Espa Silen Plus variable speed pump
The Espa Silen Plus pump incorporates the ESPA pool pump with a frequency inverter featuring an important innovation in its operation to adapt the assembly to the pool application: the variation of speeds in the work cycles.
In addition, the Silen Plus pump incorporates a wireless control system, ESPA evopool® control system, to automate the operation of the installation, achieving maximum ease and efficiency of operation.
New tool for calculating energy and water savings with the Silen Plus. The 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.
The result is the most advanced model in the range and the ultimate expression of EVOPOOL® technology with a number of unique advantages:
- ESPA evopool® Control System = automation of the pool filtration system
- ESPA evopool® Filtration Plus = better filtration
- ESPA evopool® Backwash Plus = better backwash
- ESPA evopool® App = Better pump management from a smartphone
- Ultra-quiet operation - 45 dB
- Greater energy savings: electricity (up to 84% savings in electricity) and water (up to 58% water savings).
- Greater economic savings.
- Dry work safety system
- Ease of installation and use
- Model 50/60 H
