Blue Flat Plate Solar Collector
Millionsun specializes in OEM and ODM manufacturing of blue flat plate solar collectors for distributors, solar water heating brands, EPC contractors, and installation companies worldwide.
Key Features & Performance
Blue Titanium Selective Coating
High absorptivity (95%±2%) & low emissivity (5%±2%) for efficient energy capture and low heat loss.
Laser / Back-pack Ultrasonic Welded Absorber
Rearside welding joins absorber sheets and tubes without damaging the coating surface.
3.2 mm Low-Iron Tempered Glass
≥92% light transmittance, impact-resistant and weather-proof.
Full-Copper Flow Channels
Custom dimensions for reliable heat transfer and corrosion resistance.
Aluminium / Copper Absorber Optional
Selective-coated absorbers; ultrasonic or laser welding for superior thermal contact.
6063 Aluminium Alloy Frame
Multiple colour options, anti-corrosion treatment, ideal for building integration.
Glass Wool Insulation
35 kg/m³ density, minimizes heat loss from back and sides.
EPDM / Silicone Sealing
Weather-resistant sealing against moisture and dust ingress.
