To guarantee this electricity supply, Salicru offers a wide range of Uninterruptible Power Supply (UPS) systems capable of providing electricity and preventing power outages. These technological solutions have allowed them to become experts in the water sector and work with the country's leading water utilities, such as Canal Isabel II in Madrid, Aigües de Barcelona, ​​Consorcio Aguas Bilbao-Bizkaia, Aguas de Valencia, Emasesa in Seville, Ens d'Abastament Ter-Llobregat, Aguas de Alicante, and SAIH Norte (Galicia, Asturias, Cantabria, and the Basque Country). This expertise is also reflected internationally, with two notable clients: ONEE in Morocco and Anglian Water Services in the United Kingdom.

The UPS systems supplied to all these companies have enabled efficient power to a wide range of facilities and services at their plants: drinking water treatment plants, desalination plants, pumping stations, reservoirs and wells, intake towers, valves, control centers, flow meter monitoring systems, water quality and salinity level analysis, etc. These features are complemented by other administrative functionalities such as the protection of data centers, computer systems, and billing and customer service processes.

Most of the UPS systems supplied to these companies use online double-conversion technology, currently the most advanced for protecting critical systems, as it provides a perfectly stabilized and filtered sinusoidal power supply. Generally, the most frequently supplied UPS systems belong to the SLC TWIN PRO2, SLC CUBE 3+, and SLC ADAPT series.
