What is the maximum operating pressure of the SPRING panels?
Edited
SPRING4
The maximum allowable operating pressure in DualSun SPRING4 panels is 6 bar.
SPRING3
The maximum allowable operating pressure in DualSun SPRING3 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.
