Technical characteristics

ESPA Silen Plus variable speed pump

ESPA Silen Plus is the swimming pool pump that incorporates the frequency inverter with an important innovation in its operation to adapt the set to the swimming pool application: the variation of speeds in the work cycles.

ESPA evopool Control System detects the position of the selector valve and transmits it to the pump to automatically activate or deactivate the operating cycle according to that position.

Backwash system that, thanks to a specifically developed cycle, manages to increase the efficiency of the process while shortening the cleaning time, drastically reducing the amount of water consumed and achieving an efficient wash.
