Steca TPS 20

The pump station is the connecting link between the solar collector system and the hot water storage cylinder, 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 ST15/6 ECO solar thermal pump with an installation length of 130 mm. 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 made from durable screw connection brass.

Air separator DN 20

Specially developed for continuous de-gasification of the heat-transfer fluid for solar energy systems.

Optimal installation site: in the supply line of the collector within the solar station.

Separated air builds up in the air separator, and can be released occasionally by hand.

This is particularly advisable when using stainless steel corrugated pipes in order to completely bleed the system.

Flow display DN 20

Flow rate measuring device with functional inspection.

Optimal installation site: in the supply line of the collector within the solar station.
