15-tube vacuum tube Big-Pipe solar collector solar collector with 15 vacuum tubes solar energy utilization 6-year warranty

Vacuum tube solar collector Big-Pipe 15 tubes

Din Certco certification!
Total collector surface: 2.21 m2
Collector useful surface: 1.5 m2
Solar collector width: 1270 mm
Connecting pipes: 2x22 mm copper
Space: 4.93 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 head diameter: 24 mm normal thickness
Big-Pipe head length: 70 mm

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

Operating pressure: 6 bar

Modern, 15-pipe Big-Pipe system solar collector

New technology, increased heat transfer surface.
Approximately recommended for 180 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 glass(has excellent heat resistance and high chemical resistance), copper and stainless steel.
The vacuum pipes are connected dry, so there is no direct connection between the heat transfer medium and the
glycol-water mixture.
With its application, possible replacement of the pipes is possible even with a charged system.

The product is delivered disassembled in a cardboard box.
Easy installation and maintenance.
