Goldner Completes Cooling Tower Replacement at Centre Square Using Helicopter Lift

Herman Goldner Co., Inc. finished a complete cooling tower replacement in 2018 for Centre Square, the tallest office building in Philadelphia. The building’s 40+ year-old wooden cooling towers were past their useful life and leaking, causing an inability to cool the entire building. The project required the use of a helicopter to lift the new cooling towers to the roof. The replacement tower will lead to a reduction in water and energy usage for the building and its tenants.
