The HITZINGER Rotary Diesel UPS Systems can be specifically designed for the application within the chemical industry, by providing uninterruptable power to support a pump system. The Hitzinger DRUPS system will still comprise of the four major components: diesel engine, generator, kinetic energy storage module and coupling choke. The kinetic energy module, generator and coupling choke work together to provide power conditioning and ride through energy for the UPS system, whilst the diesel engine provides the long-term back up for a mains failure. These systems provide extremely high availability and reliability in case of mains failure and high efficiency during stand-by operation.

Technical highlights

  • Hitzinger asynchronous machines with a voltage of up to 11 kV, direct connection to the medium-voltage network
  • Cutting edge engine technology ensures low-polluting emissions of our systems. As an option, our systems can also be designed for optimum fuel economy.
  • Preventive system protection for prolonged service life, system monitoring, coil temperature monitoring, vibration monitoring, ...
  • No downtimes/all but the most essential maintenance is eliminated by automatic lubrication systems, special engine air cleaners and fuel filters that can be switched over during operation.
  • As a general contractor, we are able to realise complete turnkey projects, including aspects such as engineering, execution planning, production with subsequent factory approval, delivery and local installation.
  • Efficiency-optimised version for lowest running costs and lowest total cost of ownership (TCO) with respect to system service life.
  • Redundant start-up. In the worst case scenario where the starter batteries fail or the starter is defective, a back-up solution brings the engine up to speed and the system continues to guarantee an uninterrupted supply to the pump drive.
  • “Black start”: During start-ups or in the absence of a grid voltage, the system can be put into operation by use of batteries or air starters – nothing should prevent the supply of power to your pump drive.
  • EMC-tested, longlife modular controller, 15.4-inch touchpanel with intuitive user menu navigation.
  • Possibility to drive multiple pumps with one unit.
