●Flat plate collector features


①Absorber plate
D.Xia Solar use high selective titanium coating film on absorber. High selective titanium coating film is a special developed TiNxOy film by spurting on the copper ribbon through physical vapor deposition (PVD) technology. Working temperature: -35 ~ 150℃
D.xia Solar develop a patent way to spurt a reflection reducing coating and anti-corrosion ceramic membrane on the compound film, thus even after 25 years , the performance can still be above 95% as the initial time.
The absorb ribbon is welded to the copper pipe by USW (ultrasonic welding) technology to minimum the destroy to the metal when welding.




②Insulation
The absorber plate is encased in 25 mm rigid Polyurethane foam, with an option to additional layer of glass wool, retaining the collector’s heat.
③Solar Glass Glazing
The single-pane 3.2-mm solar glass is patterned to reduce reflection and tempered to maximize strength and durability. The 0.03% low iron oxide content enables a high solar transmittance of 91%.
④Casings
All anodized aluminum extrusion casings are made of solid construction available in a natural or black color.
⑤Tubing Grid
5/8” or 8 mm copper risers brazed to 11/8” or 7/8” copper manifolds with optional flow distribution.
