The Altek SD-T2L-10 solar system consists of high-quality components. The thermosiphon non-pressurized seasonal water heater is made up of individual vacuum tubes. Solar radiation energy is absorbed by the absorber and converted into heat to warm the water, and thanks to the efficiently selective coating, the performance of the solar collector is enhanced. This system operates with free circulation of the heat transfer fluid. The vacuum tube is structurally composed of two glass bulbs, with the air between them evacuated, which reduces heat loss.
The design and coating of the tank ensure resistance to corrosion and good thermal insulation.
