                         Our solution incorporated precision air handling units with proportional-integral-derivative (PID) control algorithms and rapid response cooling coils to maintain stability during equipment heat load fluctuations.

                         The facility was built inside an existing two story shell building. All our mechanical systems had to be supported independently from the original building structure. Our design included custom pipe racks that were prefabricated off site and shipped in sections to the facility. Coordinated shipping splits for custom air handling units to fit down narrow service corridors. The AHU installation was closely coordinate with the prefabricated pipe rack installation. All utilities were installed successfully and without issue.
