Piller was founded in Hamburg 1909 by German engineer Anton Piller.
Built on more than 100 years of German engineering excellence, Piller continues to pioneer the field of uninterruptible power technology, developing industry-leading, state-of-the-art products for a complete range of UPS solutions. Piller occupies a unique position, being the only company to produce a range of rotary UPS and static UPS technologies, encompassing kinetic energy storage systems or batteries, ground power units and 50/60Hz frequency converters.
The Piller company’s superior technology stands behind many of the world’s major financial institutions, data centres, airports, manufacturing and process industries, defence facilities, telecommunications and healthcare providers, ensuring continuity of power supply to mission-critical systems where even the smallest power disruption is unacceptable.

The Rotary UPS is unlike any other UPS. Consisting of a special combination of proprietary motorgenerator and choke, this UPS provides a very simple and highly reliable uninterruptible power solution with exceptionally high efficiencies.

Piller’s rotary Diesel UPS systems of the patented UNIBLOCK type represent the most efficient and reliable power supply combination for critical applications.

The design flexibility of the UBTD+ is unique for a UPS system, it can be used to address low and medium voltage applications, cooling can be by air or chilled water, critical and emergency supplies can be isolated or combined in a single distribution system. Diesel start delay can be varied from seconds to minutes and multiple engine designs can be accommodated.

The UNIBLOCK UBTD+ Diesel Rotary UPS combines all the benefits of a rotary UPS with a Diesel engine in one integrated unit and can work with all brands of Diesel engine used for UPS applications. The UBTD+ is available either with flywheel or battery backed ride-through.

Single machines sized 500 kW up to 2700 kW can be paralleled in standard or IP-Bus configurations for redundancy and added capacity.

UNIBLOCK™ UBTD+ features:

  • Single machines sized 500kW up to 2700kW
  • Paralleling up to 40MW
  • Higher reliability than other technologies
  • Highest partial and full load efficiencies with energy store connected
  • Total design flexibility
  • Medium and low voltage options
  • Battery or kinetic energy store versions
  • Typically 3 times longer bridging time from the POWERBRIDGE™ compared with other rotary UPS
  • Fastest recharge time with POWERBRIDGE™
  • Redundant on-board power supplies
  • Wide leading and lagging load power factor without de-rating
  • Inherent fault clearing ability for downstream short circuits
  • 100% load step capability
  • Virtual unity input power factor 99% input/output harmonic isolation
  • Small footprint and high power density
  • Simple maintenance requirements

Active Power Inc. is an established provider of efficient, reliable and green critical power solutions that ensure business continuity in the event of power disturbances. Our expert system engineers and worldwide service and support teams ensure that enterprises around the globe have the power to perform.

Active Power protects operations in more than 50 countries with premier flywheel-based UPS systems and turnkey power solutions. Our systems are built with pride in Austin, Texas, USA at a state-of-the-art, ISO 9001:2015 registered manufacturing center.

Active Power’s solutions feature flywheels as their central technology, using kinetic energy – energy stored as motion – instead of traditional electrochemical batteries. At the core of Active Power’s ability to solve customer problems is out flywheel energy storage technology.

The concept behind flywheels is quite simple: Objects in motion continue in motion unless acted upon by an outside force. Flywheels have been used for more than 5,000 years in textile spindles and potters’ wheels and were adapted to machine use during the Industrial Revolution.
