Fully integrated collector
hydraulics (fch)
The OWR 12 has fully integrated
1/2’’ collector hydraulics (fch),
with a third connection, includ-
ing sensor wells installed on
both sides. Hydraulic connec-
tion is freely selectable.
Conventional one-side and al-
ternating-side connections
With conventional connection,
the 3rd connection is closed
off with a wind-resistant plastic
cap. Two blind covers close off
the collector array. The connec-
tion can also be realised one-
sided (on the right-hand side or
on the left-hand side).
Tichelmann
With Tichelmann connection,
there is cold flow through the
internal return pipe. The blind
covers are applied to the first
and last collectors as shown.
Corresponding one-sided con-
nection on the right-hand side.
Large-scale systems (Tichelmann)
Large-scale systems, e.g. more
than 6 OWR 20 collectors in a
row, can be connected together
in the centre of the array for
quick, low-loss yields.
II Commissioning
IIb Hydraulic connections
Do not fill the system in direct sunlight.
Danger of steam hammering!
Sensor
Attention!
We recommend connection
according to “A” and “B”.
The sensor is connected to the return side of the collector array.
