Centiel has launched its Swiss-designed and manufactured PremiumTower™ S2, its next- generation three-phase UPS solution. Engineered to combine resilience, efficiency, and sustainability, PremiumTower S2 helps organisations protect critical loads while actively reducing their environmental footprint.
With an ultra-efficient architecture that achieves up to 97.1% efficiency in double conversion, PremiumTower S2 reduces energy consumption, lowers heat dissipation, and cuts operating expenses. The system’s design includes no replaceable components for more than 15 years, significantly minimising waste and long-term costs.
PremiumTower S2 features three independent power converters, ensuring power continuity even in the event of component failure. Its market-leading charging capability—up to five times higher than typical standalone UPS systems—eliminates the need for external battery chargers, reducing system complexity and footprint.
Flexibility is at the core of PremiumTower S2. It supports a wide range of battery technologies, including lead-acid, lithium-ion, NiCd, and flywheels, among others. With up to 240 integrated battery blocks (10 to 80 kW) and matching cabinets available for extended runtimes, the system can be tailored to the needs of diverse installations.
Digital intelligence further enhances resilience: smart-predictive fans monitor usage and detect signs of wear, alerting operators precisely when replacement is required—eliminating unnecessary maintenance costs while ensuring ongoing reliability. An intuitive display with its graphical display interface simplifies user interaction, providing immediate visibility into UPS status.
“With PremiumTower S2, we set a new benchmark for sustainable resilience in power protection,” says Gerardo Lecuona, Sales Director, Centiel and continues: “Organisations can rely on robust performance, smarter design, and longer service life while significantly reducing their environmental impact. It’s a solution that reflects our commitment to innovation, efficiency, and a greener future.”
PremiumTower S2 also includes advanced monitoring and communication options, such as SNMP, Modbus, USB, and Bluetooth, ensuring seamless integration into modern infrastructures. Safety is reinforced with built-in backfeed protection and uncompromising reliability through rigorous design standards.
By combining class-leading efficiency, uncompromising resilience, and eco-responsible design, Centiel’s PremiumTower S2 enables businesses to thrive while reducing their ecological footprint.
