Solarstation ST 25/7 PWM with effiency pump - fully compatible with the overall system
Greater efficiency with the ST 25/7 PWM solar station
With the same design as the RS 25/6 and RS 25/7 solar stations, the new ST 25/7 PWM solar station, just like its predecessors, is perfectly compatible with the solar system. What makes it special is its highefficiency pump, which, thanks to the low power consumption and precise power adjustment by means of the Roth BW-HE and BW/H-HE solar regulation units with their continuous speed control, promises to operate your solar system even more efficiently. Roth solar stations are inspected for leaks before they leave the factory. This saves time and money at the point of installation.
The efficiency pump is specially suited for use in solar systems. The flow meter has been developed for heavy-duty use in solar systems and is set at the factory to take water/anti-freeze mixtures of 40 % to 50 %. It also has an extended display range of 4 to 36 l/min. The solar station supports the connection of 18 and 22 mm copper and precision steel pipes.
