John Day Dam Powerhouse HVAC Upgrade Industry Day

Provide HVAC upgrade services. This project firstly entails complete replacement of the primary and installation of secondary chillers on two chilled water loops that cool the majority of the powerhouse galleries. The scrapping of the old system and the installation of new chiller skid packages (four skids amounting to nearly 600 tons refrigeration), electrical feeds, chilled water pumps, piping, installation and air handler units is scoped, with re-use of certain elements of these systems based on provided designs in combination with replacement. These systems must be tied into a new automated HVAC control system.
