About this file

Written by GovTribe AI ·

This document is Addendum #2 - Attachment A for RFP 3809 for Variable Frequency Drives (VFDs) over 100HP, issued by Eastern Municipal Water District (EMWD). The addendum provides detailed specifications for VFD equipment at three regional water reclamation facilities: San Jacinto, Moreno Valley, and Temecula Valley. Each facility requires a centrifuge VFD with similar specifications: 150 horsepower, 480 volts, 3-phase, Toshiba brand drives manufactured between 2005 and 2011. The VFDs are used for driving centrifuge bowls, with motor nameplates indicating 125 HP, 142 AMPs, and a service factor of 1.15.

The VFDs are specified as ULH (Ultra Low Harmonics) type, with a minimum current output requirement of 163.3. The equipment details are consistent across all three facilities, including part numbers (VFAS-1-4110KCP-HN or VF AS 1), though serial numbers vary. The document appears to be part of a replacement or upgrade project for existing variable frequency drives at these water reclamation facilities, ensuring continued operational efficiency of critical centrifuge equipment.
