Built in 1983, One Logan Square is a 32-story office tower in Center City Philadelphia. The building was recently renovated, and the last remaining need was replacement of the original cooling tower. The team decided to replace the three-cell cooling tower to improve efficiency and optimize the building’s systems.

However, the real challenge on this job was the restrictive layout, coupled with the fact that there was no way to get a crane to pull the existing units out and install the new ones. Piece by piece this tower was hauled up to the top of a Philadelphia skyscraper.

Our CTI Certified, counterflow AT 220-918 tower was selected to replace the existing non-certified crossflow units. CTI Certification was the key on this job, since the existing units were underperforming and the owner wanted proven and tested technology that would provide 100% capacity, while fitting the existing space.

Amazing project all around! Kudos to the team that pulled this together!
