Vacuum pipe solar collector Big-Pipe 30 pipe/ turbo pipe

Solar Keymark certification!
Total solar collector surface: 4.8 m2
Collector useful surface: 3 m2
Collector width: 2395 mm
Connecting pipes: 2x22 mm copper
Space volume: 14 .5 l

Vacuum tube diameter: 58 mm
Vacuum tube length: 1800 mm< br />Vacuum tube wall thickness: 1.6 mm
Absorber coating: SS-AL-Nx/Cu three target selective absorption coating
Vacuum tube wall thickness: 1.6 mm
Stagnation temperature: 250 C
Big-Pipe (Heat-Pipe) head diameter: 24 mm extra thick
Big-Pipe (Heat-Pipe) head length: 70 mm< /p>

Note:
The head of the so-called Big-Pipe insert has a larger heat transfer surface, ( its diameter is 24 mm instead of 14 mm) so the efficiency is better, but it is more expensive. They are the same in value for money.

Operating pressure: 6 bar
Maximum pressure: 10 bar< /p>

Modern, 30-tube Big-Pipe (Heat-Pipe) system vacuum tube solar collector

New technology, increased heat transfer surface.
Approximately recommended for 360-liter containers.
For larger storage, we recommend several pieces or several tubular solar collectors.
Reliability, operational safety and longevity are guaranteed by high-quality, corrosion-resistant materials: among others, borosilicate glasswhich has excellent heat resistance and a high degree of chemical resistance has), copper is aluminum and stainless steel.

The vacuum pipes are connected dry, so there is no direct contact between the heat carrier medium and the glycol-water mixture.
Using it, possible replacement of pipes is possible even with a charged system.

With a universal support frame that can be installed on both flat and pitched roofs.

The product does not include connecting pipes, roof hook and antifreeze. For health reasons, we do not recommend the toxic antifreeze, but the solar antifreeze found in our products.
Usually 10-15 liters of concentrate is sufficient.

The solar collector is delivered disassembled in a cardboard box.
Simple installation and maintenance
