Liebert FS Flywheel Solution

Liebert FS Flywheel Solution

Reliable Ride-Through Energy Storage for use with, or in place of, UPS Battery Systems

The Liebert FS is designed to provide ride-through power and voltage stabilization during power disturbances when used in conjunction with an uninterruptible power supply (UPS) system.

The advanced flywheel technology used in the Liebert FS provides 120 kW of instant ride-through power and voltage stabilization for 20 seconds or more more than enough for the vast majority of electrical disturbances.

The Liebert FS flywheel power system also offers many advantages over other flywheel-based equipment. Its compact size and lighter weight than competitive units allows easy and modular Installation. This is because of our use of a high-speed, lower weight flywheel compared to the heavy, low-speed type used by the competition. It features extremely low audible noise and requires no bearing or vacuum pump maintenance the vacuum pump is integrated into the flywheel design.

The Liebert FS footprint and weight is small for such a powerful system. The 120 kW system is 71 inches (1.8 m) tall and can fit in as little as 5.7 sq. ft (0.53 m2). It will fit through standard doors and can be moved using a forklift or even rolled into place. The Liebert FS, weighing 1300 pounds (590 kg), is simple to install and provides great installation flexibility. Just roll the unit into position and bolt it down.

The Liebert FS flywheel is a reliable, compact, and cost efficient ride-through power solution. Add to that its virtually maintenance-free operation, ease of installation and operation, lower lifecycle cost and environmental friendliness and you will see why this is the new energy storage alternative that really makes sense.

Key Benefits:
  • Provides ride-through power without the need for batteries.
  • Batteries never need to be replaced.
  • Reduced need for IT equipment air conditioning.
  • Magnetic bearing system eliminates mechanical bearing maintenance.
