Company: Air Masters Corp.
Customer: Gateway Arch in St. Louis
Objective: Upgrade the 50-year-old HVAC dual-duct boxes and pneumatic controls inside the Gateway Arch in St. Louis while also keeping the Arch observation deck operational. Air Masters worked closely with National Park Service staff to develop and implement special safety protocol as they worked inside the Arch legs to keep trams operational, workers safe, and visitors comfortable.
Installation: New support steel was installed in St. Louis’ Gateway Arch, followed by new dual-duct variable air volume (VAV) boxes with 12- and 14-inch round duct connections adapted to the original 28- and 30-inch main duct connections. Air Masters also installed Direct Digital Control (DDC) sensors and control wiring for Automatic Controls Equipment Systems (ACES).
Work Completed: The national monument’s 630-foot-tall legs received needed dual-duct boxes and computerized controls to ensure the comfort and safety of tram passengers on their way to the Arch observation deck.
