01. Capacity: 150 and 200L.
02. Vacuum tube: 2mm.
03. Aluminum alloy thickness: 2.0mm.
04. Copper heat pipes for rapid heat transfer.
05. Reliable and efficient twin-glass solar tubes.
06. Easy plug-in installation and maintenance-free.
07. Corrosion-resistant silver brazed copper header.
08. Powder-coated (black/brown/silver) aluminum casing.
09. Perfect solar collector for domestic solar water heater systems.
10. Stable solar conversion throughout day (tubes passively track sun).
11. Suitable for commercial solar water heating applications.
12. Ideal for mains pressure water up to 8 bar/116psi.
13. Working principle:
a. Operating of AP solar collector very simple;
b. Solar absorption: radiation by tubes and converted into heat;
c. Solar heat transfer: pipes conduct heat from within solar tube up to header pipe;
d. Solar energy storage: water circulated through header via intermittent pump cycling;
e. Each time water circulates through header;
f. Temperature: 5 to 10°C or 9 to 18°F.
