IEM Rotabloc is an energy storage unit that stores electrical energy in a flywheel. Rotabloc consists of a standard synchronous generator and a simple steel flywheel.
The Rotabloc storage unit is very robust. It does not use fragile components such as power electronics, power capacitors or magnetic bearings. Furthermore, it does not rely on batteries for its energy storage.
The IEM Rotabloc UPS system is very efficient and effective. It is an excellent solution for customers that already own diesel generator sets. Rotabloc provides voltage stabilization, power conditioning, and protection against short outages. The existing diesel generator provides the long-term power backup.
Rotabloc is also beneficial for applications that need protection against short interruptions only.
IEM Power Systems produces Rotabloc UPS systems. IEM is a major manufacturer of electrical distribution and power quality equipment. IEM has facilities in the U.S. and Europe and operates worldwide.
