Product Name: Solar Vacuum Tube
Specifications:
Vacuum glass tube 47/1800 copper solar energy Dimensions of 1 vacuum glass tube: 180 cm long, 4.7 cm in diameter. -It consists of two glass tubes that are intertwined and vacuumed between them. -The outer tube is resistant to all weather conditions. -The inner tube is made of a transparent and durable, specially compounded glass and coated with a black selective surface. Thanks to this surface, 93% of the sun's rays are absorbed and converted into thermal energy. -Due to vacuum, heat losses through conduction and convection in the tubes are minimal. -Vacuum tube solar energy systems can produce hot water even at -40ºC air temperatures without requiring antifreeze under suitable conditions. -There is no need for an additional power supply for the systems to operate. If any of the glass tubes are damaged due to natural factors, they can be replaced quickly, easily and at very low cost. During the installation, fill the tubes with water and apply soap to the part entering the tank.
Package includes: 24 vacuum glass tubes
