In what circumstances is a Rotary UPS better than a Static battery UPS?
A Traditional static UPS’s are ideal for clean loads like data centres. Although unsuitable with disturbing loads, such as motors and heating.
Rotary UPS’s use flywheel technology, hence no sensitivity to disruptive loads. Production facilities require seamless power, as a slight variation of power costs millions.
Rotary UPS’s are also better suited for environments where it is very expensive to provide an air conditioned space.
Rotary systems run at higher temperatures (up to 40 degrees) without any deterioration, in contrast to static UPS’s ideally kept at 20 degrees.
Finally, it is possible to achieve efficiencies of over 98%, making rotary UPS’s more efficient than online (this doesn’t of course include running in eco mode).
