Description
The Steca TPS 25 two-string solar pump station is a complete pre-assembled hydraulic unit with an integrated Steca TR 0301 controller.
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. In order to further increase the operational safety of the system, an optional integrated deaerator can be used as a continuous air separator in the supply circuit. The standard is a Wilo Star ST25/6 circulation pump with an installation length of 180 mm. Alternatively, other pump types with G 1½ 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.
