Frequently Asked Questions (FAQ Page)
What happens if the temperature of my solar system exceeds 130ºC?
The SMF cup guarantees its resistance up to 130ºC for one hour. If the temperature exceeds this limit or the stagnation period is longer, the membrane could be irreversibly damaged. Therefore, proper system startup is vital, and in case of risk, a safety condenser vessel should be installed.
How do I check the preload of 2.5 bar?
The preload of 2.5 bar It is higher than that of standard heating vessels. Before installation, use a pressure gauge to confirm this pressure. The final pre-charge should be adjusted according to the static height of the installation and the filling pressure of the solar system.
Why the large glasses (220 liters (from now on) do they have brass connections?
Brass offers greater corrosion resistance and is crucial for long-term performance in large installations, where the durability of connections subjected to high temperatures is paramount.
