15-tube non-pressure-resistant vacuum tube solar collector 6-year warranty! flow-through collector 15 vacuum tubes Very good price-value ratio

Non-pressure vacuum tube collector

The circulation of water inside the solar collector works on the thermosiphonous/gravity principle. The warm water automatically flows upwards, while the cold water flows downwards, so the natural circulation in the system can start. 

Solar collector structure:

Solar collector section:

Total solar collector surface: 2.36 m²
Solar collector useful surface: 2.03 m²
Connecting pipes: 2x 1" stainless steel (SUS304)
Tube dimensions: ø 58/1800
Vacuum tube wall thickness: 1.6 mm
Number of vacuum tubes: 15
Absorber coating: SS-AL-Nx/Cu three target selective absorption coating
Head unit material inside: SU316 stainless steel
Head unit material thickness: 0.45 mm
Head unit outer coating: PVDF (colored steel plate)
Outer coating thickness of head unit: 0.38 mm
Head unit insulation: polyurethane foam
Head unit insulation density: 40 kg/m³
Head unit insulation thickness: 40 mm
Frame material: galvanized steel
Frame material thickness: 1.5 mm
Frame: 0°-45°
Possible angle of inclination of the collector: 0°-90°
Approximately 135-150 liters for making 60°C hot water suitable daily.

Reliability, operational safety and longevity are guaranteed by high-quality, corrosion-resistant materials: stainless steel and aluminum and, among others, borosilicate glass, which has excellent heat resistance and a high degree of has chemical resistance.

Easy installation and maintenance.

Flow-through 15-pipe collector

Is your garden spoiled by an ugly tank solar collector? Then choose our new technology, with an increased heat transfer surface, which works only with vacuum pipes, without a tank, and is non-pressure-resistant, flowing solar collector. for swimming pool heating, for the supply of summer hot water for hotels and boarding houses.

FEATURES:

1. Non-pressure-resistant, flow-through water heater, large solar collector surface, easy assembly and commissioning

2. Polyurethane insulation, high-pressure foaming process, high thermal conductivity, low heat loss

3. Designed to supply hot water to boarding houses and hotels in the summer (tcannot be used)

4. Perfect for pool heating

5. High efficiency vacuum tube, excellent thermal efficiency, high heat preservation efficiency, does NOT contain copper insert!

It is delivered with a support frame that can be installed on flat and sloping roofs, but the angle of inclination of the solar collector can be adjusted from 0° to 90°.
