Model SL-FTRG-58-1.8-XX is one style of heat pipe collectors that have passed Solar Keymark and SRCC. Its manufacturer Sangle put into more than 3 million US dollars in heat pipe collector study, research and test, and finally got Solar Keymark Lecence in 2011-03-21 and SRCC in September 13, 2011. We thank all of you for your support.

Sangle solar collector is a device that absorbs thermal energy from the sun and converts it into usable heat. The heat is normally absorbed by water, or a freeze resistant water mix, which can be used to supplement hot water heating, space heating and even space cooling via use of an absorption chiller or dessicant cooler technology. Special designed for the Heat-pipe solar water heater systems. It's easy to combine with existing water heating systems for family use, commercial, buildings, hotels, hospitals, swimming pools etc. Excellent figure, reliable performance, low maintenance, covenient replacement. One or several glass tubes broken will not fluence system work. Suitalbe to use in all kinds of climates

Technology:
1. The upright tank can make the water temperature to different level. It can hot the top water instantly. The special structure can reduce the cold and hot water to mix together.
2. The tank inside the building, the connection pipe between the tank and water tap is very short, so that hot water can be used instantly and seldom cold water flows out.
3. The tank inside the building, the hot water loses less energy than the normal one.

What we inspection:
1) We will check the inner tank (the content of Ni, the thickness of material, the microelement. )
2) The vacuum tube(knot of glass tube, stone of glass tube, solar selective absorbing coating surface, flash getter, vacuum quality etc)
3) The bracket (thickness of bracket, material purity)
4) The screws (the microelement, thickness of material)
5) The cartons (the strength)
6) The foam (the density)
7) The tank cover (the color)

What we can offer (free):
1) Extra vacuum tubes for afraid of transport breakage.
2) Brochure and CD for installation.
3) 3 years warranty for whole system.

What we can offer (charge):
1) Electric heater
2) Controller
3) Pump
4) Work station(split system)
5) Magnesia rods
6) Three way tubes
7) Valve
8) Flex tube
