FAIRFIELD MEDICAL CENTER AHU-11 RESTORATION

THE CHALLENGE.

Fairfield Medical Center (FMC) is an active 220-bed acute care hospital serving residents in Southeastern and Central Ohio. Trusting Limbach as their mechanical maintenance partner, FMC came to our team with the need to improve the airflow and humidity control out of their existing air handling unit 11, which serves the cath labs within their hospital. 

THE SOLUTION.

Due to Fairfield Medical Center’s fixed budget and limited downtime availability, a complete air handler replacement was not a feasible option. Utilizing our in-house engineering team, Limbach Collaborative Services came up with an innovative solution that consisted of replacing the existing supply and return fans with two new fan arrays for both the supply and return. Replacing the fans gave FMC 100% redundancy and improved the airflow to the hospital’s cath labs. Another area of concern was the existing chilled water coil. To provide the hospital with better humidity control, our team installed a new, larger chilled water coil that reduced the relative humidity in the discharge air. The addition of the new chilled water coil allowed FMC to continue to meet the air change requirements within the cath labs, including outside air, even when outside air conditions were not optimal.

Within a four-day timeframe, our team was able to install the new fans, coil, and necessary wiring, leaving Fairfield Medical Center with improved airflow and humidity control and no unnecessary system downtime.
