The

battery-free solution

for your UPS system

How it works

A carbon fiber cylinder linked to a shaft with a motor-generator is fully

magnetically levitated, spinning in a vacuum. In an outage, the motor-

generator uses inertia to create the energy needed by the UPS’s DC bus.

Reliable UPS energy storage

Batteries and reliability

There’s a better way

Bridging the gap

Power quality/reliability systems need

energy storage to ensure protected

loads always get clean power. But any

UPS operator will tell you that batteries

are the weakest link in the chain. They:

● Fail unpredictably

Require precise temperature control

Need reinforced floor space,and lots of it

Endanger personnel with hazmats

●Require frequent and costly maintenance

Need total replacement every 2 - 4 years●

●

The Pentadyne energy storage system

is vastly more reliable and cost efficient

while it eliminates lead-acid battery

hazards, maintenance, environmental

impact and that “cross-your-fingers”

approach to power certainty.

This carbon-fiber-flywheel technology

connects with leading brands of UPS

systems – just like a battery cabinet –

but without the dangers, repetitive

costs and poor reliability issues.

Flywheels cover the time gap between

an outage and the UPS generator com-

ing online; they also ensure continuous

power during brief utility disturbances.

Utility feed

ATS

Back-up genset

In a power outage, an automatic transfer switch

(ATS) commands the back-up generator to start.

During this time, the UPS ensures continuous power to the

protected load via batteries or a flywheel. These energy

storage devices power the protected loads until the

utility line returns to normal or the back-up genset takes over.

Makes batteries more reliable...

...Or eliminates batteries altogether

The Pentadyne clean energy system can operate in parallel with batteries

as the first line of defense against power quality disturbances.

During a power interruption, the UPS first draws current from the

flywheel; the batteries are isolated. The flywheel delivers continuous

power to ride through brief events (99% of all outages last <10 seconds,

according to EPRI) or until the backup generator is online.

Unless there is a need for energy storage redundancy,most facilities use

flywheels alone to achieve a real-world-proven 10x reliability improve-

ment without all the hazmats,costs,and risks of battery banks.

with UPS systems” – Electric Power Research Institute (EPRI)

Key features and benefits

Real-world-proven: >10x the reliability of lead-acid batteries

Vastly lower lifecycle costs than batteries and other flywheels

An environmentally responsible solution to UPS energy storage

½ the footprint of VRLAs, and ¼ the weight

Runs near silently within a wide temperature range: no HVAC

Less standby draw than batteries; 1/10th that of other flywheels

No special flooring needs, rolls into place and installs in 1-2 hrs.

Footprint comparisonThe floorspace needed byVRLA battery cabinets for a 400-kVA UPS –

including code-mandated access space – is nearly twice that of a similar

capacity pair of flywheels (green). Compared to a one megawatt set of

wet cells,the flywheel footprint is nearly 80% smaller (orange).
