Solar Flat Plate


Solar Flat Plate

SDT3.0-L
1.Germany high selective blue coating applied for the absorber;
2.Laser welding between full aluminum absorber and copper tubes ensure good conductivity of heat and
frm structure;
3.Tempered textured glass with high transmittance up to 92%;
4.Super large effective heat absorption area offers higher heating effciency and more energy saving;
5.Mechanical load, freeze resistace, rain penetration, exposure, hail impact, external and internal shock tested etc.
6.25 years life span with max 0.8Mpa pressure.

Working principle:
1.when the temperture of the heat collector reaches the set value,the controller shall start the circulation pump automatically.
2.the circulation pump makes heat-conducting liquid circulate automatically.
3.the heat-conducting liquid transters heat to water by the heat exchanger in the water tank.
4.in case the temperature of the circulation pump does not reach the set value,the circulation pump shall be shut automatically.

Description

SDT3.0-L
The absorber material of SDT3.0-L Series has copper and aluminum with blue selective coating.They are laser welded and have different frame style, dimensions and thickness for option

1. Glazing
Low iron tempered textured glass is used to maximize the solar radiation available and minimize energy emittance. It is extremely strong and hail resistant.
2. Absorber Plate
The FS-FP3.0-D/E/F Series flat plate solar collector are made  by high-efficient blue selective absorber with different dimensions and welding technologies.
Yearly energy yields(Stotten, Germany):
Blue Selective 555 kWh/㎡
3. Risers
Designed for either water or propylene glycol, the 22mm & 25mm diameter headers and 10mm risers conform to international standards.
4. Insulation
Fiber glass is used to insulate the base of the collector to minimize
heat loss. It has 30mm to 50mm thickness for option and has a thermal
conductivity <0.048W/(m.K).
5. Casing
The back plate is constructed with galvanized steel and the frame is extruded with anodized aluminum alloy to provide good corrosion  resistance and light handling capbilities.
