DeRUPS configuration – a reliable diesel rotary UPS solution
DeRUPS (Diesel Rotary UPS) is Piller's high-quality uninterruptible power supply system, combining the reliability of a diesel engine with the efficiency of a rotary UPS. The system ensures uninterrupted power supply for critical infrastructure and is ideal for long-term protection against power grid disruptions.


What is the DeRUPS system?
DeRUPS is an integrated solution that combines a diesel generator with a rotary UPS. Unlike traditional battery UPS systems, DeRUPS uses kinetic energy and diesel fuel, providing almost unlimited runtime as long as fuel is available. The system is ideal for data centers, hospitals, and other critical infrastructure.
How does the DeRUPS system work?
DeRUPS operates in three stages: normally powered by the grid, energy is stored kinetically using a rotating array; in the event of a grid failure, kinetic energy ensures a smooth transition; the diesel engine automatically starts and provides power until the grid is restored or fuel is available. The switchover occurs in milliseconds.


Advantages and areas of application of DeRUPS
DeRUPS offers unique advantages: almost unlimited backup time (as long as diesel fuel is available), no batteries required (less maintenance), high efficiency (>97%), compact design. Applicable in data centers, telecommunications, hospitals, industrial enterprises and government institutions.
How to configure the DeRUPS system?
DeRUPS configuration includes several important parameters: power supply (kW/kVA), voltage and frequency, diesel engine type selection, environmental requirements and integration with existing electrical systems. Piller engineers help select the optimal configuration based on the customer's specific needs and load requirements.


Use of DeRUPS systems
DeRUPS systems are successfully used all over the world: data centers (to protect servers and network equipment), hospitals (to power critical medical devices), telecommunications nodes (to protect base stations), industrial plants (to ensure the continuity of production lines). Piller DeRUPS is a reliable partner where power failure is unacceptable.
