This opportunity appears to have a confirmed incumbent and/or closely related prior contract based on prior awards for Multistack chiller parts. A prior contract (19FJ6024P0980) was awarded to Multistack for “FAC-NOB MULTISTACK CHILLER PARTS” (about $14,014, 09/12/24–10/11/24), and another related award (19PK5022P7278) for “LHE-FAC-REPLENISHMENT-MULTISTACK CHILLER PARTS-7904” (about $21,529, 09/12/22–05/25/23) was made to Miscellaneous Foreign Awardees.
