RELIABILITY
A hyperscale hall puts thousands of fans on the critical bus — and with 
conventional ECM walls, the power-quality bill lands at the switchgear. 
Guardian standardizes Infinitum IE5 motors with optional, integral SiC 
Active Front End on every unit: THDi under 1%, 0.98 power factor, and 
ride-through so airflow never dips during a power transfer. Clean power 
isn't an option code. It's how the line is built.
