Bergen Chiller Plant

This project involved the full replacement of the existing chiller plant at Valley Hospital, addressing aging equipment to improve reliability, energy efficiency, and operational performance. The scope of work focused on the Bergen Building, where the original plant consisted of three 800-ton chillers—one steam absorption unit and two electric centrifugal units. These were replaced with three modern electric centrifugal chillers designed to meet current performance and energy standards. The project also included the installation of new pumps, variable frequency drives (VFDs), and updated controls to optimize system efficiency, provide precise temperature regulation, and enhance overall plant performance. The upgraded chiller plant supports the hospital’s extensive HVAC system, which serves critical clinical, administrative, and support areas throughout the facility. Because the work occurred within an occupied hospital, careful phasing and sequencing were essential. Temporary systems and staged shutdowns were implemented to ensure continuous chilled water supply to the building, maintaining patient comfort and uninterrupted operations throughout construction. Close coordination with hospital operations, engineering staff, and contractors was critical to minimize disruption and maintain safety standards. The completed chiller plant replacement delivers a fully modernized, energy-efficient mechanical system that enhances operational reliability and reduces long-term maintenance requirements. By upgrading this core infrastructure, the project ensures Valley Hospital can continue providing high-quality, comfortable, and safe care for patients and staff.
