Liebert®Variable Speed Upgrade Kits

Save Money Through Energy Efficient Operation

Save from $1,700 to $5,100/year per unit

Get more efficient operation from your existing Chilled Water CRAC systems and quick payback through lower electricity costs and utility rebates.

The Variable Speed Drive (VSD/VFD) Upgrade is easily installed on your Liebert Deluxe System/3 Chilled Water systems, providing immediate results with lower electrical bills.

Typically, CRAC fans run at a constant speed and deliver a constant volume of air flow. Adding a Variable Speed Drive to the fan motor allows fan speed and power draw to be reduced as load decreases. A 20 percent reduction in fan speed provides almost 50 percent savings in fan power consumption.
