What are the pressure losses of the DualSun SPRING panel?

Pressurised systems

The pressure losses of the DualSun SPRING panels were measured with a heat transfer fluid comprised of 40% propylene glycol and 60% water at 30 ° C.

** Recommended flow rate for thermal discharge

Note

In the case of several field lines (installation on several lines), as the panels are installed in parallel, the value of the pressure drop will be the value of the most unfavorable field.

Even if the pressure drops are greater in landscape mode, this has no effect on the thermal power of the panels. In fact, the only impact of an increase in pressure drops is more work to be done for the circulator.
