About this file
This document is a Request for Information (RFI) related to the replacement of an 80-ton Daikin air-cooled scroll chiller located at Columbus Air Force Base, Mississippi. The key details are:
The government is seeking information on the replacement of the existing chiller, including responsibility for offloading the chiller, electrical specifications, chiller design requirements (entering/leaving water temperatures, GPM, glycol usage), and communication protocol needs (BACnet IP, BACnet MSTP, or LON). The current chiller uses R22 refrigerant and is installed behind the facility in a partially fenced area. The government may be able to provide the specifications for the current chiller. The replacement chiller is to be sole sourced from Daikin and delivered to the base, with the government responsible for installation and startup in accordance with warranty requirements.
