St. Louis Zoo – Grizzly Ridge

The new state-of-the-art Centene Grizzly Ridge at the St. Louis Zoo features a new HVAC system powered by a 40-ton Trane air-handling unit supplemented by Trane split systems for condensers and coils. The unit also has a new Knight boiler to heat water used to support the bears’ feeding and sleeping areas in colder weather. A brand new plumbing system was installed with a new kitchen, elaborate irrigation system, drains, and water for the exhibits. A major portion of the project involved an elaborate Life Support System (LSS) comprised of two outdoor and one inside pool regulated by layered, three-sand filters, automated chlorine injections, and ozone injection systems.
