NATIONAL GRID

Project Information

Complete upgrade of the mechanical room supporting National Grid’s 50,000 ft2 Main Office Building was completed. 4 air handlers of approximately 30,000 cfm each were replaced, 4 modular chillers were replaced, chilled water and condenser water pumps were replaced and re-piped. A heat exchanger was added to the system to separate the existing geothermal well water from the building’s condenser water to solve the existing issue of broken and blocked condenser water coils. The motor control center was upgraded, and HVAC controls were upgraded from pneumatic to electronic.
