Internal tank enameled, external white metal with powder coating, and a universal frame of 2.5 mm, along with a set of pipes and fittings for connection.
Operating Principle of the System
The tank connects to a water supply source, and cold water fills the tank’s space. The solar collector circuit will be filled with a year-round heat transfer fluid, which is included in the basic kit, according to the instructions. Heated by the sun, the heat transfer fluid rises from the collector space to the area around the tank due to natural circulation (thermosiphon principle). The heated fluid gradually transfers its heat to the water in the tank through a common wall.
Tank protection includes 40 mm thick insulation, and hydraulic safety valves are present in both circuits of the system.
System Components
The tank of the Altek LIGERO system is made of high-quality structural steel S235JR, coated with a glass-ceramic finish. The tank has a thickened internal wall (2 mm). The solar collector circuit is designed as a “water jacket” type heat exchanger, through which the year-round heat transfer fluid circulates.
The LIGERO system collectors are perfectly suited for use in thermosiphon systems. The technical specifications are confirmed by the Solar Keymark certificate, and quality and reliability are backed by a 5-year manufacturer’s warranty.
