Chilled Water System Upgrades

Improving the chilled water system for a biopharma giant.
  • Wall with three existing chiller units and two new chillers, including the variable frequency drives.- Gannett Fleming

    Reprogramming the entire system was required to integrate the new with the old and create a cohesive unit.

  • Two new chillers including the variable frequency drives. - Gannett Fleming

    Two variable frequency drives replace two existing motor starters.

  • Chilled water upgrades led to improved system efficiencies and a two year payback  
  • Assessment of systems brought attention to system-wide upgrade opportunities
  • Eliminated unnecessary costs due to system failure on design days when chillers would drop to 95 degrees prior to implementing upgrades.

As a global biopharma company, Bristol-Myers Squibb (BMS) is at the forefront of developing and delivering innovative medicines to patients with serious diseases. Chilled water systems are essential to many aspects of this process. 

In order to make sure the company is meeting the highest level of industry standards and regulations, BMS hired Gannett Fleming to analyze the chilled water system and make updates at one of its facilities. By utilizing the engineering, procurement, and construction (EPC) delivery method, Gannett Fleming acted as a single point of contact and seamlessly integrated new equipment into the existing system’s operations, all while the facility was still in operation. 

What We Did

Gannett Fleming conducted a top-to-bottom analysis of the existing chilled water system at BMS’s Bloomsbury Laboratory and Manufacturing Facility. The firm prepared a detailed report outlining deficiencies and provided a cost-effective recommendation to optimize the efficiency of the system.

Per the report and recommendations, Gannett Fleming procured and managed all required labor and materials to replace two existing motor starters with new variable frequency drives (VFDs) for two existing chillers, including controls and tie-ins. Although only two were being replaced, reprogramming of the sequence of operations for the entire system was required to integrate the new with the old to create a cohesive unit. The work required coordination and oversight of an engineering team, controls vendors, and the client’s in-house mechanical team. The collaboration resulted in a seamless integration of new equipment into the system’s sequence of operations.

Key Features

  • Furnished and installed two new VFDs, which provide greater control and improved efficiencies for chillers and pumps
  • Overcame complex compatibility challenges interfacing with the existing building controls system
  • With improved chiller functionality and the implementation of a new sequence of operation for the pumps, BMS is projected to see more than $78,000/year in estimated energy savings.
