Case Study:  Neonatal Intensive Care Unit AHU Replacement



The Neonatal Intensive Care Unit of a local hospital relies on one Air Handling Unit (AHU) for it's environmental comfort control. The unit is over 20 years old and in need of possible replacement. How do you replace this unit without affecting the environment of the NICU?



In a meeting with the Engineering Department, it was determined that the AHU was in need of replacement. A new AHU was purchased and delivered to the hospital for installation. The new AHU needed to be installed in the same footprint as the existing AHU. This meant the system would be down during the demolition of the old unit and the construction and installation of the new unit. This was not an option.

BION built a temporary AHU above the old unit using parts obtained from salvaged units that the owner had stored. Once the temporary AHU was completed, the system was tested and put into service for a short period of time to confirm the NICU environment would be unaffected.



The temporary system was a complete success. Thanks to BION's creative approach to problem resolution, this was a truly transparent upgrade. The NICU department and it's patients did not experience any downtime or comfort control issues during the upgrade process.
