Zero Ground announced recently that Las Vegas, Nev-based Dynamic Commissioning Solutions, Inc. (DCSi) has been added as an Authorized Reseller for the Zero Ground High Frequency Extraction System (HFES). As a professional building commissioning firm, DCSi systematically evaluates building equipment, subsystems, operation and maintenance procedures, and the performance of all building components to ensure that they function efficiently as a system. The Zero Ground HFES solution was engineered for use wherever AC Induction motors are operating in conjunction with Variable Frequency Drive (VFD) applications and for other applications where switching power supplies are used. The design is a completely passive cable assembly system operating on both input and output sides of a VFD. HFES utilizes no filters and requires no maintenance.Learn more from DCSi.
