Pressure Drop Per Collector:

The measurement of the pressure drop △p was carried out with water as fluid up to a flow rate of 398 kg/h. The inlet temperature of the water was 20℃. The reason for the high number of measurement points at a low flow rate is given by EN 12975-2:2006. Five measurements of different flow rates in the range of 18 kg/h m2 to 108 kg/h m2 are necessary. The measurements were performed up to a much higher value to increase the accuracy of the parameters. Also, these flow rates are closer to flow rates occuring in collector fields.

The Pressure drop in Mbar can be described by the following funcion of the mass flow X in Kg/H

△p=0.0251825*x+0.000440452*x²

When you connect many collectors together, please consider the pressure drop based on this graph and equation in order to size the pump correctly.

Operating Pressure

Maximum operating pressure is 10 Bar. Operating pressure is 6 Bar.
