The FLYWHEEL advantages
Dynamic energy storage technology with even
more technical advantages:
• outstanding reliability,
• reduced maintenance,
• simplified maintenance,
• long service life (> 20 years),
• max. power in min. volume,
• less floor space < 0.58 m2,
• high efficiency 99.4 %,
• may be used when battery use is impossible
because of critical operating conditions (i.e.
high ambient temperatures).
• self-diagnostics,
• rapid recharging (normally 12 minutes),
•
•

•
adjustable voltage and current parameters,
silent operation,
simple operation,
cabinet on castors for ease of installation,
no load restrictions on ground,
installation requiring no structural work,
cable access via top and bottom sections,
simplified connections,
units coupled in parallel to increase power
and back-up time,
• front access for maintenance,
• environmentally-friendly.
Power storage
Flywheel from 80 to 900 kVA
• Ideal solution for frequent short outages.
• Uses a very high-speed, rotating flywheel.
• Combined flywheel, shaft and generator.
• The rotating assembly is held up by
magnetic bearing levitation, with no contact
with other parts.
• Less maintenance: the internal system
vacuum eliminates friction.
• The flywheel-driven generator supplies
energy to the UPS during a power failure,
thus providing continuous power to the
load.
• When mains power is restored, the flywheel
takes only 7 minutes (configurable) to return
to full speed.
