  • UNIBLOCK ROTARY UPS

    The UNIBLOCK range is a key contributor in providing seamless power to your business systems and processes, providing independence from utility power and disturbances on the supply network. UNIBLOCK simply provides confidence in delivering business on schedule day after day, year after year.  Every Piller rotary UPS at heart has the UNIBLOCK rotary machine. The UNIBLOCK is a system with millions of reliable field operation giving high efficiency and performance with minimum components.

    The UNIBLOCK UBTD Diesel Rotary UPS combines all the benefits of a rotary UPS with a Diesel engine in one integrated unit. The system consists of the UNIBLOCK motor-generator connected via a clutch to the Diesel engine, all mounted on a single short base frame. The load is normally fed via an isolating and coupling choke connected to the utility supply. The choke has a second tapped connection to the motor generator. In the event of short interruptions or complete outages, the load is supported initially by a short-term ride through source which can be either a conventional battery system or a Piller Powerbridge (kinetic energy store device). This option is unique to the Piller system. With the load safely supported, the Diesel engine is then given a command to start,and once fully up to speed, it takes over the long term support of the load by engaging the clutch seamlessly.
