Powerware Flywheel Solutions
Wherever maximum productivity and system availability is critical, the Powerware PF2 battery-free energy flywheel storage system bridges the power gap, acting as a backup power or battery backup source during power quality or utility disturbances and acts as an effective UPS battery enhancement, battery backup system, or UPS battery replacement for traditional systems.
The Powerware PF2, a DC battery-free energy flywheel storage technology, is an integrated motor-generator-flywheel that stores kinetic energy in a constantly spinning, quiet, low friction steel disc. Compared to traditional UPS battery backup systems, the Powerware PF2 dramatically reduces space requirements, temperature restrictions, UPS battery replacement cycles, and maintenance costs while improving UPS system reliability and operational integrity.
