Product Description
Box of 10 ET and 10 HP Packed Together

Evacuated tube
Each evacuated tube consists of two glass tubes made from extremely strong borosilicate glass. The outer tube is transparent and allows sunlight to pass through with minimal reflection. The inner tube is coated with an aluminum nitride (Al-N/Al) coating. This selective surface is excellent at absorbing solar radiation with minimal reflection losses. During the manufacturing process, the air contained in the space between the two layers of glass is pumped out, while the top of the tubes are exposed to high temperatures. This fuses the two tubes together into a single evacuated tube.

ET specs:
Length: 1830mm
Outer Diameter: 58mm
Inner Diameter: 47mm

Heat Pipe
The heat pipe is hollow with the space inside evacuated, much the same as the solar tube. In this case insulation is not the goal, but rather to alter the state of the liquid inside. Inside the heat pipe is a small quantity of purified water and some special additives. At sea level water boils at 100oC (212oF), but if you climb to the top of a mountain the boiling temperature will be less than 100oC (212oF).

This explanation makes heat pipes sound very simple. A hollow copper pipe with a little bit of water inside, and the air sucked out! Correct, but in order to achieve this result more than 20 manufacturing procedures are required and with strict quality control.

HP specs:
Lenght: 1748mm
Wall thickness: 0.7mm

This BOX-ET/HP-10/10 should be ordered with others to install a whole solar collector, and don't sale alone.
