The Hitzinger Rotary Diesel UPS system provides a guaranteed supply of power to protect business continuity against mains failure. The DRUPS (Diesel Rotary UPS System) is the perfect solution for mission critical applications, with the NBDK specifically designed to suit IT grade power requirements. The Rotary Diesel UPS system is made up from four major components, including the Diesel Engine, Electromagnetic Clutch, Hitzinger Alternator and Kinetic Storage module (KIN).

During stand-by operation, the rotary diesel UPS system uses the combination of the Kinetic energy module, alternator and coupling choke to provide a superior source of conditioned power to feed the consumer. In-case of mains failure, the stored energy in the KIN is released as to maintain the speed of the alternator, until the diesel engine can take over (<7seconds) and becomes the driving force of the alternator for prolonged periods of time. These systems provide extremely high availability and reliability in case of mains failure and high efficiency during stand-by operation.

Turn-key, Custom Power Solutions
Hitzinger provides solutions to meet the exact requirements of the project, with multiple design solutions available for internal and external applications. Our team of professional electrical engineers are well versed in up-to-date data enter design and market trends to make sure we deliver energy efficient solutions, providing high resilience in accordance to the Tier classifications (Uptime Institute and TIA942) and low PUE.

Maximum availability and reliability
The reliability of Rotary Diesel UPS systems are measured in MTBF hours. As a comparison, the Hitzinger DRUPS are 4x more reliable (1,000,000hrs) than typical battery backed systems (250,000)

Hitzinger Diagnostic and Monitoring System
Hitzinger offers a complete information software package for monitoring of the system through several means, with remote monitoring modems allowing complete visibility and diagnostic of the system. These solutions allow Hitzinger to minimise down time and guarantee your business continuity.
