Project Overview
Eastern State Hospital’s FSU Chiller Replacement project addressed the failure of two of the three chillers serving several wards in Medical Lake, Washington. Columbia Engineering Group provided mechanical and electrical engineering for this emergency project, which focused on restoring cooling capacity while also improving long-term system resilience.
During the project assessment, CEG identified that one of the chillers had failed only halfway through its expected service life. Further evaluation showed that the close proximity of the solid yard walls restricted airflow around the equipment. As a result, the design team performed airflow analysis and modified the enclosure by replacing select wall sections with cyclone fencing to improve ventilation and reduce the risk of premature failure.
Project Challenge
This project involved more than replacing failed equipment. Because the cooling system served active hospital wards, the work required a response that addressed immediate operational needs while also correcting the conditions that contributed to the equipment failure.
At the same time, the project needed to account for continuity of service during the replacement process. To support that goal, CEG coordinated with local vendors to install temporary chillers until the new permanent chillers could be manufactured and delivered to the site.
Engineering Scope of Work
CEG provided coordinated mechanical and electrical engineering for the emergency replacement project, along with design measures intended to improve long-term maintainability and future response readiness.
⚙️ Mechanical
The mechanical scope included replacement of two failed chillers serving several wards. In addition, the design evaluated airflow conditions and addressed restricted ventilation that had contributed to premature failure.
🌬️ Airflow & Site Modification
After performing airflow analysis, the project removed select sections of the solid yard wall and replaced them with cyclone fencing. This improved airflow around the chillers and supported better operating conditions for the new equipment.
⚡ Electrical
The electrical scope supported the chiller replacement and the permanent provisions needed for future temporary cooling connections.
❄️ Temporary Chiller Provisions
In addition to replacing the failed equipment, the design included permanently installed provisions to connect temporary chillers in the event of future failure, giving the facility a more practical path for emergency cooling response.
🤝 Vendor Coordination
CEG worked with local vendors to coordinate the installation of temporary chillers while the new permanent units were being manufactured and delivered to the site.
Project Outcome
The FSU Chiller Replacement project restored critical cooling service to several wards at Eastern State Hospital and addressed the airflow conditions that contributed to premature equipment failure. By combining emergency equipment replacement with targeted enclosure modifications, the project responded to both immediate system needs and longer-term performance concerns.
Just as importantly, CEG incorporated permanent provisions for future temporary chiller connections. That added flexibility helps support a faster emergency response if cooling equipment fails again, which is especially valuable in an active healthcare environment.
What Made This Project Stand Out
The project addressed the failure of two of the three chillers serving several hospital wards, making timely replacement a critical priority.
Rather than replacing equipment alone, the project identified restricted airflow as a contributing factor in premature chiller failure.
Select sections of the solid yard wall were removed and replaced with cyclone fencing after airflow analysis showed the need for better ventilation.
The design included permanently installed provisions for temporary chillers so the facility can respond more effectively to future failures.
