To pressurize the circuit, you will also need a compressor and a pressure gauge designed for pressures up to 10 atmospheres.

A simple gas torch is suitable for soldering with soft solder.

Using a pipe cutter, the copper tube is cut into pieces. You will get 2 pieces of Ø22 mm, 1.25 m long, and 10 elements of Ø10 mm, 2 m long.
In thick pipes, make an indentation from the edge of 150 mm japan mobile database make 10 drillings of Ø10 mm every 100 mm.
Thin tubes are inserted into the resulting holes so that they protrude inward by no more than 1–2 mm. Otherwise, excessive hydraulic resistance will appear in the radiator.
Using a gas torch, a heat gun and solder, all parts of the radiator are connected together.
The solar collector circuit operates under pressure, so special attention is paid to the tightness of the connections.

Special fittings can be used to assemble the radiator, but in this case the cost of the solar system will increase significantly. In addition, detachable connections do not guarantee the tightness of the structure under variable thermodynamic loads.

Plugs and threads are soldered in pairs to the 3/4˝ pipes along the radiator diagonals.
After closing the outlet thread with a plug, a fitting is screwed onto the inlet of the assembled manifold and the compressor is connected.
The compressor is connected using a nipple.
