TPS 20
The two-string solar station TPS 20 is a complete
pre-assembled hydraulic unit with integrated Pulsar
controller TR 0301. The pump assembly is the connecting
link between the solar collector system and the hot water
storage tank, and includes all fittings and safety devices
for safe and long-lasting operation of a solar thermal
system. Complete pre-fabrication enables quick and easy
installation of all system hydraulics. With the aid of a newly
developed flow rate display, and an inspection glass made
of borosilicate glass, the present flow rate is always
indicated. For increased operational safety of the system,
an optional integrated air scoop can be used as a continuous
air separator in the supply circuit. The standard is a Wilo
Star ST20/6 solar thermal pump with an installation
length of 130 mm.
Alternatively, other pump types with G1 threaded
connectors (e.g. Wilo Star ST20/7) are available at extra
cost. The supply circuit and the circulation pump can be
shut off completely, so that it is not necessary to empty
the entire solar energy system for servicing or pump
replacement. In keeping with our high quality standards,
all fluid-carrying components are brass and completely
screw-fitted.
