DeRUPS™ – Intelligent Control, Secure Power
The System of Choice for Data Centre Operators
Piller’s unique DeRUPS™ system is proving to be the ideal UPS solution for Data Centre Operators needing systems combining small footprint with high reliability, flexibility, ease of maintenance and maximum return on investment.
Unlike conventional DRUPS (Diesel Rotary UPS), DeRUPS™ electrically connects generated power to the UPS rather than mechanically through a clutch. The system provides physical separation of the standby generator from the Piller UNIBLOCK™ UPS modules within an integrated multifunctional system offering great flexibility, improved ease of maintenance and a more sustainable approach to create an impressively low Total Cost of Ownership.
As well as eliminating the need for space-hungry batteries, DeRUPS™ offers a wider range of configuration options including IP-Systems, a complete freedom of engine choice and flexibility to install UPS and generators as and when the need arises. The benefits of this innovation can also be adopted using Piller’s new Critical Power Module, CPM 300.
By avoiding the use of batteries, the system drastically reduces the space required by as much as 80% whilst improving reliability. DeRUPS™ uses POWERBRIDGE™, a flywheel kinetic energy storage system which massively increases power density per unit. Absorbing energy at the same rate as it can dissipate, POWERBRIDGE™ both stabilises and guarantees smooth operation between generator and UPS unit, with no environmental battery disposal issues to manage.
The Topology of DeRUPS™
In its most simple form, a DeRUPS™ solution entails a single diesel generator electrically connected with a Rotary UNIBLOCK™ or CPM where the generator can be connected in the more conventional upstream position, or equally downstream to the UPS to provide additional security for the critical load.
However, with the removal of a mechanical connection between the diesel engine and the Rotary UPS/CPM, flexibility is increased considerably. Ratings of the generators and the UPS no longer need to be matched and individual ratings of units can be matched to optimise requirements in terms of price and performance. Generators can be centralised in a single power farm facility, with UPS modules distributed around a facility in a mixture of MV and LV configurations to suit individual circumstances.
The Benefits of DeRUPS™
Piller’s DeRUPS™ solution delivers an extremely flexible and versatile solution, which offers benefits to organisations at day-1 and during the lifetime of the facility.
Elimination of Batteries Increases Reliability
The replacement of batteries with a flywheel energy store eliminates the major cause of UPS failure, improving reliability and availability. Furthermore, the flywheel provides “guaranteed autonomy” which does not change throughout the 20-year service life of the product.
Reduced Capital & Operational Costs
A DeRUPS™ solution delivers lower day-one capital costs compared to battery-backed static UPS solution when the holistic costs of building the facility are considered.
The adoption of high-efficiency UBT+ technology, combined with the energy management features provided through the DeRUPS™ Controller, ensures optimised efficiency at all levels of load. Combine this with the fact that DeRUPS™ solutions eliminate the requirements for batteries and it can easily be demonstrated that these solutions offer the lowest Total Cost of Ownership.
Space Savings to Enhance Revenue Potential
The adoption of a flywheel-backed solution eliminates batteries which require large dedicated air-conditioned space. Typically, a DeRUPS™ solution can generate a space saving of up to 80%, enabling the revenue generating potential of the business to be maximised.
By way of example, adopting a DeRUPS™ solution in place of a conventional battery-backed static UPS solution for a 2MW facility (N+1 redundancy and 10 minute End of Life battery), could easily result in an additional white space floor area that would deliver over £600,000 per annum in additional revenue to the business.
