Enhanced Operational Efficiencies

Piller’s UPS offering is truly best in class with a number of UBT+/UBTD+
rotary as well as AP Premium static UPS products being eligible under
the UK Governments Enhanced Capital Allowance (ECA) Scheme, which
rewards the adoption of high-efficiency technology through accelerated
capital allowances. In addition, Piller’s in-built Power Economy
Management feature ensures low operational losses where load levels
are cyclical or difficult to predict.

Rotary Product Offerings

Piller’s rotary UPS solutions are built around the renowned UNIBLOCK™
system delivering outputs from 150 kVA to 50 MVA in both independent
and diesel-based configurations with a range of energy storage options.
The latest evolution, the UNIBLOCK™ UBT+ offers over 97% efficiency,
the highest levels of reliability and versatility making it ideal for new and
existing installations utilising RUPS, DRUPS and DeRUPS™ topologies.

Piller also offers the POWERBRIDGE™ kinetic energy storage system, a
vertically-mounted flywheel which is electrically connected to the
