Silen Plus is the first product that ESPA launched with the evopool technology. The main characteristic of this product range is its significant savings in water and energy.
 

This pump incorporates a frequency driver that adapts its speed to the installation where it is working, in order to save as many energy and water as possible during the backwash that consumes the most. 

It also comes with the evopool Control System that automates and simplifies de use of the filtration equipment of the swimming pool.

The pump can be manipulated with multiport valve or using the smartphone with the app of the same name. Silen Plus also has an internal clock that operates as a start and stop timer, making external programming unnecessary.

In order to explain clearly all its operating control ESPA broadcasts a series of videos on its YouTube channel in English, Spanish and soon in French.

The latest development of the Silen Plus is the Filterwatch Plus, a system that controls the dirtiness of the filter and recommends a cleaning cycle when this one is saturated (Backwash Plus).

At the same time, the function modifies the pump parameters to maintain a constant filtration speed.
