sealing
· Enhanced resistance to corrosion and pressure
· Weld durability up to 15 years
· Maximum pressure resistance up to 1.0 MPa—16x the national standard
