Product Description

Type 1 (Glass-Glass) tubes consists of two glass tubes which are fused together at one end.The inner tube is coated with a selective surface that absorbs solar energy well but inhibits radiative heat loss.The air is withdrawn ("evacuated") from the space between the two glass tubes to form a vacuum, which eliminates conductive and convective heat loss.These tubes perform very well in overcast conditions as well as low temperatures.Because the tube is 100% glass, the problem with loss of vacuum due toa broken seal is greatly minimized.Glass-glass solar tubes may be used in a number of different ways, including direct flow or heat pipe configuration.Imposol uses a high efficiency heat pipe and heat transfer fin design to conduct the heat from within the evacuated tube up to the header.
