Product Description
Family Use Solar Water Heater Energy
Products DescriptionThe evacuated tube is the key component to all the thermal heaters and system. It's similar to a conventional Dewar flask and consists of two borosilicate glass tubes, resistant to high chemical and thermal shock. The outer side of the inner tube is coated with a sputtered solar selective surface. This coated inner tube is closed at one end and sealed at the other end to the outer tube. The annular space between the outer tube and inner tube is evacuated to avoid heat loss in conduction and convection. The key element determines function of tube is the technology of the film coating, Gaia Solar tube is the best efficiency tube you can find in China, with the highest absorptance rate of near 97% with common rate of 94% and lowest emission rate near 3% with common rate of 5%.

Advantages
1. Higher efficiency collector, much lower heat loss with vacuum insulation
2. High pressure and super anti-freezing performance in cold weather condition
3. Less heat loss for closed loop circulation
4. No system drainage even though one or several tubes are broken
5. No risk of tube breaking from thermal shock
6. More convenient in system parts carrying and installation

From setup, Gaia Solar engaged in changing steadily deteriorating environment, and invested huge capitals on researching one kind of clean and sustainable energy. With the noble mission, Gaia Solar has become a famous brand in concentrated solar power industry. Gaia researched on solar receiver tube technology more than ten years ago, and as a strategic partner of CASC, Gaia Solar promoted high quality and traceable solar receiver tube RT-4060.
Now, Gaia Solar receiver tubes have exported to more than 60 countries, and got very good business reputations.
Gaia Solar successfully researched out parabolic trough solar collectors PT-5760 and PT-3O, which can be used for solar thermal plant and steam generation. Gaia Solar can provide not only all the facilities to produce high pressure and temperature steam, but also EPC service for the whole solar thermal plant. Now, Gaia Solar has setup its own or cooperated branch company in Spain, Mexico, India, Pakistan, Thailand, Middle-East Asia, East Africa, South Africa and Hong Kong.
