Load demand in your data center changes all the time. But fan speed and airflow from your legacy computer room air conditioning (CRAC) system likely remain constant. What’s more, fan speed is likely set to accommodate peak loads, which rarely exist. As a result, you’re using energy you don’t need and running up costs. Liebert variable speed drive (VSD) upgrade service allows you to match motor speed to changing load demand, reducing energy costs without compromising data center performance.
