What is the maximum operating pressure of the Spring panel?
The maximum allowable operating pressure in DualSun Spring panels is 1.5 bar.
Accelerated aging tests under pressure have been carried out to guarantee their resistance to this pressure over a period of decades. The DualSun Spring panels are all factory tested at 1.5 times this maximum operating pressure, as required by the standards EN 12975 and NF DTU 60.1.
