Low energy consumption electronic pump for hot water circulation in all types of domestic heating systems.

Thanks to the advanced technology employed, the permanent magnet synchronous motor, and the frequency converter, the EVOSTA circulators ensures high efficiency in all applications, with significant benefits in terms of energy saving. For this reason, the EVOSTA circulator not only complies with European Directive ErP 2009/125/EC (formerly EuP)(EEI0,23). The circulator has a built-in electronic device that detects the changes demanded by the system, and automatically adapts the circulator performance accordingly, always ensuring optimum efficiency and minimum energy consumption.


The DAB Evosta is a low energy consumption electronic pump, suitable for hot water circulation in all types of domestic heating systems.
