TPS 25
The two-string solar station TPS 25 is a complete
pre-assembled hydraulic unit with integrated Steca 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
prefabrication 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 ST25/6 solar thermal pump
with an installation length of 180 mm. Alternatively, other pump
types with G1½ threaded connectors (e.g. Wilo Star ST25/7)
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.
