SF serials is Flat panel solar water heater, It include flat panel with pressure or non pressure water tank., Due to. Simply design, economical and practical, small and easy to install.
1. Absorber plate
Absorber plate consists of copper fins ultrasonically welded to copper risers, to provide excellent heat transfer between the fins and the risers, ensuring high efficiency. The absorber core is made of high purity TV1. Also, inexpensive durable aluminum absorber plate is available all allow excellent energy absorption even in cooler climates. 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. The most difficult thing is how to store the solar energy in the TiNxOy film. 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.
2. Insulation
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.
3. Solar 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%.
4. Casings
All anodized aluminum extrusion casings are made of solid construction available in a natural or black color.
5. Tubing Grid
5/8" or 8 mm copper risers brazed to 11/8" or 7/8" copper manifolds with optional flow distribution.
6. Back Plate
The back plate is made of black polypropylene sheet.
7. Aluminum Foil
The aluminum foil acts as a barrier against out-gassing, integrated to the insulation
