GOC595108 - Consultant - Consulting Services - Replace 2 Packaged AHU’s 2 & 3

Replace 2 Packaged AHU’s 2 and 3 coming to end of their normal life span of 25 years and associated condensing units, CU's 2 & 3. The units are located remotely in the mechanical room on the second floor/upper level of the building and supply air to spaces that require set temperature and humidity for the archives. Conditioned air is delivered to the space 1.08 for AH-2 and spaces 1.31 and 1.37 for AH-3 respectively. SF2 and SF3 provide cooling and humidification for the archival storage rooms. They include all environmental functions—cooling, reheat, dehumidification, humidification, and filtration—and an intelligent control system to make sure every function works with the other. Both AH-2 and AH-3 have an integral micro-processor control system, alarms, infrared humidifier, auto-flush door, fan, motor and isolators. Both systems have electric reheat coil, two step direct expansion cooling coil with hot gas bypass, disconnect switch, compressor sound absorption jacket, and filter bank.
