This item is for one box (10 Tubes) of S-Power Heat Pipe Vacuum Tubes, double coated, 2.0m.

 S-Power Heat Pipe Vacuum Tube Collector Features

The S-Power Heat Pipe Solar Collectors can be used for domestic water heating, space heating, agriculture, process heat, etc. Any application where high temperatures are required

The S-Power heat pipe collector with its integrated stagnation protection will limit the collector temperature to 160°C (320°F)
Dry connection design between the vacuum tube and the header allows each tube to be axial adjusted for peak performance during installation and individually exchanged during operation
One-of-a-kind anti-reflexcoating (nano-coating) applied onto the inner and outer side of the glass tube allows for an extraordinary high light transmission (~97%), a very low light reflection (~3%)
High performance copper absorber (ultrasonically welded), is coated with Titan-Nitrid-Oxide (TINOX), absorbing 96% of the sunlight
The patented and innovative glass-metal connection guarantees the vacuum is always maintained (10 years warranty by the manufacturer)
Made in Germany

 Note - this item does not include the headers or footers

Solar Thermal Performance Comparison:

 Akotec versus Sunrain and most other Solar Thermal Tube Collectors

 You have very likely previously heard the terminology that “not all things are created equal”.

This is especially true when it comes to comparing Solar Thermal Collector Tubes.

A large majority of Solar Collector Tubes are made in China. They may look similar and claim to provide the same results however, under what weather or operating conditions? How fdo they compare with overall performance and longevity? Dollar to Value?

 Below we have provided some data and links to assist you with your analysis.

Place of Manufacture:

Akotec: Germany, Sunrain China

Warranty:

Akotec has a 20 year tube performance warranty, 10 years on the collectors

Sunrain 10 years manufacturer defect

Overheat Protection:

Akotec, has a built-in overheat protection that limits the collector to 100C. This means that if it stagnates for long periods (in the summer, due to power outage or mechanical failure) it won’t damage the system.

Sunrain, nothing

Materials:Akotec is completely made from anodized aluminum where as the Chinese collectors (like Sunrain) are made from powder coated steel which will eventually rust.
